Flaperons on barndoors (inset) ailerons vs strips? Dunno, all I know is what the glider guys do, and that is flaps on the inner panels, going down and crow on the ailerons, going up. Both are for drag control. If you was to try anything on the inset type it would have to be in an up sense only, as with sufficient down you could stall the tips at any speed. Strips? Can't see any advantage, better to have separate flaps and ailerons. Do some of us fly full size? Bears do stuff in the woods? I detect some old PPL's in this forum...
