Default Re: Aileron size

How fast is it going to go? What's the wing loading? What airplane is it? What do you want the airplane to do? All of these determine the size of the aileron; there is no one answer. Try to find something with similar characteristics and copy that.

If it's a high wing that used to be 3-channel, use lots of aileron differential (more up movement than down). Equal throws will probably result in adverse yaw due to higher induced drag on the outside/up wing, leading to aileron ineffectiveness or even reversal. Also mix some rudder to ailerons (start with about 10%).
