With many of today’s giant scale aerobatic aircraft multiple servos are often used to move each flight control surface. Modern computer radios actually have specialized menus to help setup and adjust multi-servo installations, but you can do it the old fashion way as well by using programmable mixes. Basically you setup a two servo setup (for ailerons for example,) and then you mix the left and right servo channels to two other auxiliary channels ending up with two servos controlling each aileron surface.

01

But to fine tune you setup, you need to make sure that all of the servos attached to the same control surface don’t fight against each other. You do this by first carefully adjusting each servo’s end points and the center positions until the two aileron servos move in unison. You can check for a proper setup by reading each servo’s current draw.

HAN172-450   meter

To do this, you can use a “Digital Servo and a Current Meter” from Hangar 9. Reading the actual servo draw you can find easily find mismatched servos and binding linkages.

08

Another way to measure servo current is to use a common digital multi-meter. But first you’ll need a way to connect the meter between the servo and the receiver. To do this you’ll need: a set of test probes (that plug into the multi-meter), a soldering iron and solder, wire cutters, a wire stripper, heat-shrink tubing, and a 12-inch heavy-duty servo extension.

Feature of the Month

 

Here’s how I made my patch harness.

1. Cut the power red wire on a 12-inch heavy-duty servo extension and strip back both ends of the wire approximately 1/8-inch.

2. Clip off the test probe from each wire and strip back both wires approximately 1/8-inch and tin all the wires.

3. Solder the red power line on the female connector to the black ground test probe wire that will plug into the multi-meter. Use heat-shrink tubing to cover the solder joint.

4. Solder the red power line on the male connector to the red power test probe wire that will plug into the multi-meter, again covering the solder joint with heat-shrink tubing.

5. Turn the multi-meter on and select the proper current setting.

6. Plug the servo into the female connector of our custom harness and plug the male connector of our custom harness into the correct port on the receiver.

7. Power on both the transmitter and aircraft and see the current draw. Make any necessary changes in the linkage setup to decrease it. Ideally, this number would be as close to zero as possible.

The world’s most iconic B-17 Flying Fortress is nearly ready for her long-awaited unveiling, just in time for the 75th anniversary of her final mission. Memphis Belle, an early-model B-17F, was flown by the first 8th Air Force crew to complete 25 missions, earning pilot Robert Morgan and his crew the honor of returning stateside for a morale-building war bond tour.  The aircraft and her crew gained added fame from a 1944 wartime documentary directed by William Wyler, and decades later a 1990 motion picture reintroduced the stirring story to a new generation.

On January 4, 2018 the United States Air Force Museum hosted a media event at the restoration hangar to showcase the latest progress in a 13-year project to restore and preserve Memphis Belle for display in the museum.  The project began in 2005, and no effort has been spared to return the famous aircraft to her wartime condition, using original components and materials wherever possible.  During the restoration, repairs of battle damage and other modifications were uncovered, including an entire vertical stabilizer that was grafted on to replace the heavily-damaged original.

With the airframe work completed, the restoration crew then spent two months repainting the Belle using historically accurate paint formulas.  They were aided in this effort by the existing archival color footage from William Wyler’s documentary.  His crew shot more than 11 hours of color film, and all of it was available to the restoration crew, along with a wealth of color still photos.  The restoration is incredibly detailed, and many missing parts were fabricated from scratch, including a glycol heater completely hidden in the left wing.  This shows the thoroughness of the restoration, even for components that will never see the light of day.

Museum curator Jeff Duford explained that in many ways the Belle was an ideal restoration project.  Flown by the first crew to complete 25 missions, she represents the heavy sacrifice paid by early-War 8th Air Force aircrew, during a time when the odds were 3 in 4 of a crew not completing their tour.  Also, the wealth of archival information on this particular aircraft made it much more practical to make the restoration absolutely accurate.

Memphis Belle will be the centerpiece of a three-day special event this spring, culminating in a May 17, 2018 unveiling marking the 75th anniversary of her final combat mission.  The Belle will be home at last.

Here’s a golden oldie from back in 2012. Flying at the popular Big Biplane Bash RC Fly In, the coveted Best of Show award went to an amazingly large, Monster Scale Fokker Triplane. Hosted by the Central Connecticut RC Club, the BBB event awared Ken Eckstein the award after he put in several amazing and very scale-like flights with his Triplane.

(Above) Gerry Chats with Ken about his Monsterous Triplane.

IMG_1662.jpg

From New Milford, CT., Ken’s Fokker Dr.1 is the biggest biplane that has ever flown at the event, and it is certainly the bigger I have ever seen fly. Ken’s triplane was built from Nick Ziroli plans and was enlarged up to a massive 45% scale! Ken powered his triplane with a 3W 150cc gas engine and covered the plane with fabric and painted it with latex paint. The plane has a 11ft., 2in. span and it weighs in at about 100 pounds!

IMG_1749.jpg

Seeing the big triplane fly was really amazing and it had a perfect airspeed and flew patrol over the flying field looking exactly like the full size WW1 fighter. If you have never seen a real triplane fly (like at the Old Rhinebeck Aerodrome) then Ken’s monster is as close as you can get! It was simply great!

From Esprit Tech:
When it came time to design a pilot for the new Backpack M3, Opale knew that they were going to need to start from the ground up. The mechanical constraints, resistance of the materials, and the pilots’ behavior take on a whole new dimension when it’s being designed to handle a 2-3m wings.

A pilot this realistic requires a harness with the same quality standards. The geometry has been optimized to achieve that highest possible pilot flexibility with the most convenient installation methods. All of the straps are easily unclipped, making installation of Ben much easier than ever before. You can equip the Ben pilot with optional Speedbar function that allows you to slightly adjust the leading edge of the wing by pulling the A lines of the risers. This changes the angle of attack of the wing and allows temporary improvements in wind penetration.

The stall, or more accurately the inadvertent stall, has probably caused more RC planes to crash than any other cause. The safety of your airplane depends on your knowledge of its slow-speed handling and stall characteristics. To minimize the number of crashes due to stalls, the pilot must understand the principles of what makes a plane fly and how to make practical use of the information.

First, we must understand how the wing supports the plane in flight. As the plane moves through the air, the amount of lift is determined by the particular airfoil and its angle of attack (AOA). The AOA is the angle formed by the wing’s chord line and the oncoming airstream. The other primary factor in the amount of lift is the speed of the airfoil through the air. A stall will occur when the AOA exceeds the wing’s critical angle of attack. At this angle, the lift suddenly decreases and the drag increases, resulting in the plane losing altitude very rapidly. The pilot has control over the AOA with the elevator. For example, if the pilot inputs up-elevator the tail drops and the nose rises, which increases the wing’s AOA. An important point to note is that the plane can be moving in any direction, including straight down, and a stall will occur if the AOA is exceeded.

The only way to recover from a stall is by decreasing the angle of attack below the critical angle by pushing forward on the elevator. By learning your plane’s slow-speed and stall behavior, you should be able to avoid getting into an unintentional stall situation in the first place. Take your plane up high; reduce the throttle while increasing the elevator deflection to maintain your altitude. As it slows, note how the plane reacts to your control inputs, and when it does stall, note if a wingtip drops or if it stalls straight ahead. Recover from the stall by lowering the nose to gain flying speed. Adding power will speed the recovery and minimize altitude loss. Practice this until you can recover with the wings level. All models stall differently, so you’ll want to learn your model’s characteristics.

Spins are an exciting aerobatic maneuver when done intentionally, but an unintentional spin close to the ground will spoil your day. A spin cannot occur unless the plane is stalled. If at the moment of stall there is a yawing moment, an autorotation will commence. The spin is caused by a complex series of events. If rudder is applied as the wing stalls then it will cause one wing to drop. For instance, if left rudder is applied with up-elevator, the left wing will move downward and rearward resulting in a left roll. The left wing will therefore have a greater angle of attack and slower speed relative to the right wing. The right wing will essentially be less stalled than the left wing resulting in autorotation about the spin axis. In the fully developed spin, the aerodynamic and inertial forces are stabilized into a predictable pattern of rotation. The rotation, airspeed and vertical speed are stabilized and the descent path is vertical. Unless something is done, the spin will continue.

Turns in the landing pattern can lead to spins if a skidding turn is attempted. A skid is when too much rudder is used for a given bank angle. Often a pilot will use rudder when overshooting the turn in order to avoid a steep bank angle. This is the recipe for a spin. If you find yourself in a spin, most planes will recover easily by letting go of the controls and letting the speed build up. Some high-performance planes require opposite rudder and/or down-elevator to recover. Use caution during the recovery as the speed can build up quickly. Also, avoid a secondary spin during the recovery by not using excessive up-elevator. Every plane has its own peculiar spin characteristics, so make sure you try spin recovery at high altitudes.

When it comes to moving surfaces and other articulated parts on your RC airplane requiring a really long stroke, the Actuonix L12-R, L16-R, and PQ12-R series of linear servos operate as direct replacements for any standard analog rotary servo. Using standard 3-wire (ground, power, and signal) connector leads, there are 21 models of RC linear servos for use in any RC project. Designed to work with typical RC receivers and battery packs, they are also compatible with Arduino control boards, VEX Microcontrollers, and many other similar control boards designed for robotics. The L12-R series is the standard range of micro linear servos, and they come in three stroke lengths (30mm, 50mm, and 100mm) and three gearing options, for moving forces between 2 and 17 pounds. Priced at $70, the L12-R actuators are ideal for moving scale canopies, doors, drag flaps and spoilers, or other scale functions where a standard servo setup can’t provide the required power and stroke length.

It’s always interesting to see the diverse interests of those involved in building and flying giant-scale aircraft. Some RCers are involved completely in aerobatics, while others focus on building exact scale versions of full-size subjects. No matter what  interest have, care and caution must be taken while building your model airplanes. Aside from proper building materials and making structurally sound glue joints, it is equally important to produce a straight and true airframe for your airplane to perform as intended and stand the test of time.

giantscale2

Having a straight airplane is a must, as no computer mix can completely compensate for a badly warped airframe. The straighter an airframe is, the more neutral it will be while flying. I can honestly say that I have had many airplanes that only required a few clicks of trim (with minor changes to the CG), and I owe this to proper building and alignment.

My recent project is a Super Decathlon from Exclusiv Modellbau, and it features a two-piece, 132-inch wingspan and is a rather complete wood kit intended for an experienced builder. Using the Super Decathlon as an example, let’s focus on the proper alignment between the horizontal and vertical stabilizers in relation to the wing. Of course this can be applied to any giant scale airplane you are building…

From Futaba:
The Futaba Air Team is proud to add pilot Colton Clark to its growing roster. Colton has been impressing airshow crowds with his incredible flying skills for 20 years. He inherited his love of RC flying from his father (Wayne Clark), who took Colton to the field after he’d spent time on his flight sim. Within a few flights, he was piloting .40-size glow planes solo.

Colton caught the 3D bug after he saw a video featuring World Champion Quique Somenzini. After many years of 3D, he grew interested in mastering other areas of flight, like making RC aircraft more realistic-looking. Appearances at events like Joe Nall and the AMA East & West made Colton a familiar name to flight fans. In 2017, Colton stunned spectators with a series of night 3D flights at the EAA AirVenture in Oshkosh. No matter where fans see him fly, they’re always in for one heck of a show!

As you can expect, it’s hard for Colton to pick a favorite plane. “My favorite RC vehicle is whatever’s on the other end of the transmitter I’m holding. Having a trainer, sporty flying foamy, large 3D aircraft, sailplane and high-speed aircraft in the hangar gives me a fix for any type of flying I want to do. My biggest drive in the hobby is to pass on knowledge and help get more people in the air with the best results,” says Colton.

Please join Team Futaba in welcoming Colton, and look for him at RC events all season!

From Hangar 9:
Packed with firepower, fast and heavily armored, the mighty Republic P-47D Thunderbolt could complete virtually every task the U.S. Army required. WWII pilots called it the “Jug” for its massive size and bottle shape. The enemy knew it better as the “Juggernaut” because it dominated the skies as the toughest and hardest hitting foe ever encountered. The all new Hangar 9® P-47D Thunderbolt 20cc ARF takes the popular warbird a bold step further. No stranger to making a great flying P-47D model, lightweight, laser-cut construction combines with expert craftsmanship to bring a durable, all-wood airframe with incredible realism and great performance. The result is a model replica that’s a blast to fly and looks as though it belongs in a museum. Highlighting its outstanding appearance is a rich film covering with incredible detail and a satin finish. Stunning only comes close to the description of how the intricate panel lines and soft color transitions take this iconic warbird to deeper level. Plus, it’s easy to maintain and durable. Multiple nose-art decal options included let you personalize the model to your own liking. Whether the P-47D Thunderbolt 20cc is your first warbird or a new addition to a growing fleet, don’t be surprised if a Hangar 9 warbird is all you’ll ever want to fly.

Scale Detail

Beyond the factory applied satin-finish printed covering, other iconic details include a dummy engine, wing cannons and bombs, gear doors, radio antenna and a painted pilot figure, just to name a few. Choose from one of the three nose-art decals included to finish your model off.

From Esprit Tech:
The Fokker Eindecker fighters were a series of German World War I monoplane single-seat fighter aircraft designed by Dutch engineer Anthony Fokker. Developed in April 1915, the first Eindecker (“Monoplane”) was the first purpose-built German fighter aircraft and the first aircraft to be fitted with a synchronization gear, enabling the pilot to fire a machine gun through the arc of the propeller without striking the blades. The Eindecker gave the German Air Service a degree of air superiority from July 1915 until early 1916. This highly prefabricated kit belongs in the “Super Scale Competition” models category. Once built, the airframe is extremely light and clean but still able to withstand the high loads and stresses associated with aerobatic flight. The manufacturer uses the latest construction techniques including Laser CNC cutting to achieve high strength and low weight. Each part and every detail are meticulously made.

Finally true to scale, faithfully structurally reproduced model. Flies exactly like a real airplane. Selected premium quality balsa and plywood. All the parts interlocked together for easy and fast building. Just assemble and then glue parts together.

Special Features:

  • Control surfaces: Ailerons, Elevator and Rudder
  • All balsa/ply built-up construction
  • Fully illustrated instruction manual
  • Laser cut interlocking structure
  • Scale wire landing gear
  • Interlocking parts for easy and fast building
  • Just assemble and then glue it

From International Drone Racing Association (IDRA):
The International Drone Racing Association (IDRA) has announced that it has condensed its liability insurance for drone pilots into a single policy that has no drone limit, no deductibles, and maintains the worldwide coverage that has greatly benefited IDRA members. Starting January 1st, drone pilots can purchase the $1 million policy for $265 and will receive their certificate of insurance within 24 hours. The policy is valid for 1 year, covering all potential liabilities from recreational flying, racing, and training, if the drone pilot adheres to IDRA’s Safety Manual and complies with the Legal Regulations in the area the pilot is operating. The IDRA community has upheld a high standard of safety and compliance, experiencing zero claims throughout the year of 2017.

The announcement comes one year after IDRA’s launch of the first primary liability insurance, with worldwide coverage, for drone pilots and recreational hobbyists. The $1 million policy was offered to IDRA members, whom predominately reside and operate internationally. In the past four months, IDRA experienced a 336% increase, 60% of which accounted in September, of insurance policy and membership sales. The only downside to the policy was that it was structured around the number of drones a pilot operated; the more drones the more expensive it was to purchase. To IDRA and the insurance program’s designer, Chief Financial Officer Bonnie Haggerty-Leister, it was clear that the policy needed to be revamped to better fit the community’s needs.

“I’m extremely excited that we are able to release this new policy for the international drone community,” said Bonnie Haggerty, CFO of IDRA. “My team and I negotiated for many months with several underwriters and our partner, Avion Insurance, to structure this simplified liability policy for drone pilots around the world, with the purpose of being more applicable and affordable to meet the demands of IDRA’s growing member base.”

UAS/Drone racing is a worldwide sport that utilizes Unmanned Aircraft Systems (UAS) and Virtual Reality (VR) technology to allow a new breed of innovators to compete on the international stage. There are roughly 100 drone competitions in the U.S. annually and 200 worldwide competitions, highlighted by races like 2016 World Drone Prix in Dubai and 2017 Dover Internationals at the Dover International Speedway with NASCAR. In 2018, IDRA will feature several marquee races at partnered events and venues like South Point Hotel & Casino in Las Vegas, Dutch Comic Con in Utrecht, University of Phoenix Stadium in Glendale, AUVSI Xponential in Denver, Munhak Baseball Stadium in Incheon, and Dover International Speedway in Dover, with the projection to exceed 200,000 spectators over the season.

Neodymium magnets are members of the rare earth family and made from a combination of iron, boron and of course, neodymium. They were developed by General Motors and Sumitomo Special Metals in the early 1980s and are the strongest permanent magnets to date.  These magnets are truly amazing. Their strength is over ten times the strength of the best ceramic magnets.

Magnets1

They can easily be purchased in many different shapes and sizes, spheres, discs, cylinders, blocks, rings, etc. and are graded by the ingredients they are made from, using the letter designation “N” followed by a number.  As a rule, the higher the number the stronger the magnetic properties.

Here are some of the supplies needed:

Whats_Needed

Since I was in the midst of converting my 1/4-scale Me-163 Komet from glow to electric power, it was the opportune time to redesign the cowl mounts from unsightly exterior screws to internal magnets.  My Komet has a wingspan of 82 inches, weighs in at around 12 pounds and has a round, cone style cowling that is approximately 7 inches in diameter at the firewall. The cowl is fiberglass and very lightweight. For the Komet I decided to use ¼ inch diameter by 1/8 inch depth, N42 rated, cylindrical magnets.

Here’s how I did it.

1.  Make a cowl mount former using 1/8 inch light ply.   The former should be ¾ inch to 1 inch wide and slightly larger than the firewall diameter.

1

2.  Temporarily mount the cowl former to the firewall using whatever screws you like.  I used hex head servo mounting screws because it’s easier to use a ball driver than a screwdriver.  Next, use your favorite sanding block to sand the outside edge of the former to conform to the fuselage. Test fit the cowl to make sure it fits nicely over the former and fuselage.

2

3.  Mark the former where the magnets are to be installed. In this case, I marked 13 locations around the former. There was no particular reason for the number 13 other than I thought more would be better than less.  I then drill out the locations using the appropriate size drill bit.  Since I was using ¼ inch diameter magnets, I used a ¼ inch drill bit.  I wrapped masking tape around the bit to use as a depth gauge so that I would not drill any deeper than needed.

3c

4.  Drill out the magnet locations.  Remove the former and install the magnets into the firewall using your favorite glue. I used medium CA to install mine.  It is not important which field of the magnet remains exposed, positive or negative. Make sure that the magnets are flush with the firewall when permanently installed.

4

5. Install the corresponding magnets in the cowl former.  It is vitally important that these magnets are installed with the correct pole facing its opposite on the firewall.  To accomplish this, just place the magnets over the corresponding magnets on the firewall.  Don’t worry about magnetic fields here, the little buggers will snap to its opposite as you draw near. Place the former over the magnets, apply some glue and tap the former down against the firewall to seat all the magnets in the cowl former. At this point you have all the magnets in the cowl former and firewall permanently installed.

4b

5b

6.  It’s time to adhere the cowl former to the cowl. Pry the cowl former off the firewall.  Use Glad Cling wrap to cover the firewall and fuselage from excess glue used to install the cowl. Cling Wrap is thin, will stretch to make a good seal. Use some masking tape to pull the cling wrap tight. Once the Cling Wrap is installed, put the cowl former in place over the cling wrap. It will snap right in place.  Use your favorite epoxy to glue the cowl to the cowl former.  I dabbed the outer edge of the cowl former with epoxy and ran a bead inside the cowl.  Adjust the cowl in place and tape securely.

6

  1. When dry, pry off the cowl, remove the Cling Wrap, you’re all done. Your cowl  should snap tightly in place.

7

This  shows the model primed with the cowl installed.

The painted and finished electric powered Komet.

10

Of course, the size and number of Neodymium magnets used will depend on the size and weight of your particular model.  Suffice to say that I believe any model in the .40 to 1.20 range could utilize the same size magnets that I did for the Komet. You would only vary the number used based on the size and weight of the cowl.  For larger models, I would consider using the larger 3/8 or ½ inch cylindrical magnet.

Magnets2

Where to buy.  The best place I found to purchase Neodymium magnets in all shapes and sizes eBay.  The number of eBay listings is staggering and the prices are very reasonable.

You’re working on a model and you need to drill the cowl to match pre-drilled holes in the fuselage, but you can’t access that area once the cowl is in place.

 

The Solution: Grab your masking tape, pin, marker, drill, cowl, and fuselage then follow these easy steps.

1.

2a

Lay the masking tape (I used painter’s low tack tape) over the area where the pre-drilled holes are. Put your cowl temporarily in place to be sure the tape extends past the rear edge of the cowl. If it doesn’t, just use wider tape or add a piece to the first. Use a pin or marker to mark the tape over each hole’s position. With this plane, I was able to reach inside the front and push a pin thru as long as the cowl wasn’t in place. Once you’ve marked the holes, slide the cowl in place and draw a line down the back edge of the tape where the cowl ends. Make some index mark so you can place the tape perfectly on the cowl in the next step. I used the bottom edge of the fuselage/cowl.

2.

3a

Remove the tape carefully from the fuselage and place it over the outside of the cowl, carefully lining it up with your edge line and index point.

3.

4a

Once your happy with the placement of the tape, drill the holes where they are marked on the tape. Remove the tape and slide the cowl into place – it should be perfect.

4.

5a

Sit back and admire your perfectly fit cowl on the finished product.

Now with the cold weather outside, is a great time to pull some fuel tank maintenance. To get the best possible performance from your glow and gas powered airplanes, you have to properly install and maintain your entire fuel system.

tanksFrom assembling and installing the tank itself correctly (with foam padding), to installing  in-line filters and other fittings, you want the fuel system to work as intended so your engine will have an uninterrupted supply of fuel.

 

 

filtersThere’s a lot you can do to keep the fuel flowing and making sure you engine gets what it deserves, a clean fuel supply. Filters are one of the basic ingredients every plane should be equipped with.

 

 

 

 

Here’s a great Du-Bro video showing some of the basic Fuel system accessories  to consider.

This disassembly and reassembly video from Academia Motor may just be the best thing you’ve watched yet in 2018 — really! Some internet sleuthing shows that the Graupner-O.S. Wankel .30ci powerplant was the world’s first model rotary piston engine. A collaboration between Graupner and Ogawa Model Mfg. Co. (O.S.), it used Felix Wankel’s design with a rotating triangular piston in an epitochoidal shaped chamber. It was first marketed in 1970 with a price tag of just $87.50!
