Not many people will argue with flying RC airplanes is super fun. One big bummer is when a crash damages a part beyond repair. Sure, the RC pilot could keep buying replacement parts but doing so will add up after a while. RC plane builder and general guy with a cool name, [HuckinChikn], decided to build a hot wire foam cutter so making replacement wings would be quick and cheap.
The actual hot wire part is nothing special, just some wire pulled taut across a frame and a 24 vdc power supply pumping out current and heating the wire so it melts any foam in its path. The unique part of the build is that one side of the hot wire frame is secured in place and only allowed to pivot about that point. The other side of the frame traces an airfoil-shaped pattern. This setup allows [HuckinChikn] to make tapered wings. The difference between a straight wing and a tapered wing is similar to that of a cylinder and cone.
Check out the video after the break for a quick demonstration how easy it is to make a wing when you have the right tool!

Flying RC aircraft with a first person view is the latest and greatest thing in the hobby. In a fact that I’m sure will be shocking to 90% of people, you don’t need to buy a Phantom quad fly FPV. The guys at Flite Test show how you can build a tiny 5.8GHz FPV transmitter for under $100.
The parts used for this build are pretty much jelly bean parts at this point, but [Peter] at Flite Test is going for extremely lightweight parts for this build. He found an NTSC board camera that only weighs 1g and added a wide-angle lens. The transmitter is a tiny 200mW module that only weighs about 2g.
Why are the Flite Test crew going for small and light FPV setups? They just launched a new line of planes that can be built from a single piece of foam board. If you have a small micro quad, you can easily add FPV to it with this rig.
Anyone can build a remote control airplane with a sheet of foam, some glue, and a handful of servos. Building an F-14, complete with the swing wing mechanism? [Thomas] found built one that’ll take you right into the danger zone.
This was [Thomas]’ first go at scratch building a RC airplane, and wanted a lot of electronics inside. His choice of airframe was the venerable F-14 Tomcat, complete with wings that swing out for landing and swing in for high-speed flight. This isn’t just taking off-the-shelf receivers and putting them in a fancy airframe, either: [Thomas\ is reading the PWM signals from the receiver with a small electronics board, mixing the elevons with his own code, and implementing an auto stabilization system with an accelerometer.
Most of the work on the airframe was done by [Maybz] over on the RCGroups forums. That’s an impressive thread spanning seven years of posts. [Thomas] doesn’t see his F-14 as an end goal, though: he’s using this as a stepping stone to learn about building unstable planes for a more complex UAV.

[Roballoba] decided to combine his love for RC planes, things that light up, and photography, and we’re glad he did. He shares his method in this Instructable for illuminating a bare styrofoam replacement fuselage for a Parkzone Stryker RC plane. There are many more amazing pictures there as well.
He used low-tack tape to lay out the LED strips on the fuselage, solder the connections, and test them. Once he was satisfied with the arrangment, he flipped the strips face down so the foam diffuses the light. The lights are powered by a 12V Li-Po battery he soldered to a deans connector. Finally, [Roballoba] covered and heat sealed everything with Doculam, a very cost-effective laminate that offers great protection and security.
He used some LED corn lights as afterburners, which is a nice touch of realism. There is a video after the break where [Roballoba] shows us the connections up close and then runs through some light show options. Another video of a nighttime flight is waiting for you in the write up.
Spent too much money on eggnog and a new console this year to be able to replicate this build? $30 will snag what you need for this smartphone-controlled paper plane we featured a few weeks back. You could always BeDazzle it.

Whatever candidate (if any) you’re in favor of, we could bet that you’re probably tired of seeing advertisements and political signs everywhere. [Mark] wrote in with a hack that allows you to actually use these signs for something fun, making a RC airplane!
[Mark] gives a full bill of materials in his article, but the featured component is campaign sign. This isn’t LawyerADay, so we’re not sure of the legality of taking them. After election day at least, it’s doubtful anyone will care. Of course you’ll also need a motor, prop, and RC controls, as well as some dowels to attach the tail section to the main body, so don’t buy the “campaign promise” that this is a free airplane.
CAD diagrams are available of the cutouts, as well as how to cut the signs to form hinges without any other parts. This is quite clever, and a video of the plane in action on a table is available on the site. According to [Mark], no video was rolling on its test flight, but it did fly before some interference grounded the plane. Hopefully he’ll be able to get some footage of it in action soon!
