using channel 1 and 5 in the radio for my aileron servos and if i remember right it has to be in glid/acro setting . then you just set up flaps on the radio. I would have to do it again to remember exactly on the programming. there is rferences in the manual under GLIDER settings.. for some reason on mine that is the only way channel 1 and 5 will run ailerons without a Y. EX. (ch1 left aleron servo CH5 right aileron servo)
