The definition of a positive aileron deflection is when the right-hand aileron deflects according to the right hand rule - that is, trailing edge down (TED). Unfortunately, this results in a negative roll rate - it would be nice if our choice of coordinate system caused a positive aileron deflection to result in a positive roll rate, but this is not the case. :-(
Anyhow, yes, Tony wanted to control each aileron individually, so this was changed. It *should* *be* the same to you and I. It's just that the left aileron will get the negative of the right aileron deflection. A control system *could* use the ailerons as flaps AND as ailerons. These are called flaperons. The space shuttle uses the wing outer control surfaces as ailerons and elevator. These are called elevons. You might also combine flaps, spoilers, ailerons, and elevator and call it a slapevon. Well ... maybe not. ;-) In any case, Tony was right to split out the left and right aileron controls because we might want to model an aircraft that addresses various control surfaces in unique and interesting ways.
