Hi !
I decided to start a new project at the beginning of the covid crisis: making a full scratch aircraft. I choose the bush aircraft Backcountry Supercub for its shapes
The beginning was quite tricky. I wanted to weld the frame, but Laiton and tin aren't really compatible, the global frame was really fragile, and some difficulty to get a symetric frame.
I wanted to get a model as realistic as possible. With real tires, functionnal flight control and actuators, and respect the structure of the real frame.
Actuator are made with spring. The main problem was the material resistance compared to the spring resistance. Here is the final result:
Flight controls were quite tricky as well. The main problem I had, was to find the neutral position and the yarn tension. At the end, the pitch and yaw controls are reversible, so i can by moving the stick make the rudder and horizontal plane move, but that's not the case for the ailerons due to high friction and the lenght of the wire
Flaps are controlled by a controller.
Cockpit:
Finally, the enfine, full scratch as well, and made only with styrene sheet and tubes. I choose the continental O-200. References were really easy to find on the internet
Next step, I have to add all the link between the engine and the controls, as well as every electrical wires. I also have to find a way to cover the wing. I tested the kraft paper, silk paper and aracover but for each one, the result wasn't really beautifull...
Do you have any other idea to cover the wing ? A special paper or something like that, adapted to small surface...
