After much trial and error I propose this drawing of an ultralight Part 103 that can be motorized with an electric motor as well as with a gasoline engine. The weight and balance of this plane is better than in my previous projects. But the wing folding system with rod ends remains the same, I think this unique process is worth trying. This plane can be towed by a car without the need for a trailer, provided it is equipped with adequate wheels.
