Bush Beast 3 is an RC bush plane that I have designed and built during this winter. The plane is built using balsa wood and covered with Oracover. The design of this airplane a combination of Trent Palmer’s Kitfox, the Pilatus Porter, and various Cub planes.
I have made a custom electronics system on this plane. A Teensy 3.2 microcontroller reads the S-bus signal from the RC receiver and controls all the servos, it also applies 3 axis gyro stabilization and manages all servo mixing and a custom lighting system. More about that in a future video.
I fly my RC Airplanes and quadcopters on LiPo batteries like most other people. But LiPo batteries have several disadvantages. The biggest problem is that their life is pretty short. They usually don’t last more than 100 cycles. Therefore I wanted to explore the possibility of using 18650 cells to power my RC models instead. I while ago I got myself a cheap battery spot welder from China and a couple of genuine LG HG2 cells.
Here is a short video of a fully 3D printed Spitfire. Design by 3DLabPrint. The plane is printed by a friend of mine, on his Original Prusa MK2 3D printer. It was an interesting experience to build it and test it. Usually, I am not a big fan of scale RC models at all. The plane is a little heavy for my taste, and maybe my setup is a bit underpowered. But it does fly nicely, and it does look very cool in the air when the light shines through the wing, highlighting the 3D printed reinforcement structures.
I bought this airplane used from a friend in my local RC flying club a few months ago. The model is a Windstar from Thunder Tiger. It is a three channel electric glider with elevator and rudder. The wingspan is about 2 meters. The airplane was old and used a lot. I started by removing all the covering film and replaced some broken wood parts. I rebuilt the nose of the fuselage to fit my needs with a large magnetic battery hatch. I also modified the wing tips and removed the original plastic ones and replaced them with balsa wood. After all repairs and modifications was complete I covered the airplane again using a Oracover, yellow and red on the top side and black on the bottom.
This video shows the first few flights of a new balsa airplane that I have designed and built during this winter.
The airplane has a wingspan of 90 cm and weighs around 700 grams including battery. I use standard RC equipment, no special functions or microprocessors in this one. I built this airplane just to havs something unique and fun to fly with. The plane is built using traditional building techniques. It is built out of balsa and covered using Oracover.
Last year I designed the “Stick pusher” for indoor flying. This years airplane is new design. I took all the things that a liked with last years airplane and added some new features, ailerons being the biggest change. I have also moved to a twin boom pusher design to be able to have the motor and propeller more in the center of the air frame, this removes the effect that airplane wants to dive when you increase the throttle. It also makes the airplane fly more symmetrically. The airplane has large control surfaces and is capable of tight loops and turns. It has a relatively large speed envelope for being a small indoor plane, it is possible to fly quit slow, but it can also fly very fast if you want.
