Aridium, This is where the confusion is. Its not the deflection of the aileron that creates the drag, its the change in the camber line of the airfoil. Even at "0" AOA when you add aileron you now have an AOA because the camber of one wing will be positive and the other will be negative relitive to the fuselage datum line. At this point how much the difference in lift produced {it can be to the canopy OR the wheels at "0" AOA} is dependent on the placement of the wing on the side of the fuselage. The reason for this is that the airframe does not rotate around the center of the wing but around the center of balance. In a pattern plane setting the differential at true vertical with "0" AOA will compensate for the wing offset from the balance point only, this dimension does not change upright or inverted. You will still get yaw with AOA but you don't have to compensate for the airframe, only the AOA. I hope this helps, and I know its kinda weird.
