Mike: what a cool collection of these devices! I guess it's all about the craft of miniaturization in trying to incorporate all the full size stuff. How far can we be from a true 'fly by wire' system. I think the flaps would be easier to model than, e.g., movable slats. Thought about that for my Skyray, but I understand they welded those shut in the full size as they were problamatic in a dogfight-had a habit of sticking open, I guess. The 'tailerons' or elevons I think differentiate the aileron function from a stabilator or 'all moving elevator' which functions only as an elevator. I'll have to spend some time digesting Mike's info.
