I own the futaba 9 c radio and in order to set up my ailerons I have one on channel 1 and the other on channel 7. I had to activate the ail dif in the radio to get them both to work. when I try to set up faperons I get error message: wing mixing on. In order to get rid of the error I have to deactivate the ail dif. Then only one aileron works. Im soooooooooooo confused. How do I get both the ailerons and flaperons to work properly. Eternally grateful, Superfli
