WIL BYERS

enjoy this hobby/profession beyond words, and I do so for many reasons. For example, in this month’s issue I had the opportunity to fly the Blade 500 3D Bind-N-Fly helicopter, build and program the Flame Wheel F550 hexacopter, test some absolutely awesome telemetry systems as well as the new Futaba 14SG transmitter, and help my longtime friend, Gene Cope, test fly his scratch-built 1/3-scale ASK-18 glider. Talk about a fun job or what—it is a great gig! Every year at this time, the flowers start to bloom, the birds sing and the events start to appear on our radar. Oh, and I start to preach about the benefits of attending them. The truth is they benefit you because you get to see models of every kind, see their construction, their radio control systems, and see how other pilots fly their models. It is an all-around great learning experience. Here are just a few that I recommend you attend. Southeast Electric Flight Festival - April 22–28 This is a mega event for electric-powered aircraft. It has been held in Georgia since 2002. Now it is hosted at Hodges’ Field in Americus, Georgia. This is one of the most well run, well organized events you will ever have the opportunity to attend. To say you are going to have a good time at this event is definitely an understatement. It is a blast, and the food is good too. fayetteflyers.com Joe Nall Week - May 11–18 This a truly monumental event. It is now the largest gathering of model airplane enthusiasts in the world. Attendees can fly anything from a 3D airplane to a float plane. The real draw for many modelers is, however, the huge number of scale airplanes that are shown and flown at Joe Nall. Note too, Pat Hartness has been making improvements to the flying site that will make flying at this site better than ever. Don’t miss it! tripletreeaerodrome.com International Slope Race - May 18–19 The ISR group is hosting what has been a legendary slope race in Davenport, California, this spring. It will be held at the site of Big Creek Lumber on the bluffs that overlook the Pacific Ocean. It is a unique glider race in that pilots compete with each other in man-on-man fashion, which makes for some exciting action in the turns and down the straights. I’m planning to attend this annual event because it has no equal. I hope I’ll see you there. davenportisr.com/index2.html Northwest RC Seaplane Champs - July 13 – 14 If you live on the West Coast and you like flying or watching seaplanes fly, you must not miss this annual event at Pine Hollow, Oregon. This event is held at one of the best float fly lakes you will find anywhere, which is at Wamic, Oregon. The organizers have been putting this event on for a number of years now and now want you to know about it. So, dig out your float plane, or put a set of floats on one of your models, and attend this fun competition. You’ll be glad you made the trip. sky-knights.org. F3B World Champs - August 1–11 Glider pilots may want to consider taking a summer vacation in Dresden, Germany. They will have the opportunity to see the world’s best glider pilots go head to head in an F3B competition. For those who don’t know, F3B is comprised of three tasks: speed, distance and duration. The competition is designed to test both the pilot’s skill as well as the overall performance of the glider. Learn more at teamusaf3b.com. Cubs N’ Cousins - August 23–25 If you are a Cub nut like many of us are, you must not miss this huge, fun fly event. It is hosted in Othello, Washington, at one of the best flying sites you will find anywhere. It is super affordable too at only $15 a day. What makes this event super, however, is that it is all about Cubs and airplanes that are considered cousins of the Cub. Talk about a fun event. rc-cubsncousins.com Until next month, keep your batteries charged and propellers balanced.

APC Competition propellers for the intermediate and

advanced sport ﬂyer as well as the competition community. Over 400 pitch/diameters available ranging from slow-ﬂyer electric to High performance Giant Scale Racers.

ASK-18 BUILD PART 1 A DECADE OF PLANNING THAT PAYS OFF IN GREAT GLIDES

My ASK-18 sits next to a fullscale Cessna 150 at the Richland, Washington airport for a size comparison.

A few hundred hours of scratch building are rewarded with this shot of my 1/3-scale ASK-18 in flight over the Horse Heaven Hills.

ASK-18 BUILD PART 1

n the early 2000s I purchased a Rosenthal 1/3-scale ASK-18 fiberglass fuselage, canopy and wing rod as a starting point for a scratch-building project. The parts collected dust in my workshop for several years before I gathered the documentation for the wings, rudder and stabilizer. It was just one of those projects that kept getting put on the back burner. Then too, I had to decide how I would build the flying surfacesâ&#x20AC;&#x201D;foam core or open structure, built up. It took time to gather my thoughts and make the final decision to start the project. Earlier I had assembled a Flair Ka8b. In reviewing its instructions and plans, I decided to build my ASK-18 in a similar fashion. So, a plan of action was put into place in the early stages of the project. Subsequently, the wing, horizontal

stabilizer and rudder were then drafted to size in a solid modeling program and converted to a format acceptable to a CNC machine. A friend then cut the wing parts out

SCRATCH YOUR HEAD ...

Scratch building is not difficult, but it does take time and some planning—let’s call it scratching your head. A few hours in the workshop a day can get a lot of building done. Note: You will want to follow the photos closely as I document this build to understand my processes and procedures.

9 Here is the finished rudder assembly, ready for final sanding and covering. I recommend sanding with 400-grit wet-and-dry sandpaper at this point.

elevator and horizontal stabilizer were cut from 1/16-in. plywood. Sixfoot-long Sitka spruce spar material was purchased from Aircraft Spruce & Specialty Co., while the 3- x 48- x 3/32-in. balsa sheeting was purchased from Balsa USA. At this stage of the build, everything was set aside and again collected dust for a few more years. Your RC Sport Flyer editor, Wil, has been a good friend of mine for 20 plus years. He finally talked me into just building it as a flyer, rather than one of my normal three-year scale projects. He wanted me to share some of my scratch-building techniques with you in the hopes of seeing more unique scale gliders appear at aerotow and slope soaring events. So, I’m going to share my build with you in a five-part series, with maybe a couple of short special build

Rudder I suggest you start with the rudder first. It is the smallest part and the least expensive to redo, should you make a mistake at the get-go. Also, it will prime you for building the horizontal stabilizer, which is very similar in construction. I started by marking the 1/16-in. plywood center for the pivot pins and control horns (photo 1). A 1-1/2-in.-diameter cut-off wheel was used to cut the pivot rod slots in the plywood (photo 2). Holes were then drilled where the control horns would mount to provide a bond between the control horns (photo 3). Thirty-minute epoxy secured the 1/16-in.-diameter music wire pivot pins in the slots in the wood. The leading edge of the rudder consisted of laminating two 3/8-in. balsa together (photo 4), which was profiled to the taper of the rudder post. These edges were then glued to

the rudder’s plywood backbone using Elmer’s® Carpenters’ Wood Glue Max (photo 005). This glue provides an excellent bond between plywood and balsa. A strong, waterproof bond with fast setting properties is ideal for wood construction. This glue, however, provides enough time to work with the parts before it sets. A 1/16- x 1/4-in. balsa strip was glued to the trailing edge on both sides to provide a good bond area for the covering material. Balsa triangles, cut roughly to shape, were glued to form the ribs of the rudder. Using a large, 1/2-sheet sanding block, I carefully sanded these down to the surfaces of the rudder leading and trailing edges (photo 8). The leading edge was then faceted to a nearly round profile before it was sanded round to make the leading edge of the rudder. The

control horns were then positioned on both sides of the rudder and backed with retaining blocks. I used 3/32-in. balsa sheeting to complete the rudder bottom. Also 3/32- x 1/4x 3/8-in. gussets were fitted on each side of the rudder’s ribs, which adds scale detailing (photo 9). The fuselage’s rudder post was made of 1/32-in. plywood and 1/8-in. balsa sheets that were laminated. I had planned to use liteply for the rudder post, but Midwest no longer supplies this material, so my lamination was used (photo 10 & 11). Fourmost Snap Tight large hinges were used for the rudder and elevators. However, the centerline of the lower rudder’s hinge point was too far from the fuselage’s rudder post for a strong support of the hinge. As a result, I used a 7/16-in.diameter wooden dowel—that I cut a 3/8-in. taper into—to extend the hinge point’s position from the rudder post. The dowel was glued through both the rudder post and rear support blocks (photo 12). Once the rudder post was fabricated, it was installed into the fuselage with epoxy along its sides. Once the epoxy had cured, I reinforced the rudder post’s install with 4-oz, S-type fiberglass cloth. The cloth was laid in on its bias. Then a 1-in.-wide paintbrush was used to brush aircraft-grade slow-cure epoxy into the cloth. When you are doing this, you want make certain you create sharp, tight corners where the fiberglass meets the edges of RC-SF.COM

the fin and rudder post (photo 13). Once the epoxy goes green (a term for when the epoxy is set but not fully cured), the fiberglass cloth gets trimmed to the fin’s trailing edge. Trimming after the epoxy has fully cured is much harder. Horizontal Stabilizer Before I started the build of the horizontal stabilizer assembly, the elevator hinge points were located on the 1/16-in. plywood center and cut to the width of the Fourmost hinges—very much like was done for the rudder. Later the plywood spars were drilled for hinges at these locations. Also, the location of the elevator servo must be positioned and cut from the wood before assembly.

The horizontal stabilizer and elevators are constructed in the same manner as the rudder. The exception here was the horizontal spars at the rear. They were cut from 1/4-in. Meranti Marine plywood. It is lightweight and strong, which is what a horizontal spar requires. The leading edge material was cut from 1/2- x 3/8-in. balsa that tapers with the stabilizer ribs from root to tip. Tip blocks were also made of balsa. The center section ribs required notching for the servo mount and were then glued to the bottom side of the plywood center section. Once the adhesive on all the ribs, leading edge and spar was cured, the leading edge and tip blocks were sanded to shape. Then 3/32-in. balsa sheeting was laminated to cover the

bottom of the horizontal stabilizer, which was done in one step. Note that you’ll need lots of little clamps. When the sheeting’s adhesive has cured, the slot locations for the mount bracket were calculated and cut into the wood (photo 14). Then they were transferred to the fuselage. To do so, I positioned the stabilizer on the fuselage and measured it for squareness relative to the fuselage, then double- and triple-checked it. After the location on the fuselage was determined, I cut the bracket slots in their respective locations in the fuselage (photo 15). Next, I had to fabricate two 1/8-in. aluminum horizontal stabilizer mount brackets. They were then inserted from the top of the stabilizer’s 1/16in. plywood center section—the

16 Slots cut in the horizontal stabilizer saddle allow the aluminum mount brackets to drop in and slide back to lock the stabilizer in. The center slot is cut to provide clearance for the elevator halves’ control rod.

Two 1/8-in.-thick aluminum mount brackets protrude from the bottom of the horizontal stabilizer. They mate to the stabilizer retainer mount that gets glued into the fuselage, just under the mount area for the horizontal stabilizer.

18 Horizontal stabilizer retainer mount layout is shown here. As the screw tightens, the bevel on the aluminum bracket wedges into the bevel of mount plates, making for a tight, secure fit.

RC SPORT FLYER — MAY 2013

Prior to installing the mount plates inside the fuselage, the locking system was checked one more time for fit. The clamps are inexpensive but invaluable for this type of work.

ASK-18 BUILD PART 1

19 The horizontal stabilizer is shown here firmly locked in position by way of one 8-32 x 1-in. hexhead cap screw.

The elevator throw was checked several times during construction to make certain that no binding occurred between parts.

top half is built after this step. The brackets will extend through the bottom of the horizontal stabilizer’s sheeting. (photo 14). After each bracket was mounted and alignment rechecked, it was secured in position with 30-minute epoxy (photo 16). Next I fabricated the fuselage’s Meranti Marine plywood horizontal stabilizer mount plates (photo 17). Then the aluminum mount bracket was coated with petroleum jelly as a release agent. The horizontal stabilizer was then positioned on the bracket, and the aluminum mount was pushed tight against the mount bracket (photo 18). The

plywood mount bracket was then secured to the inside walls of the fuselage with aircraft-grade epoxy and clamped in position (photo 19). I checked the horizontal stabilizer for squareness, making adjustments as necessary before letting the epoxy go green. In the epoxy’s green state, the horizontal stabilizer was carefully moved forward so as not to disturb the mount plates, and to make certain the stabilizer did not get inadvertently attached to the fuselage. Any epoxy residue was then removed from the aluminum bracket. Once the epoxy cured on the mount plates, the forward mount

block was epoxied in place. Bass wood measuring 1/2 x 1/2 x 3/4 in. was cut at an angle to accept the 8-32 blind nut set, as flat as possible against the surface. When the epoxy fully cured, the horizontal stabilizer was remounted and checked for squareness. With a 0.140-diameter drill bit, a hole was drilled on center through the horizontal stabilizer, fuselage and forward mounting block—at a slight angle back toward the tail. The reason for not drilling straight down is that when the mount screw is installed at an angle, it causes force to push the aluminum mount bracket back into the angles of the mount plates (photo 20). The horizontal stabilizer mount will then lock in position and will not loosen as it wears. Next I used a drill bit the diameter of the blind nut shank to run through the hole in the fuselage and the forward mount block. Using a long 8-32 cap screw coated in petroleum jelly, I fastened a blind nut inside the fuselage to the bottom of the cap screw. A small amount of 30-minute epoxy was applied to the blind nut flange before the 8-32 cap screw was tightened to pull the blind nut flange flush with the surface of the forward mount block. The 8-32 cap screw was then removed while the epoxy cured. The elevator was then finished in the same manner as the rudder. Hinge locations were marked on the back face of the horizontal stabilizer spar. Then I used a drill bit slightly larger than the threaded section of the hinge to drill holes on center with the spar. The notches in the plywood for hinges make it much easer to drill the hinge holes straight. With the Fourmost hinges snapped onto the finished elevator, less the covering material and the threaded section coated in petroleum jelly, it’s ready to mount to the horizontal elevators. Using 30-minute epoxy and flocked cotton, a wet paste is made. It gets pushed into the hinge holes of the horizontal stabilizer using a kabob skewer. The hinges are then recessed into the holes, taking care to remove any excess epoxy if it appears. The elevators are spaced about 1/64-in. from the spar RC-SF.COM

face, with the upper and lower surfaces flush to each other. The horizontal stabilizer was then supported leading edge down, with its spar level to the working surface until the epoxy cures. The stabilizer was then carefully snapped off its hinges. A 1/4-in. triangular stock was used to fill the gap between the horizontal stabilizer and the elevator. To adjust the fit properly, the elevators were remounted and two business cards used to space the triangular stock from the elevator as it is attached to the spar face of the horizontal stabilizer. Sanding the triangle stock flush with the upper and lower surfaces finishes the assembly. Final sanding and covering was then done (photo 21).

Wil takes off to give the ASK-18 a good running throw but unfortunately trips doing so. Here he is going down on his knees.

It is glider before bodily injury in this shot as Wil throws the glider forward with all his might to get it flying before eating dirt!

WILLIAM BROTHERS PILOTS HOW TO GIVE YOUR PILOTS A LIFELIKE LOOK

e’ve all seen the bug-eyed, scared-out-of-his-mind Williams Brothers (WB) pilot stuck on a balsa plate in a cockpit. With their somewhat comical “thousand yard” stare, WB pilots have accrued their share of derision,

although perhaps undeservedly. With a little effort, a WB pilot can be made to look the part by making a few simple adjustments and additions. I needed a crew for my recent 33-in., 1/15-scale Dauntless refinish, and there are not many small-scale

pilots available. On top of this, what I needed was more than just a bust, since a lot of the crew can be seen in the Dauntless’s greenhouse. Since the WB pilots are a rather truncated representation of the human figure, having only the very

Sanding blocks and grits of various grades, razor saws and a long blade knife are what is needed to work the foam.

I sanded each half of the pilot figure on sandpaper affixed to a piece of glass. Liquid plastic cement is used to join the halves.

I primed the figure and sanded the joint. Then I primed my model’s pilot again.

Here I epoxied the torso to the bust and rounded all the corners as needed to bring it into shape.

RC SPORT FLYER — MAY 2013

WILLIAM BROTHERS PILOTS

The front view shows the space left for the upper arms, which you’ll add in a few more steps.

top of the shoulders and a head, I often modify these figures by adding a partial or full torso, using foam as the medium. For this build I was not going for ultra scale precision; what I needed was something in the cockpit that was reasonably correct and in proportion to the aircraft. A plus here is that Navy pilots wore a yellow “Mae West” life jacket over their flight suits—this would cover any imperfections in the bust. Note that the 1/12-scale WB pilot is really closer to 1/15, so keep this in mind when recruiting pilot figures.

Attach the legs and apply a filler coat. Be careful with the angle of the legs to the torso.

A single block of foam cut to the right length and width was used for the legs. I rarely model the lower legs, as they’re typically not seen.

As with all cockpit details, the most important thing to do is to get the proportions correct. For this, I simply took measurements of myself and divided by 15. Leaving a little room at the shoulders for the arms, I first cut a torso from blue insulation foam and epoxied it to the bust. While foam-safe CA can be used, I like epoxy, as its setting time provides a good grip on the foam. Next, I rounded the torso everywhere except where the legs would go. I then cut a block of foam in the proper proportion and shaped the legs (only to the knees)—hacking out both on the same block of foam. I found that 100-grit sandpaper works the best for rough shaping; anything

more aggressive will result in chunks of foam being removed. Watching the angles, I glued the legs to the torso and then fine-sanded it all to remove corners and ridges and to blend the foam with the bust—humans don’t have corners! I brushed on a filler mix of vinyl Spackle and Polycrylic Satin water-based varnish over all the foam areas and sanded it in when dry. I wound up making some adjustments with the sandpaper after seeing everything in one color and reapplied the filler mix to these areas. The arms are probably the toughest part to get right. For the upper forearm, I used oversized blocks of foam that were correct in length down to the elbow and

The upper arms are modeled with rough-cut blocks of foam the correct length to elbows.

then shaped them after they were affixed to the figure. I brushed on more filler mix and also troweled in filler for any gaps at the shoulder and sanded it all down. It’s easier to make adjustments to the figure before doing the forearms, so at this point I sat back and evaluated my work. The figure should now start to come into focus. If it looks wrong, but you cannot determine why, take some more measurements of yourself and compare these to the figure, particularly the width of the shoulders. Measurements don’t lie! Sand off any offending material slowly, and it will start to look right. When you think you’ve got it, apply more filler mix, sand the figure, apply some

straight Polycrylic and then prime the figure. The Polycrylic will protect the foam from the primer’s solvents. One thing to keep in mind, if you really don’t like what you have so far, is that you can always hack it off and start over—it’s only foam. For a forearm, I cut a rectangular strip of foam, tapered it into a shallow cone and severed a piece the correct length—about an inch on my figure. I then sanded the large end concave to match the contour of the upper arm and affixed the forearm with epoxy and a length of toothpick. And yes, now is the time for more filler mix. The forearm might look a bit short, but don’t forget it still needs a hand.

Even at this scale, I felt a wire armature was the way to go for the hands; thin strands of solder, however, would also work. I described this process more fully in the August 2012 issue of RC Sport Flyer. Once the hands were installed, it was on to painting and a few other details. I made the Mae West life jacket from two layers of facial tissue to which I applied Polycrylic and painted yellow. I simply cut out the correct shape and cyanoacrylate (CA) glued it to the figure. Adding this detail hid all my mistakes! Although I painted the figures reasonably accurately, I cut a few corners by not doing my usual airbrush shadowing and highlighting. The most important

At this point, more filler mix has been applied after the upper arms are shaped.

Earphones are simply a couple of slices of plastic rod of different diameters attached to the head.

Toothpicks should be used to strengthen the forearms, especially if they will not be resting on the legs.

After filling/priming the forearms, I cut off the figure’s head and inserted a balsa support when I reattached it in a more realistic pose.

RC SPORT FLYER — MAY 2013

WILLIAM BROTHERS PILOTS

The effect achieved by repositioning the head is striking, as it implies action instead of a blank stare straight ahead—easy to do!

The hands were made with a wire armature and body filler, and the earphone jacks with solder wire. The finished pilot really looks the part.

adjustment I made to the figures was simply turning their heads, which transformed them into a crew that looks like it’s actually doing something. It’s amazing what this single and easy adjustment makes to a figure. A truncated control stick and earphone jacks add just enough additional detail at this scale, but I could have kept going. I am really hoping that this article reduces the number of “pilots on a plate” out at the airfield and shows you that it’s really not that difficult to transform an average figure into the focal point of your model. The new recruits are shown installed in my 33-in.-wingspan Dauntless. It makes for a nice touch of realism. FOLLOW US ON TWITTER @RCSPORTFLYER

WEATHERING MAKE A TERRIFIC WWI WARBIRD LOOK EVEN BETTER

recently built an E-flite® Albatros D.Va 25e almostready-to-fly (ARF) model. This airplane exhibits exceptional scale fidelity to outline, with very good detailing. The finishing touches, such as the scale cockpit gauges and pilot seat, windshield, flying wires strung between the wings and exposed mock Mercedes engine between two wooden Spandau machine gun replicas, make this model nearly identical to that of the full-scale Albatros. For most modelers, this level of scale detailing is above and beyond their standards, but some prefer that their aircraft appear as if it had just returned from a flight over No Man’s Land. 30

RC SPORT FLYER — MAY 2013

The overall scale appearance of your E-flite® Albatros D.Va 25e will double with these added details. The work is worth the payout.

From tip to tail you will be adding little details and bits of weathering. You can clearly see the dusted weathering along the wing spars from this angle.

WEATHERING

Laid out here are the tools and materials you will need for the job. You can find these at your local hobby and craft stores.

For a credible resource on warbird detailing, you cannot go wrong with a Squadron/Signal or Osprey Publishing book.

While completing a build article on the Albatros for this magazine, I was inspired by a two-part video series on how to weather the aircraft. It was done by John Redman and is found on Horizon Hobby’s product page. I took some pointers from the video and some of my artistic and aviation background knowledge to put together this how-to article. To start my weathering project, I ordered the Osprey Publishing book Jasta 18: The Red Noses. I also purchased a book from Squadron/ Signal Publications’ Albatros Fighters In Action. I wanted them to give me more information on the aircraft and the unit that it was flown in during the War. The Osprey book proved to be extremely helpful in detailing and weathering, while the Squadron/Signal

book provided plenty of photographs and a good-sized sketch of where the panel lines were located on the D.Va’s fuselage. Then the only thing I needed was to gather supplies for the project.

NEEDED TO COMPLETE

• Spray paint Model Master 3-oz Lusterless lacquer • Paint bottles Model Master Rust/chrome/ leather/flat black, 1/2 oz • Material 12 color soft pastel pack • Glue Pacer® Formula 560 canopy • Tools Monoject 412 syringe, precision glue tip, masking tape, pencil

I’ve finished applying fresh strips of canopy glue to the upper wing with my syringe and am beginning to add more to the next spar down. Once dry, they will look like fabric stitches.

You can see the mock wood texture from my painting of the APC propeller as the light shines across it. Long, single-stroke brushes are the trick behind the effective illusion.

Strips of half-round and circle-cut sheet styrene add cover and vent details to the nose of the Albatros. Buttons of canopy glue and some weathering complete the cowl.

WEATHERING

you dropped your aircraft into a mud pit. Rather, you want to create softer stains and marks that are better seen up close—they’ll replicate wear and use over time. After your model’s fuselage has been dirtied, you’ll want to remove its battery hatch and start weathering the Mercedes D.IIIaü engine. To simulate the oil spatter over the rocker arms and the engine shaft, you must wet a paintbrush with the flat black paint and brush it over a paper towel to dry it a bit. Don’t completely clean the brush; just get it to where there is some paint still left on it. In so doing, you can create small streaks and lines. Then use the paintbrush to streak the engine’s rocker arms, where the center shaft meets the rocker cases, and down the arm in easy sweeping motions to get that natural oil stain and drip look.

War is not a clean affair. Neither is aviation, especially in the early 20th century. You won’t see aircraft roll off the factory assembly line, fly to their station, go to battle and come back still looking brand new. Keeping that in mind as you go along will help you when applying your brush to the aircraft. I began weathering my Albatros D.Va the same way John did by spraying over the glossy covering with a lusterless flat lacquer from Model Master. This replicates the matte finish of the fabric covering used on the full-scale aircraft. Next, the bottom of the aircraft needs The completed stitches and subsequent weathering a good wash with a with the pastel powder finish off the top wing for an attractive scale appearance both up close and from colored powder to afar. give it the appearance of operating from the muddy grass strips of early Spring Lomme Aerodrome. You’ll want to grind up about a third of your brown soft pastel into a fine powder and use a brush or your fingers to apply it to the fuselage. Streak it from front to back in long sweeps to give it a proper blend. Again, subtlety is a big part in weathering.

I may have been too generous with the silver, but the light vertical strokes over the engine give it a worn and used look. Notice the black “oil” stains along the rocker arms.

Opting to draw instead of carve for a perfect scale detail, I used a fresh black permanent marker to add the cooling jacket pattern to the barrel of the Spandau machine guns.

The eight symmetrical bolts along the wheels were made with buttons of canopy glue and dusted with brown pastel grounds. Naturally, the wheels were the dirtiest feature!

WEATHERING The engine exhaust pipes experienced a fair amount of wear in service, so apply light vertical streaks of dried chrome paint along the outer edges to help replicate aging. Additionally, you can smear a few spots of the brown pastel powder along the pipes to give them a bit of rust coloring.

WEATHERING Once you’ve finished with that, you can opt to add the engine and cowl covers by using a circle cutter and styrene sheets. These scale covers are positioned in their respective places by adhering to the illustrations in the Squadron/Signal book. These add a three-dimensional detail that can really make your Albatros look fantastic. The .125-in. half-round styrene strips can be cut into 3/4-in. lengths and painted red, which will then simulate the cooling vents. These detail items are mounted to the airframe using either the canopy glue or thin CA.

located on the full-scale Albatros. Allow those to set overnight. Pop off the propeller and use the rust and leather paints to make it look like a wooden propeller. Make long strokes with the paintbrush from the center of the propeller out to the tip. This will make small grooves and lines that will simulate a wooden texture, which gives it that added realism you are looking for in your model. Use the leather as a base and go over it with a dry brush of the rust mixed with a minute drop of black to add darker lines of simulated wood grain. Finally, you are ready to add what is in my opinion the coolest part of the details—the lozenge striping. During the war, the Germans mainly used two different patterns of fivecolor lozenge camouflage patterns on their aircraft. These fabric patterns were stitched in thin sections spanning from the leading to trailing edges of the wing. These sections were taped off and stitched together with strips of colored fabric atop the seams. As pointed out by John in his tutorial video, there were two colors used for this. One was a light blue color, and the other was closer to a salmon pink color. For salmoncolored stripes, you will use 1/16-in. striping tape and paint it with the 34

RC SPORT FLYER — MAY 2013

Model Master Skintone paint. The 1/16-in. tape is recommended for a truly scale appearance, but if you made your stitches on the top of the wings a little too big like I did, you can opt for the 1/8- or 1/4-in. striping tape too. This process of painting and striping takes a long time, so unless you’re a diehard for the lozenge being striped in salmon, you’re best off using the light blue UltraStripe for a quicker detailing procedure.

Once you’re finished, step back and look over your stunning Albatros. It may just leave you awed. While there are many details that will look impressive up close, in the air they will show your Albatros’ beauty overall. Your hard work will pay off on that certain pass where the light reflects off of its wings and fuselage— to the point where you almost believe you are seeing the full-scale WWI airplane flying off to a little sortie.

I used my spare sheet of styrene to add the two covers found on the bottom of the D.Va and added a little more oil weathering than I intended. It still makes for a good scale addition.

kay, who has done their homework and been practicing on the simulator? In the first part of this aerobatics series we went through the importance of using a good simulator and some of the beneficial techniques that help lay a solid foundation for your aerobatic piloting. Learning to precisely control the airplane and put it right where you want it, when you want it, is not something that comes overnight. Now that you have begun working toward that on the simulator, it’s time to get you out to the airfield with a high-end, quality aerobatic airplane that will aid you on your journey of learning to fly all types of aerobatics. Choosing the right airplane for your needs is a very crucial part of this process because it can make a huge difference in your progress. With today’s technology, there are many excellent airframe and equipment manufacturers, but care still must be taken in the quest to find your perfect airplane. Over the past nine years, I have flown a little bit of everything and have experience 36

RC SPORT FLYER — MAY 2013

with all of the major and most of the minor airframe manufacturers. I will help point you in the right direction for this next exciting step!

3D Hobby Shop 87-in. Extra 300SHP

WHAT TO LOOK FOR

In this issue, I will present you with a list of my favorite airplanes in different size categories, but first I want to go over the “Why” factor.

AEROBATICS PART 2 The airplanes in the following list aren’t there because I like the way they look or how they fly for their manufacturer, or because I want to see more of them at the airfield. Rather, I selected them for their excellent flight performance and their ability to perform 3D, IMAC and extreme aerobatics (XA) with precision and class. Extra, Edge, MXS, Cap, Laser, Raven, Yak, Sukhoi … They’re all the same, right? No. I’ve heard from many guys that all aerobatic airplanes look the same, but that’s like saying that all Formula 1 cars look the same. First, there are many qualities that they all must retain to perform well in all types of aerobatics. While there are some biplanes that perform very well in these three types of aerobatics such as the Hangar 9® 100-cc Beast, I will focus on monoplanes because they really have the edge, especially in precision aerobatics. Extras, Edges, Yaks and Sukhois are the most common airframes in competition aerobatics for many reasons and will be my focus for now. Apart from the differences in the cowlings, the overall layout of the airplanes looks similar, but here are the predominant aerodynamic differences: The Extra, Yak and Sukhoi all feature a symmetrical airfoil on the Extreme Flight® 60-in. Extra 300 EXP

DW Foamies 40-in. Extra 300 wing, and the wing has a tapered leading edge. The Edge 540’s wing has a fully symmetrical airfoil as well, but it has a perfectly straight leading edge. The tapered leading edge of the Extra, Yak and Sukhoi lends itself more to precision and extreme aerobatics because the taper allows the pilot to stall one wing before the other. A well-designed airplane will stall straight forward without dropping a wing, but the tapered leading edge allows the pilot to choose which wing he wants to stall

such as in a snap roll or precision spin. Because of this, these airplanes are better choices for precision aerobatics. The straight leading edge of the Edge 540’s wing lends itself to 3D aerobatics and is extremely stable in all attitudes. The fact that both wings always want to stall together is somewhat of a hinderance in precision aerobatics but can be helpful in some 3D maneuvers. The tail moment is another factor that should be considered when selecting the airframe. This is the distance from the wing’s center of pressure to that of the horizontal stabilizer’s. The longer this is, the easier it will be to draw perfectly straight lines, while a shorter tail moment will produce more control authority in pitch and yaw. In general, the Extra 300 has the longest tail moment, but almost all modern remote control aerobatic airframes are stretched slightly to yield smoother and more precise flight characteristics, while the control surfaces have been enlarged to produce the insane control authority that is required in 3D and XA aerobatics. The best aerobatic airplanes are almost as long as their wingspan. All of these airplanes have a different wing placement, each lending itself to different maneuvers better than others. The Edge’s wing RC-SF.COM

Extreme Flight® 104-in. Extra 300 is shoulder mounted right below the canopy and is very high on the fuselage. This position makes upright harrier flight very stable and easy but is not quite as good in precision aerobatics. The Extra 300 mid-wing is my all-time favorite airplane and feels extremely neutral in all types of aerobatics due to its wing being in the center of the fuselage. This position is the best of both worlds and is excellent in all types of aerobatics. Most models of the Yak-54 share this approximate wing position. The Sukhoi has a low wing, which is not bad in any type of aerobatics but is not ideal either. Most models of the Sukhoi have a slightly raised wing that helps aerodynamically. Different models of the Extra also have a lower wing position. There are other small differences between these types of airplanes, Extreme Flight® 110”Yak-54

RC SPORT FLYER — MAY 2013

but the ones addressed above are the most significant. Each airframe manufacturer has its own techniques for tweaking these designs to perform better as RC models, and I have a couple of things to mention about these. • Wing Loading: There is a huge misconception I want to put straight. An airplane with a lighter wing loading does not immediately fly better. There are some companies that focus on building extremely light 3D airplanes with oversized wings to reduce wing loading. These airplanes hover and harrier very easily, but their weight severely limits the pilot in precision and XA aerobatics. The floaty feeling comes at a cost, and I would advise you to steer clear of these airframes, as they will teach you some bad habits.

An overly high wing loading is also undesirable, but you want to have enough weight behind the airplane to yield the inertia required to carry it through different maneuvers. For the best results, you need to start with a well-designed all-around aerobatic airplane. • Side Area: Most of the good aerobatic airframes today have fuselages with lots of side area. This helps in many aspects and makes the rudder more effective. Some designs have the canopy slightly forward of the scale location, which also helps put more side lift forward of the center of gravity. Side Force Generators (SFGs) are becoming very common and help in the same way.

SIZE

Now that you have a basic understanding of what we’re looking at in airframe designs, it’s time to decide how big you want to go. For beginner aerobatic pilots, I strongly encourage buying a profile 3D foamy. A good foamy, coupled with a good simulator, is the best way to learn this type of flying. Well-designed foamies are more forgiving and easier to fly than a built-up aerobat, but they still allow you to practice all the new extreme maneuvers. Regardless of the size of aerobatic airplane you fly, I highly recommend getting a good foamy as a Guinea pig, as they are much easier to repair than a high-end aerobatic airplane.

AEROBATICS PART 2

Extreme Flight® 60-in. Edge 540T EXP

BIGGER IS BETTER

Well, at least to an extent. When learning aerobatics, it is easier on the mind to fly an inexpensive airplane, but the larger the airplane is (within reason), the easier it is to fly. For instance, a 40%-scale airplane is almost as easy to 3D as a foamy, and it’s even easier to practice precision flight. I do not recommend starting with an airplane this size, but the larger airplanes are used in competition for a reason, and it’s not because they’re harder to fly! My favorite size to fly for fun is a 60-in. electric-powered airplane. It’s just big enough to feel light and precise but isn’t too hard on the pocketbook. After mastering a 60in. airplane, jump to a 50- to 60-cc airplane. This jump is very substantial, but you will be amazed by how easy a high-end, giant-scale aerobatic airplane is to fly! Everything seems to happen in slow motion as compared with the smaller airplanes—wind is fought off like nothing, and the wing loading is light, due to the large size. FOLLOW US ON TWITTER @RCSPORTFLYER

Some pilots who aren’t concerned with the price tag jump straight into a 50- to 60-cc airplane after mastering their foamy, and if you are confident

enough, I would not discourage you. It is however, a notable investment. Here is a list of my two or three favorite airplanes in each size:

While it is the best-designed Edge on the market, precision aerobatics are not quite up to par with the Extreme Flight Extra 300 but are still very good. This airplane loves to tumble and will wad up so tight that your head will spin with it! • 3D Hobbyshop 87-in. Extra 300SHP This airplane is one of the smaller 50- to 60-cc-class airframes, but it still has a great flight envelope. It is optimized for 3D and loves low and slow flying.

Hangar 9® 35% Extra 300

• Hangar 9® 35% Extra 300 Mike McConville did an excellent job designing Hangar 9’s 35% Extra 300. I consider it the second-best all-around airplane. It is very precise, aggressive, stable and true, and it is a very good competition platform for IMAC and freestyle. • Extreme Flight® 110” Yak-54 Extreme Flight’s Yak-54 is a true masterpiece that captures the look and feel of the huge Russian-built aerobat. This airframe was tweaked extensively to produce excellent precision aerobatic capabilities while maintaining the awesome 3D characteristics of a Yak. Its wing loading is very light, rolls are perfectly axial and control authority is very smooth in all flight conditions, making it a great competition airplane.

Hangar 9® 3.1M Sukhoi 26MM

• Extreme Flight® 125-in. Extra 300 As the bigger brother of Extreme Flight’s 104-in. Extra 300, this is in my opinion the most capable and precise IMAC airframe in the ARF world! Extreme Flight worked very meticulously for many years to perfect this airplane, and it will stay with you through the top levels of precision and freestyle aerobatic competition. Its long tail moment allows you to draw laser-straight lines effortlessly, making this the ideal IMAC machine! • Hangar 9® 3.1-M Sukhoi 26MM Hangar 9’s big Sukhoi is another of Mike McConville’s excellent designs and is another great all-around airplane, capable of low and slow 3D, IMAC and everything in between. The big round cowl helps keep a fairly slow and constant airspeed and looks great too. • Performance Aircraft Unlimited 123-in. Extra 300SP If you like scale airplanes that fly well, you will like the PAU Extra 300SP. This airframe is extremely close to perfect scale and performs beautifully.

OVERALL

This list represents what are—in my honest opinion—the best ARF aerobatic airplanes on the market in these size categories. As you probably noticed, the list is comprised of almost 50% Extreme Flight® airplanes. I have flown these airframes from my first competition until now, and I think they are the most welldesigned, all-around 3D, IMAC and XA aerobatic airplanes available. Their flight performance is unmatched, and their quality is second to none. They have many more airframes that my list was too short to include, but you will be “golden” flying any of their airplanes. They will stay with you all the way to the top of the most demanding aerobatic competition flying. My competition model and absolute favorite airplane of all times is my Extreme Flight® 104-in. Extra 300, which I am again preparing to compete with in the 2013 Extreme Flight Championships. Hangar 9® has also recently come out with some amazing airplanes. I have a lot of experience with them, and they have my full endorsement as machines that will do well in this arena. I believe that the best progression of airframe sizes for someone wanting to get into aerobatics is to start with a foamy. Once the foamy Performance Aircraft Unlimited 123-in. Extra 300SP

Twisted Hobbys 32-in. Crack Yak is mastered, move up to a 60-in.-size electric-powered Extra 300 or Edge 540 and then jump up to a 50- to 60-cc-size, giant-scale aerobatic airplane. You will truly be amazed by the performance of these airplanes as soon as you fly a giant-scale aerobat. Although landing takes some skill in a tight space, these are the easiest non-trainer airplanes to fly. When you put them on a line, they stay on that line until you command otherwise. They fly what you command them to fly—no more, no less. It is truly a one-of-a-kind experience that makes you realize that you, the pilot, are the

only limiting factor to the maneuvers that are possible! Well there you have it. Make the decision about what size aerobat is right for you and go ahead and purchase it. In the next issue of RC Sport Flyer magazine, I will help you set up the airplane in such a way that it will aid you along the journey of learning aerobatic flight, and at the same time be a competition-worthy machine. Until next time, practice, practice, practice! Photo credits Jerry Smith, Wil Byers, Tom Seres, Jim Smith, Higher Plane Productions

14SG

ENJOY TELEMETRY AND STATE-OF-THE-ART TECHNOLOGY AFFORDABLY

henever the latest and greatest technology is released, you can expect to pay a pretty penny to get in on the action. In the RC industry, telemetry modules and supporting receivers are the new hot items for the RC pilot. High-end transmitters like the Futaba® 18MZ support telemetry and many features that keep the price above the average RC consumer’s

budget. The new Futaba 14SG transmitter, however, incorporates the professional-level pilot features into an ergonomic transmitter case, and does so at a very affordable price.

PACKAGE CONTENTS

The Futaba 14SG 14-channel digital 2.4-GHz transmitter ships in a durable box that encases the radio

in protective styrofoam—two thick foam packaging halves. The package includes a well-written manual that explains everything you’ll need to know about this new radio system. The 14SG comes with a 6-V 1800mAh nickel-metal hydride (NiMH) battery pack, a 12-V AC charger, a R7008SB receiver, a switch harness, a LiFe spacer, a neck strap and an adjustment tool.

THE TRANSMITTER

The 14SG is designed to fit perfectly in any pilot’s hands. Weighing in at just 32 oz, it is lightweight yet very well balanced. The switches are extremely well placed, so you will not be searching for them as you fly your model. This transmitter supports FASSTest, FASST and S-FHSS 2.4-GHz systems for versatility with newer and older model receivers. The sticks are comfortably positioned and travel to their limits without requiring you to overextend your fingers. Their lengths are also adjustable. Your hands fit well against the soft rubber grips on both sides of the transmitter too. The front face of the transmitter is clean and organized. The neck strap’s connection is located right at the center of gravity (CG) for the transmitter and just below the power slider on/off switch. A 3- x 1.75-in., 128 x 64 resolution backlit LCD screen resides at the bottom of the face. A touch-sensitive pad to the right of the screen is used for programming, while a pair of silver buttons sits on either side of the transmitter. The left button is the Home/Exit button, while the right is the User Menu/Servo Monitor (U.Menu/Mon.) menu button. A pair The attractive Futaba 14SG features plenty of toggles in a clean and organized layout that gives you comfort and versatility.

FUTABA® 14SG of digital trim switches borders each stick as well. At the top are two volume dials for the two alarms. Built into the top of the 14SG are four switches, two on either side— two long throw and two short throw. On the front right corner are a pair of three-position switches, while on the top are a three-position switch and a momentary two-position switch. On the front left corner are the same two switches mirrored from the right, while on top are a three-position and two-position switch. Each switch is easily reached and toggled. Behind the top is the metal handle. It is sturdily mounted to the transmitter and far enough for an easy grip. On the backsides of both corners are sliders (potentiometers). Both are easily actuated and well placed. A headphone port is near the bottom of the transmitter, and the trainer port is in the center. On the left side of the transmitter near the bottom is the charging port for the NiMH battery. The battery compartment is on the bottom of the transmitter. The slot for the SD card can also be found there. SD cards can be used for external model memory and software updates to the transmitter. The touchpad and program dial are really easy to use too. Just be careful to make sure that when you’re using it, you aren’t resting your finger against the body of the transmitter. The contact could make it difficult for the pad to read your inputs. It is, however, super easy to use when navigating the menus and programming values into the transmitter’s memory. However, that is just scratching the surface of this transmitter’s capabilities. If you really want to be impressed, you will want to know what it can do inside. What makes the 14SG a winner is the repackaging of the technologies debuted in the 18MZ, with many now built into a transmitter that is much friendlier to your wallet. Specifically, telemetry comes as a huge feature of this system.

advantage of Futaba’s telemetry modules. In the FASSTest 14-channel mode, any of the rpm sensors, atmospheric pressure sensor and GPS sensor can be read by the transmitter. The screen that is home to the data can be pulled up on the transmitter in one of two ways: Either you can press the Home/ Exit button or you can navigate to the Telemetry submenu under the Linkage menu. Installed sensors are automatically registered once the transmitter and receivers link, with the exception of duplicates. For example, you can use multiples of the same sensor hooked up to your model, such as two optical rpm sensors for a twin-engined model. However, you will first need to program which sensor is which using the S.Bus connector on the back of the transmitter. You simply connect the sensor and S.Bus hub to the

Looking down at the top right of the 14SG you can see the layout of the switches and their written identifications. Just behind the SH switch is the knob to the rear slider.

transmitter and pull up the Sensor submenu from under the Linkage menu to program the sensors individually. Once in the telemetry screen, you’ll notice the clear organization of the data right off the bat. You can easily scroll through the different panes of data for each module on any of the three pages. Selecting one will allow you to program the alarm parameters. The alarm is a fantastic addition to the system because it can be programmed with minimum and maximum values that trigger it. For example, an alarm set with a maximum of 1000 ft will sound if the aircraft soars above that height. You can also select four different types of vibrations (Vibes) that can be triggered with the alarm.

PROGRAMMING

The 14SG menus and programming features are all very easy to use. The touchpad allows you to select and explore the numerous menus. Each menu is laid out in a clear and readable format that any pilot can understand. The middle of the 14SG is home to the antenna and two rotary dials on top, power switch in the center and neck strap hook mount and LCD screen at the bottom.

settings that apply to all models. Its submenus show servo position, dual rates, mixing, pitch and throttle curves, throttle delay, snap roll, fuel mixture, gyro and motor settings. These options allow for tremendous control over your model and make the 14SG an attractive transmitter for beginner all the way to advanced pilots. The U.Menu/Mon. button allows you to access the servo monitor screen with one click or the user menu when held continuously. The user menu is another customizable shortcut option designed to allow the pilot less time in the programming menus and more time in the air. The user menu lets the pilot program ten Strips of rubber flank both sides of the 14SG for a comfortable grip. At the bottom of the left side is the battery pack charging port.

The Home screen provides all the necessary visuals for everyday flying. The transmitter’s battery voltage, digital trim positions, timers and model name and type are all displayed by default. You can start and stop the timers by scrolling to them with the touchpad and selecting them. If you hold the Return button while the timer is selected, it will reset. To access the System, Linkage and Model menus you only need to double-tap “Sys” for System, “Lnk” for Linkage and “Mdl” for Model on the touchpad. Once in the menu, you can scroll through the different submenus with the pad or browse between the different pages with the S1 button.

CONCLUSION

The Futaba 14SG has plenty of options and comfortable handling that make it a desirable transmitter for pilots looking to get more out of their aircraft and flying experience. The simple menu interface and ergonomic case design, combined The bottom of the transmitter is home to the battery bay where the battery is stored. It plugs into the power port next to the SD memory card slot. For our range test, we wired the Futaba R7008SB FASSTest 2.4-GHz receiver to a servo and a 6-V 3000-mAh NiMH battery, and mounted them to a piece of wood.

FUTABA R7008SB 2.4-GHZ RECEIVER Originally released with the 18MZ and now available for the 14SG, this eightchannel, 2.4-GHz receiver incorporates the latest FASSTest system for reliable and bidirectional communication. At 0.38 oz, 1.9-in. long and 0.98-in. wide, the R7008SB is an excellent fit for most models. It includes a 0- to 7-V extra voltage port next to its dual antennas. The two antennas allow for improved all-around reception when arranged at a 90-degree angle from one another. These features make this receiver an excellent choice to pair with the new 14SG. However, what makes this receiver truly impressive is the FASSTest and S.Bus2 systems. FASSTest FASSTest is the latest in 2.4-GHz spread spectrum technology from Futaba. It turns the incredible FASST (Futaba Advanced Spread Spectrum Technology) signal into a bidirectional system that allows both the transmitter and receiver to send and receive data from one another. This opens up the ability to stream telemetric data from onboard the aircraft to the pilot below. FASSTest uses the suite of new technologies and methods of the FASST system that greatly improves communication between transmitter and receiver. It shifts through hundreds of channels per second to ensure that there are no channel 50

interruptions. And importantly, it allows multiple airplanes that use remotecontrol equipment and that operate on the same frequency band to be flown at the same time. The receiver is also loaded with Pre-Vision™, which applies errorcorrecting techniques to incoming data to ensure it arrives correctly. The system also incorporates Easy Link™ transmitters for near immediate binding once the transmitter is powered. S.Bus2 The S.Bus system is designed to run multiple servos off a series of hubs that connect to the S.Bus receiver port. S.Bus2 also uses that system to send the telemetry data to the transmitter from systems that are installed in the aircraft. The coolest part of the system is apparent when you are setting up your aircraft. Install the servos to the system in the airplane however you like and program them to their function. Once they’re programmed, you can plug them in anywhere, and S.Bus2 remembers their function. The S.Bus2 system is an incredible advance in technology, as well a terrific new feature that is supported by the 14SG’s system.

FUTABA® 14SG The 14SG went 5.1 mi before communication was lost. Compared with other radios tested for our December 2012 issue, the 14SG rates exceptionally well.

AURORA 9 TELEMETRY GET REALTIME INFLIGHT DATA WITH AN AURORA 9 AND A HITEC® TELEMETRY SYSTEM

The HiTec Aurora 9 is one of the best transmitters available on the market today and features a terrific telemetry system.

e’ve talked about the Hitec RCD Aurora 9 transmitter and some of the many sophisticated features it has built into its memory and circuitry. The Aurora 9 incorporates modern-day, very, very large-scale integration (VVLSI) circuit technologies and computer-aided design to optimize pilot control over the aircraft as well as to enhance the comfort of transmitter operation. It is a system that employs Adaptive Frequency Hobby Spread Spectrum (AFHSS), for superior range and control. If you look even deeper into the Aurora 9’s capabilities, you’ll

The HiTec telemetry sensors are joined to a sensor station which is then connected to the receiver through one of the open channels and the data port.

discover that it provides an incredible telemetry system that is both one-of-a-kind and very impressive.

THE AURORA 9 TELEMETRY

The Hitec Telemetry

RC SPORT FLYER — MAY 2013

System is made up a series of sensors that are connected to an on-board sensor station (HTS-SS), which interfaces with the radio’s receiver. The sensors have dedicated ports on the sensor station, which means you can either use some or all—you make the decisions as to what data you want to get from your airplane. The sensors include those that can monitor fuel level, temperatures from -40 to 200 degrees Celsius, revolutions per minute (optics or magnets), and a global positioning system (GPS) that measures altitude, speed and position (longitude/ latitude).

HITEC® AURORA 9 TELEMETRY The data is displayed on the transmitter’s easy-to-read, 5.1-inchwide, backlit touch screen. This means it is easy to see the telemetry data and easy to navigate the menus. Simply touch the wrench icon to access the System Menu, select Sensors, and select the data sensors your airplane has been fitted to carry. If you’re looking for all the data at once, you can touch “Cockpit” under the Sensors menu and have nearly all of the information displayed in real time and on one screen. In the Battery menu a low-voltage warning can be set to alert you as to when the battery in an electricpowered airplane is running low. As the manual recommends, LiPo batteries should not be allowed to drain below three volts per cell, and the warning should be set accordingly—just above three volts for a single-cell battery, above six volts for a two-cell pack, and so on. Having that data available, and warning(s) set can save the model’s battery pack, or even your airplane, should the pack’s voltage fall too low for proper control. You’ll be interested to know that the Temperature menu let’s you monitor up to four sensors at once. The names for each sensor can be renamed to respective functions, such

as “ESC” for the speed controller and “MOTOR” for..., well, you get the picture. In the center of the menu is a display that reads the maximum, average and minimum for a particular sensor you select. Don’t fret if the unused sensor items are all reading -40; that’s the default value for any unplugged temperature sensor. The RPM menu allows for two rpm sensors to be named and monitored. When using an optic sensor, the menu allows the pilot to choose how many blades are on the propeller. You’ll want to select “Prop-M” for the magnetic sensor. The GPS menu features all of the specific data for the latitude and longitude position, speed, altitude, date and time, which are displayed in real time. Adjustments to the time, date, unit of measure (metric or imperial), and whether the altitude is gauged as absolute (above ground level) or relative (above sea level) can be made by touching the Setting icon in the lower-right corner. All of this data can be found in the Cockpit menu as well. In fact, the Cockpit menu is where the fuel level data is displayed. Cockpit has everything! The Cockpit menu is just one option. There is a second screen option—and my favorite feature

about the Hitec Telemetry System— that allows for all of the telemetry data to be displayed in real time, with the option to record it and then replay it later. Using the HPP-22 PC interface device, your computer monitor can become a digital cockpit for your aircraft, with a neatly arranged window full of gauges. They display all of the live data you get from your airplane’s sensors. The device connects to any standard USB port and uses an S-connector cable to bridge the HPP-22’s P1 port to the Spectra 2.4-GHz module on the Aurora 9 transmitter. Once the interface device is connected to the computer and transmitter, you will turn on the Aurora 9 and power up the aircraft. Then the magic happens. You can even re-arrange the gauges on the screen to the configuration you want for the data displays. I’ve not seen another transmitter and telemetry system do that. If that isn’t enough to excite you about this telemetry system, Hitec has arranged for the Aurora 9, Spectra 2.4-GHz module, Optima receivers, and the telemetry systems to accept updates as they become available. Thus newer versions of the firmware can be installed to update your model’s telemetry systems, which is nice because the systems

Under the System menu you will find the Sensor menu where you can view your model’s installed sensors and their telemetry data.

The Sensor menu will automatically be populated with the connected and active sensors. The firmware must be version 1.07 or better to see this.

The GPS sensor screen shows the model’s latitude, longitude, altitude and airspeed. GPS racing is now an option.

The rpm sensors screen shows the rotations per minute and can be adjusted for the number of blades on the propeller.

The four temperature sensor readouts are viewable on the Temp screen. The minimum, maximum and average temperatures for the flight are also shown.

The Battery screen shows the receiver battery voltage and its minimums and maximums. A warning can be programmed from this screen as well.

The Cockpit screen shows the two rpm, airspeed, altitude, fourtemperature, battery voltage, current and wattage readouts at one time.

are changing all the time. Now that’s looking ahead and keeping the customers’ needs in mind. Getting these updates is just as easy as connecting the hardware to the HPP-22 and a computer, and then downloading the latest revision.

CONCLUSION

You already know the Aurora 9 provides you with lots of RC power and performance, doing so at an affordable price. Couple that with the Hitec RCD’s telemetry systems and you’ll reveal a performance package that is sensational. As far as telemetry goes, the incredible amount of information that can be gathered by the Aurora 9 (software

DX18 TELEMETRY REAL INFLIGHT FEEDBACK FROM YOUR AIRCRAFT VIA 2.4 GHZ

e have covered the advanced features that make the Spektrum® DX18 transmitter the top of its brand in terms of performance and ergonomics. Complimenting the DX18’s ease of use and design is its support of the Spektrum new telemetry suite. With a Spektrum telemetry module and the DX18 transmitter, you can now unlock your aircraft’s potential by way of real inair flight data, which will let you enjoy your piloting experience and make your aircraft safer to fly.

TELEMETRY

Spektrum’s telemetry system is comprised of a telemetry module that interfaces with their range of sensors. There are two models of the telemetry module that work with the DX18 transmitter. The first is the TM1100 DSMX Fly-By module. It is compact and designed for use in park flyers and small models. Because of this, the TM1100 does not support the X-Bus telemetry sensors. The second is the TM1000 Full-Range module that can be placed in larger aircraft, where internal space is available to use Spektrum’s full sensor suite. Spektrum currently offers voltage sensors for EC3, Deans, JST, servo and flight packs. They also have sensors for temperature, airspeed, 40-G and 8-G-force, altimeter, rpm and brushless rpm, JetCat turbine and current sensors. Note that you will use a data lead to connect the telemetry module to the Spektrum receiver’s data port. The module can then send the necessary sensor signals to the DX18 56

by way of the 2.4-GHz bidirectional signal. Accessing the DX18’s telemetry menu is extremely easy. You just open the transmitter’s Function menu and navigate to the Telemetry menu, which is near the bottom of the Function list. The Telemetry menu allows you to see which sensors you have enabled and displayed on your menu screen. There are 12 entries

you can program—you’ll have the option for them to remain empty or stream telemetry data from an installed sensor. To edit an entry, select it and use the roller to scroll through the different sensor options until you reach the sensor type you want. Then select it by clicking a second time. This will bring up the sensor’s value options to program, if the data screen for that sensor is active or inhibited. You’ll also be able to set the minimum and maximum values and whether the alarm for them is active or inhibited. Once the sensors are programmed and assigned in the

SPEKTRUMÂŽ DX18 TELEMETRY Telemetry menu, you will return to the main menu screen. There you will use the rolling selector to navigate between the different sensor screens. Accessing these screens will let you customize them from the Telemetry menu under Settings. There you can select whether you wish for the data to be displayed automatically, or by way of the roller in place of the main menu screen or have them inhibited. You can also change the units of measurement between US standard or metric values. The first telemetry screen that gets displayed on the DX18 will be for detailed information for engine/ motor rpm, voltage and temperature sensors. On the left of the screen are the data readouts for these three sensors. On the right is the voltage for the receiver pack. If a sensor is not installed or enabled, a series of dashes will appear in place of the data. You will also see that the digital trim tabs do not disappear when

The TM1100 Fly-By Telemetry Module is seen here installed to the AR7010 receiver. The TM1100 is more compact to allow telemetry sensors to be installed in smaller models.

The main screen of the DX18 can either be scrolled from or disabled to show the multiple sensor screens when using the telemetry feature.

The main telemetry screen displays the voltage, rpm, and temperature data from the installed sensors as well as the receiver pack voltage.

You can see the RPM values changing as we test the telemetry signal. Notice that when data is not provided, the values will either be left at zero or dashed out.

A secondary telemetry screen shows just the data from the voltage, rpm and temperature sensors in larger font for easier reading while flying.

The altimeter and airspeed sensor data are shown on the same pane. Notice that regardless of which screen you are in, the digital trim tabs are still visible.

The minimum and maximum values for each sensor are displayed on their own screen for easy reference without having to dig though the menus.

The G-Force sensor measures and displays the model’s current X, Y and Z forces to the left, with the maximum and minimum values to the left.

switching from the main menu to the telemetry screens. Importantly, they are viewable at all times. Following the detail screen is another screen that displays the same three sets of data, but larger and stacked in the center of the screen for easier viewing. This allows the data to be seen clearly with just a quick glance at the screen, which means the pilot does not have to hunt for the data on the screen. The altimeter sensor screen displays the altitude of the aircraft followed by its airspeed. These values are displayed in large letters and are also easy to read. The DX18 also provides a minimum and maximum screen. It displays the current settings for minimum and maximum values for each sensor. This provides an excellent quick reference for pilots. The G-Force sensor screen displays the different positive and negative forces of gravity against all three axes. Their maximum and 58

minimum limits are also displayed to the right of the data. The GPS sensor screen displays the aircraft’s speed and altitude at its top, with the respective minimum and maximum values to the screen’s right. Below is the current heading, latitude and longitude, and time active. You can record the telemetry data as well. It is saved to the installed SD memory card by enabling data logging under the Telemetry menu, which is done through File Settings. There you can enable/disable data logging and select an 8-character file name. You can download this data to your computer for analysis, which is great for post-flight evaluations.

STI™ ITELEMETRY INTERFACE

Spektrum’s telemetry system supports a mobile app for your iPhone/iTouch/iPad device that can receive and display your aircraft’s telemetry data. You’ll need to buy the STi™ module. It can then be plugged

into the bottom of your device. You’ll want to get the free downloadable STi app. The app will work with whichever models you have telemetry gear installed in. The module must be bound to the respective telemetry hardware system. To bind the STi module to your aircraft’s radio system, you will need to connect the telemetry module and sensors to your model’s receiver. Then you will put the receiver in bind mode. Next you must connect your STi module to your iPhone or other mobile device, and open the STi app. You will create a new model and set it to bind. The lights on the receiver, telemetry module and STi module will begin to blink. You must then put the DX18 into its bind mode. Once bound, your STi app will be ready to receive data. The app has a series of six screens that display live and stored telemetry data as colorful gauges and forms. The first screen shows the airspeed, altitude, rpm, temperature and flight

The fourth screen shows all of the maximum stats for all sensors. The fifth screen is the Flight Log screen that shows all stored data. A sixth screen allows you to choose either to graph or replay the log files. The settings for your selected model in the STi app can be modified by pressing the cog in the lowerright corner. There you can edit the model name, gauges setup, model photo, frames and hold values, rpm, flight pack battery, receiver and temperature parameters, alarm preferences, log preferences, enable/disable voice annunciation telemetry settings (or which items to announce) and the playback interval.

CONCLUSION

Spektrum’s telemetry system is outstanding. It is made even better when in use with the Spektrum DX18 transmitter. The menus are super easy to navigate and programming is quite intuitive. The STi app makes reading the data fun because it has cockpit-like gauges, not to mention it is super convenient to use at the airfield or even when you are atop a mountain slope soaring. I absolutely recommend setting up your aircraft with the Spektrum telemetry system, as well as using the very powerful DX18 transmitter. It doesn’t get better than knowing what your model is really doing in flight. The STi module and app from Spektrum make for a very unique and cool way to monitor and experience your telemetry data from your mobile device.

DC-16 TELEMETRY GET AIRCRAFT PERFORMANCE AND POSITIONING WITH THIS SYSTEM

he state-of-the-art JETI model DC-16 is a powerful, intelligent and user-friendly transmitter. As you may recall the basic system was reviewed in our December transmitter issue. Its high technology approach to features and design gives RC pilots more control over their airplanes, helicopters and gliders than ever. One of the things that makes this radio stand out from the others is its telemetry systems and the way it displays this information to the pilot/copilot. Moreover, Jeti is adding new programming features and sensors almost monthly, which means you get added value when you buy this new high-end RC system.

DC-16 TELEMETRY

JETI’s telemetry system is comprised of a number of easy-toinstall sensors and data processing modules. JETI reworked a number of their original products to make them deliver state-of-the-art functions in their unique 2.4-GHz radios and receivers technology. This new series of Duplex products are labeled with “EX,” and they greatly improve on JETI’s original Duplex 60

models. The new line of EX receivers supports telemetry with bidirectional communications between them and the JETI transmitter. To use these new sensors with a JETI radio is easy. To connect a sensor to an EX receiver you simply connect the triple core cable into the Ext. port on the receiver. If you have multiple sensors, you can connect a Jeti Expander E4 EX module to the receiver. It will let you expand the number of available sensor ports in

intuitive display and recording of the data from both Duplex and Duplex EX systems. The main display desktop, the largest part of the screen, is made to show all of the telemetry data you’ve defined that you’ll need to see, and the different alarms you’ve set. In the status bar above it there is a solid, square icon that, when visible, indicates when the telemetry data is being recorded. The DC-16 can also record the telemetry data to its internal SD memory card, which can then be replayed later on a PC. You can use a USB cable between the DC-16 and your computer too. When used, you can then view telemetry data on the computer’s screen (a laptop) for the airplane you’re flying, or store the data for analysis later. The data is stored on the DC-16 under the Log directory file as .log files. When downloaded to the computer, the log files are viewed using JETI’s FlightMonitor software. Each log has a date stamp that reads year/month/day. Telemetry recording can be set up under the Other Model Options submenu that resides under the Advanced Properties programming menu, accessible from the Main Menu. You can set up a switch, knob, or stick to enable and disable telemetry recording too. You do so by selecting the Start-logging switch option. Unlike most other telemetry-supporting transmitters, because it is designed into the DC-16, there isn’t a real main telemetry setting menu.

MINI VAPOR BNF A PERFECT INDOOR FLYER FOR JUST ABOUT ANYWHERE

one. I’d flown the Vapor, but the new micro Mini Vapor looked like a model that would be super fun to fly.

THE BOX

he original Parkzone® Vapor is a well-known and well-flown slow flyer that is perfect for the indoors. At just about any indoor fly-in, you’re bound to find one of these ultramicro, ultra-lightweight aircraft flying about and giving its pilot hours of enjoyment. Following the Night Vapor—a Vapor with LED lighting attached—is the new Mini Vapor. When I saw this little model on the shelf of the hobby shop in my town, I just had to have

The box the Mini Vapor comes in not only protects it well during shipping but also doubles as an excellent carrying case.

Inside, the Mini Vapor and its LiPo battery and charger are safely packaged and protected by the strong styrofoam insert.

RC SPORT FLYER — MAY 2013

The Parkzone Mini Vapor® comes in a small, attractive box that doubles as a carrying case. Inside, your Mini Vapor fits snugly between the styrofoam insert and two styrofoam braces that are locked down with tape. Along with the airplane comes a single-cell 3.7-volt 30-mAh LiPo battery, charger and four AA batteries to power the charger. The Vapor is trimmed in a translucent red-and-yellow design with some areas of transparent covering. The covering is a lightweight PET film overtop the composite plastic and carbon fiber wing structure. The fuselage is a small carbon fiber tube with a 3-in-1 receiver/servo/electronic speed controller (ESC) board sitting atop its center. The Mini Vapor is powered by an 1S coreless brushed motor that turns a 125 x 39-mm propeller. All together, this aircraft makes for a very lightweight and slow indoor flyer.

The ParkZone Mini Vapor BNF comes with an assembled Mini Vapor, a single-cell LiPo battery pack and a one-cell LiPo charger with four AA batteries.

IN FLIGHT

Let me start by saying I had a lot of fun flying this little model. I was able to take it off from our office floor in just over a foot, and it lifted off the carpet with ease. Because the tail skid is static, be careful to line up your takeoff straight in the direction you want the airplane to launch because you won’t be able to correct it much on the takeoff roll. In the air it is so lightweight that it feels like you’re flying a feather. In our office, it was able to glide from one end to the other at just under half throttle. It handles extremely well at slow airspeeds, just as it should. But its coreless motor has plenty of power to get the Mini Vapor moving pretty fast. Thankfully the large rudder can turn it around pretty quick, allowing you to be able to dodge obstacles or coworkers. I would warn you though, because of its small size and light weight, the Mini Vapor will react to even the slightest breeze generated by an open air vent or a person walking past it. This aircraft is no aerobatic performer. It is excellent in flying wide, slow circuits with just rudder and elevator. However, if you yank back on the elevator and pitch the nose nearly 90-degrees vertical, you can apply full power and hang it on its nose for a fair amount of time, using the rudder to keep it from

The coreless motor and 125 x 39-mm propeller give the Mini Vapor more than enough power to soar and speed through the air.

The 1S 3.7-volt 30-mAh LiPo battery mounts to the airframe in front of the control board but can be repositioned to shift the aircraft’s CG.

Thanks to its powerful motor and high angle of incidence in the wing, the Mini Vapor can execute high alpha maneuvers with ease. FOLLOW US ON TWITTER @RCSPORTFLYER

PARKZONE® MINI VAPOR BNF rolling over. And when it does roll over, you are able to quickly regain steady, level flight. Landing is super easy. With just enough power to keep the propeller turning, you can glide in for a silkysmooth landing. Thanks to its light weight and slow flying, you can land it just about anywhere. I was able to land and take off from our meeting table and even my desk!

CONCLUSION

The Mini Vapor is a blast to fly. It continues to underscore how enjoyable the Vapor series is and that speed isn’t everything when flying RC. Personally, I favor this over the fullscale Vapor because of how easy it is to fly in my home. I can remember flying the Vapor in the confined spaces of the hobby shop where I worked, and there we could barely manage to lift off and then dodge hanging products with it. Now that there’s the Mini Vapor, it would be

a breeze to fly in the shop. If you’re looking for something fun that you can fly anytime and anywhere, this is the fix you need.

Although the Mini Vapor isn’t an aerobatics aircraft, it can still be hovered for quite a while, considering its design.

The red-and-yellow scheme over the control surfaces makes the Mini Vapor’s sleek wireframe profile easier to spot.

DJI HOBBY FLAME WHEEL F550 PRO AN IMPRESSIVE HEXACOPTER WITH PLENTY OF POWER FOR PAYLOAD

oday, drones are appearing just about everywhere, and in many different roles—including being just plain fun to fly. Fixed-wing unmanned aerial vehicles (UAVs) are being used as hurricane hunters, geomagnetic surveyors, military

combatants and more. Multi-rotor aircraft are conducting low-profile surveillance and commercial aerial photography as well. The recent emergence of drone use has come after a boom in developments in aerospace technology and

information, and this is just the beginning. However, hobbyists have been flying “drones” for decades, albeit for recreation and private use. Multirotors are new to the industry and have adapted well to the simple The DJI Flame Wheel F550 Pro Receiver Ready is from Atlanta Hobby. It is an enormous amount of fun and has plenty of power too!

RC SPORT FLYER — MAY 2013

DJI HOBBY FLAME WHEEL F550 PRO need to fly that most public consumers have. A few months ago, DJI Hobby introduced a very capable performing hexacopter to the RC enthusiasts. It is an impressive machine that RC Sport Flyer will be flying this upcoming season, to get photos and video of airplanes all over the country. It promises to be lots of fun to fly too.

Completely assembled, the F550 top board and GPS unit are added overtop the bottom board and arms to form the rigid and lightweight airframe. All it needs now is a battery and some programming before flight.

The F550 performed perfectly during its test flight. The forward stick didn’t have to move far forward to make the model travel quickly to its target.

The Naza GPS unit is a fantastic accessory to the Flame Wheel F550 because of its accurate and sophisticated compass and positioning system. Be mindful to mount away from the propellors to avoid disrupting its sensors.

A Thunder Power® 4S 14.8-volt 5000-mAh 70C LiPo pack was used. It provides plenty of power to compensate for its weight and then some.

It is imperative that you have the hexacopter programmed properly and that its battery is centered over the model’s center of gravity. We recommend you do your test flights in an open field away from homes and people as a way to guarantee a safe setup and operation. Once you’ve rangechecked the radio system, you will initialize the motors by pulling both control sticks The leads must be held in position while the solder is down into the lower applied. We recommend using a hemostat to hold the right corners of the lead in place over the terminal. transmitter. The motors will then start to idle. After that it is just a matter of pushing the throttle stick forward to increase the power. Our hexacopter lifted off at about 25 percent power. Although, at this power setting it seemed to still want to hover in ground effect. By adding another five percent power, the model will get up out of ground effect and then stabilize very well.

We really like how well all of the components and their wiring fit in between the boards and without clutter at all. It really is an attractive hexacopter!

Not much solder is needed to mount the leads to the bottom board. However, you will want to be careful to hold the lead in place while the solder cools.

Because we had the arms on before we soldered the power leads to the battery and the VU, it became a two-man job, with one holding while the other soldered. RC-SF.COM

ASSEMBLY The DJI Flame Wheel F550 ARF assembles easily and quickly. The most difficult part of the build is soldering ESC and battery leads to their respective terminal points on the PCB—everything else is super simple to do. Note that no manual is provided with the kit. However, it is available to download as a PDF from the DJI website (dji-innovations.com), on the Flame Wheel downloads product page. Before the airframe can be built, you must solder the ESC leads to their respective terminals on the bottom PCB board. Be careful to keep it clean without excess solder spilling onto and burning the board around the terminals. Following that you must also solder the provided battery power leads and the Naza-M versatile unit leads to the front battery terminals. Next you will want to mount the Naza-M autopilot module, versatile unit and receiver to the bottom board. Use the adhesive pads provided with the Naza-M to mount the autopilot unit and the versatile unit to the center of the board—keep the F550’s center of gravity (CG) near the center of the airframe. We mounted our model’s receiver on the back end of the board using the excess adhesive pads. The F550 comes with extension leads that you’ll use to connect the receiver to the autopilot unit. The channel connections are different for each receiver manufacturer, but their wiring is outlined in the manual. The same applies to the ESC lead hookups and the gimbal servo connections to the Naza-M unit. With the F550’s electronics installed, you can begin mounting the motors to their respective arms. Each Twister 450 requires the propeller shaft to be mounted to the motor, and comes with the necessary hardware to do so. The motor will then mount to the outer platform of the arm, aligned to the hole pattern on the arm. Once mounted, the motors’ leads are then threaded through an opening in the arm and connect on the underside to their ESCs. The ESC is mounted to the bottom of the center of the arm. You’ll use the oriented to you relative to pitch, roll and direction. We painted the tips of our hexacopter’s blades red and white to help a bit with its orientation while in flight. You will be impressed with the forward speed of this machine. It is quite fast and yet you can stop it extremely quickly with a change in pitch. It will take some getting used to because the model presents itself in the air very differently than a typical helicopter. Also, as you yaw the hexacopter you must focus on its orientation, which is much the same as you would do with any other helicopter. What you’re going to enjoy about this hexacopter is programming it to do thing you would not dream of doing with a typical helicopter or 3D machine. You can program it to know where home—home being the spot where you initialize the controller and the ESCs. Then when you are flying the F550 at some distance from you, you can switch the hexactopter into “Home” mode and it will fly 72

hook-and-loop tape that comes in the kit. A simple trick to mounting the ESCs is to have the hooked half of the tape mounted to the arm and the loop tape to the bottom of the ESC. This will make the ESCs easier to remove or replace when necessary. With the arms and their hardware installed, you can then mount the Flame Wheel’s arms to the bottom PCB board—the screws are included in the kit. Before you mount the top board to the bottom board, you can loop the battery band through the slots on the top board. This will be a good time to power on and bind the receiver to the transmitter and run a motor test. This will affirm that all the motors are rotating in the correct directions and operating correctly, as outlined in the manual. It is also safer to do it now, because the propellers are not installed. Therefore you won’t have to worry about the model lifting into the air suddenly and possibly dangerously. Once done, you can mount the top board to the bottom. Before you mount the top board, select which inner arm you want to attach the model’s GPS unit to, and screw the mount brackets overtop it. Make sure the arrow on the GPS is facing directly towards the front of the model, and mount it to the top of the mount with the double-sided adhesive pad. With the GPS unit and top board screwed down to the main airframe, the Flame Wheel F550’s assembly is complete. You must now program the Naza-M unit. You must program into the unit the GPS coordinates and the receiver and transmitter settings before you fly your F550. You can download the Naza assistant software from the DJI website. Then follow the Naza-M manual instructions carefully in a step-by-step fashion to ensure your model will fly and stabilize properly in all its flight modes and conditions.

to its intialized position, doing so without your control inputs! Also, you can program this machine to go to a hover position and just sit there. So, if you want it to go to a spot 100 feet in the air, you must program it for the position you want it to fly to. Again, when you switch the hexacopter into that mode it will fly there and hover. In the next issue we will be adding the camera mount system. We’re going to give you a complete how-to of what it takes to turn this machine into a very stable camera platform for taking video of other models and such. What we’ve found so far is that this machine has lots of potential for fun in programming it, flying it, and taking lots of great still photos as well as exceptional video. Multi-rotor flying it just now getting momentum, but we think machines like the F550 are going to give it lots of energy.

Simplicity rules! It’s easy to like the Eraze. Once you snap the rudder in place, assembly is done. Like the fuselage, it’s molded from AeroCell foam, and just as light as it is tough… which is plenty. Everything else — including a punchy brushless motor and 12A ESC — is installed and ready for a battery. Dropping in an inexpensive 2S LiPo makes it fun; spending a few bucks more for a 3S pack turns turn it into a fast-moving blast. You have another choice, choice too. You can go with the RTF and get everything — or o go with the Tx-R radio and battery. Prime and ﬂy it with your own radi

500 3D BNF BASIC A HELI THAT TAKES YOU TO THE NEXT LEVEL IN PERFORMANCE

The Blade 500 3D BNF Basic is a powerhouse of performance and style. It carries an aggressive look to match its aggressive capabilities.

f you are like me, you like to fly all types of aircraft—gliders, airplanes and helicopters. You have a passion for one aspect of the hobby, but you like to fly all types of airplanes to keep your piloting skills honed. Moreover, you like the challenge of flying different aircraft quite simply because it is emotionally rewarding. Such is the case for me with helicopters. I started flying them a number of years ago, when the counter-rotator machines hit the market. After logging a fair amount of practice time on my simulator, I transitioned to conventional rotor helicopters but did not really jump headlong into the 3D machines. Honestly, they were just too intimidating for me. My paradigm has morphed over the last 24 months or so such that I’m now enjoying the unmatched challenge of flying 3D machines. I started by flying the heck out of a Blade 120 SR and then progressed to the mCP X, which was followed by the Nano CP X BNF. This was interspersed with lots of simulator time flying a high-performance 3D helicopter. Now I’ve started flying the Blade® 500 3D BNF Basic machine. It is an excellent transition machine for me, and I’m confident it will be for you too. Here is why I say so:

THE KIT

The Blade 500 3D BNF Basic comes completely assembled, with the exception that the rotor blades must be mounted—the blades are 425-mm carbon fiber composite. Blade is providing a limited-time offer of a set of 430-mm carbon fiber main blades for free when you buy a Blade 500 3D BNF Basic, so don’t wait! The Blade 500’s mainframe is 74

made of strong, lightweight carbon fiber that gives the machine a super rigid airframe that can withstand the rigors of extreme flight maneuvers. It also utilizes very high-quality CNC aluminum rotor head components

that are designed to stand up to the demands of 3D flight. The tail boom is a sturdy aluminum tube that the tail rotor’s drive belt runs within. Although the tail rotor blades are made of plastic, you can find upgrades

BLADE® 500 3D BNF BASIC

On top of comfortable handling and stability, the Blade 500 has a good amount of forward and climb authority. It doesn’t take much to get off the ground.

The Blade 500 3D BNF Basic comes installed with a Spektrum® AR6210 DSMX 2.4-GHz receiver that works well with the DX18 18-channel transmitter.

galore for this machine on the Blade website: bladehelis.com. Finally, your Blade 500 wears a very attractively colored Lexan canopy over the top of its impressive airframe. It gives the helicopter a look that says it’s ready for business.

IN THE BOX

The Blade 500 is packaged in a large cardboard box with protective foam partitions that hold the helicopter and battery pack. Where you will cut the tape to open the box, a label reads, “Warning: For experienced CCPM pilots only.” CCPM means cyclic/collective pitch mixing. Take this warning to heart because this is not a helicopter for beginners. Inside the box is an instruction manual.

Blade packaged their 500 3D in a sturdy and attractive box. Inside, the heli is well protected by two styrofoam halves that keep it in mint condition.

A number of accessories and parts are packaged with the Blade 500. These include two 425-mm carbon fiber blades, tools and hardware.

Nearly completely assembled and completely wired upon arrival, the model requires only that you install the blades.

The Blade 500 3D is built with a sturdy carbon fiber frame protecting the CNC aluminum rotor components and sports an aluminum tube tail.

RC-SF.COM

You’ll only really need the manual as a reference for programming your radio transmitter, which in my case is a Spektrum® DX18. The main rotor blades come packaged in a plastic sleeve, while the hardware and adhesive pads are in a separate sleeve in the box’s center. You must purchase the E-flite 6S 22.2-volt 2900-mAh 30C LiPo battery, a charger and at least a DX8 transmitter. If you plan ahead and get them all at once, you can put the battery on charge the minute you get the model home. In no time, you’ll be ready to bind the helicopter’s receiver to the transmitter and enjoy some exciting piloting!

Underneath the canopy on the aircraft’s nose is where the 6S 22.2-volt LiPo battery is housed. The battery is held in place by hookand-loop straps and tape.

Atop the rear of the airframe is where the G210 MEMS Heading Lock gyro is mounted. It provides excellent stability and head lock in flight.

• Servos S300 (swash); S400G (tail) • Hardware Allen wrench set, zip ties, (3) double-sided tape strips, Philips screwdriver, bind plug, main blade holder • Manual 24-page English edition

The CNC aluminum swashplate and rotor head provide a strong and lightweight assembly that can withstand the violent maneuvers of 3D flying.

The Blade 500 just needs to have its blades installed, battery charged and Rx bound to the Tx to get it off the ground and in the air. You can buy and fly in the same day!

BLADE® 500 3D BNF BASIC

A pair of Spektrum® S300 Digital Standard servos are mounted in the front top of the airframe. They control the aluminum swashplate.

A powerful E-flite® 520 brushless helicopter motor is housed in the airframe. The Spektrum AR6210 receiver satellite is positioned behind it.

So, when you hit the collective your Blade 500 helicopter is going to take off! I got mine into hover and delighted at the responsiveness of its controls in pitch, roll and yaw. Its forward flight speed is good, as is its rate of climb. After putting only about 10 minutes on the helicopter I was pilot spent and ready to hand the Blade over to my friend Marcus Hubbard—he is an experienced 3D helicopter pilot who would actually push the machine to see how it really flies. As you read in the build report, Marcus tweaked the setup of both the radio’s pitch curve and the swashplate on the helicopter. Then

IN FLIGHT

Because our Blade 500 3D BNF Basic came as such—Bind-N-Fly—I flew it as such for its maiden flight. You need to know I’m not a full-on 3D pilot. Honestly, I’m just learning how to hover RC helicopters inverted, which I’m mostly doing on Soaking up some of that warm desert sun, the Blade 500 hovers in front of the camera. The E-flite G210 gyro provides excellent head locking for this 3D machine.

Marcus inverts the Blade 500 for some performance-testing 3D flying, which demonstrates the 500’s maneuverability, control response and inverted flight capability.

Marcus rolls the Blade 500, revealing its undercarriage. Towards the rear of the aircraft you can see the servo and gyro leads running to the Spektrum AR6210 DSMX receiver.

we pumped more electrons into the LiPo pack. It took only 1620 milliamps, which relates to how much the pack used during one of my fiveminute flights. If you were push the Blade 500 3D harder I’m sure the pack would be depleted more. With Marcus at the controls, the Blade 500 3D jumped right into a nice steady hover. He then took it high enough to be able to flip it over and fly it inverted. Again, the machine delivers good, steady performance. Next Marcus rolled the heli while I got some photos. Marcus says it has good roll rate and is responsive to the setup we had programmed into the DX18. The heli loops well too. It seems to be more than capable of doing tic-tocs, funnels, chaos, tumbles, tailslides, etc. And, while this is not a flybarless helicopter, E-flite does offer an optional accessory to turn it into a flybarless machine, which should add to its performance even more.

HANGAR DEBRIEF

Priced at just $599.99, the Blade 500 3D BNF Basic is an absolutely excellent buy for pilots like me who are transitioning into flying 3D machines. It comes with everything you’re going to need to get into a 3D helicopter. You need only buy a 6S LiPo pack and use one of your You can’t help but be impressed by the power, performance and control authority that you can get with the Blade 500. It is one great flying heli!

I’m using one of the new Dynamite Passport Duo 400W chargers, and it is a great match for the 6S pack. Altenatively, you would do well with the Dynamite Passport UltraLite 50-W charger. The bottom line for me is that the Blade 500 3D is a perfect machine for pilots like me to fly when progressing into a 3D machine. It is affordable, durable, well made and easy to set up, and it flies extremely well for a 500-size helicopter. I’ll end by reiterating the warning on

ASSEMBLY What assembly? You’ll be happy to know that 99 percent of the assembly of the Blade 500 3D BNF Basic is done at the factory! The only thing you’ll need to assemble and install is the main rotor blades. Note, you will tighten the bladegrip screw until the blades remain horizontal when you hold the helicopter’s tail boom with it nose hanging down—not tighter and not any less tight, just enough! Installing the blades will take five minutes or less. The screws and such are provided. We found that the aluminum swashplate was not set at exactly zero pitch angle for the main rotor blades as it came from the factory. So, my friend Marcus and I took a few minutes to tweak the helicopter to get it set properly. You’ll want to use a blade incidence gauge to check that the blades are set to zero degrees FOLLOW US ON TWITTER @RCSPORTFLYER

angle of attack with the collective stick at its center position. Also, the helicopter was ever so slightly nose heavy. If, however, you upgrade to carbon fiber tail rotor blades it should bring the helicopter into perfect balance. To program the DX18 for flight we used the DX8 template as a guide. That template is found on page eight of the user manual. If you too are using a DX18 transmitter you can download our template at: rc-sf.com/spektrum. The file name is Blade5003d PG.SPM. Other than that was called out above you’ll only need to charge the E-flite 6S 22.2-volt 2900-mAh 30C LiPo pack. Oh yeah, take a couple of quick simulator flights to tone up your reflexes for the maiden of this machine.

Ace the Black 8

Hangar 9 Messerschmitt Bf 109F-2 60 ®

The goal given to Messerschmitt was clear—fit the most powerful engine available into the smallest possible airframe to produce a pilot’s fighter with the lethal ability to execute violent maneuvers no opponent at the time could match. Of the many Bf 109 variants, the streamlined “Friedrich” series was historically viewed as the best all-round fighter of the breed. ®

The Hangar 9 Messerschmitt Bf 109F-2 60 brings to life the nimble aircraft Otto “Bruno” Kittel used to help earn him one of the highest kill records in world history. The wing of the 60-size “Black 8” incorporates two Selig airfoils, as well as just the right amount of washout so that you can groove at high speeds, yet settle in for graceful landings. Its all-wood structure features construction methods that allow complex curved areas to be fully sheeted, which makes the airframe not only as light as possible, but is also an exceptional complement to the accurate scale outline. Other scale details include operational four-section flaps and the option to add E-flite electric retracts specially engineered to raise your warbird experience to ace-level. ®

Whether you’re a sport modeler or a die-hard warbird fan, the Hangar 9 Messerschmitt Bf 109F-2 60 is the fighter experience you’ve been waiting for.
