Bush Beast 3 electronics

Here is a video of me assembling the main electronics board used in my Bush Beast 3 RC airplane.

A Teensy microcontroller is used to read a decode an S-bus signal from the receiver and make all the servo signals. It manages servo mixing and gyro stabilization, as well as controlling LED lights on the plane.

More info about this, including schematics and code can be found on the Bush Beast 3 page here: Bush Beast 3 page

Two new airplanes

I got myself two new airplanes this summer at an RC plane auction that was organized at my local RC flying club FK Gamen.

The first one is a J3 Cub ARF model by Thunder Tiger with a wingspan of about 2.2 meters. The model came with a 4-stroke nitro engine that I have replaced with an electric power system. I will make a new landing gear with suspension and fix the motor cowling. I will probably add some kind of gyro stabilization also, this plane is surprisingly unstable in windy conditions.

The second plane is a Flair Magnatilla. The wingspan is about 1.6 meters. This is my first airplane with a nitro engine. A 4-stroke Saito. I will probably add a steerable tailwheel and make a few other adjustments over the winter.

Video: Bush Beast 3

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.

Li-Ion Batteries for flying RC models

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.

3D printed Spitfire

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.

My new glider

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.
