OK.  That helps a bit.  So if a plane is built with a Flapperon setup instead of an Aileron setup, how do you drop both to act as a flap or only one to control the roll axis?  It's kind of hard to explain isn't it?  But say for a mode one setup with flapperons, if you move the right stick to the right, won't that only move the right aileron and the left stick only move the right aileron?  So how do you move both at the same time to act as a flap?  Or can you only set the plane up to do one or the other?
