Ailerons on seperate channels exist on most Futaba gear up from the FF7, ailerons are controled on ch 1 and 6 (or 7) this allows flapperons to be controled from either a switch or the side slider on the FF9 and Zap, you can also programme ailivators from ch 2 and 5 to control the elevators as ailerons, at slow speed the advantage is that you still have prop wash over the tail and therefore some lateral control at a very slow approuch into a manouver or landing, at high speed the extra movement at the rear of the fus allows more controled flight with less coupling in pitch, flapperons can move both alierons up at the sime time as elevators down to increase pitch control (and visa versa) or both alierons can be moved up independently of the elevators to spoil lift at low speed and therefore increase desent angle as in a harrior manouver, or they can be both moved down to increase lift at low speed to decrease landing speed.
This is posted for information to those out there who may not know the available options on advanced transmitters and to inform them of what the experts use, which I am not one of, but I try everything my radio is capable of doing and use it on most of my aircraft.
