I have a Kyosho GeeBee-Z and a 6-channel JR radio (JR-662). The plane calls for 4-channels, with 5 servos (a servo for each aileron). Could I simply plug one of the aileron servos in the 5th or 6th channel and have the two ailerons work as flaps when needed, at the flip of a switch? I'm assuming there's a function for this on my radio.

Also, if I do this, i.e. flip the switch and have both ailerons move down as flaps, would I be able to have ANY aileron function? Or does flipping the flap switch immobilize both ailerons in the down position?

And, lastly, the GeeBee-Z is a sport plane....a pylon racer I believe. I was thinking that having flap function would allow me to land it more slowly as well as fly it at slower speeds if I wanted. Is this correct thinking? Or are there other considerations that must be made?
