The aileron wires are very hard to connect. You have to get the clevis to hook on the small piece of metal with the small hole in it that's tucked inside the upper aileron. After I connected them I noticed that the inboard side of both top ailerons rubbed the wing. I'm going to sand a little of the paint off between the aileron the the wing. Have you installed the engine yet? What engine will you be using? I'm going to use a Saito 150.
