Maybe its also a solution to buy an Eachine GA202 from banggood for under 20 bucks. You get the glider, transmitter, a gyro receiver board, two motors and two batteries. If you strip the electronics, it’s all you need for two channels.
Oh and the C17 Transporter is there too, it’s shown for 32 bucks for me at the moment. Guess I will just buy it and strip the electronics to start my ez journey 😄
