how do I set it up so when I input elevator, the ailerons act as flaps in a mix? I want a few degrees of flaps (ailerons both acting as flaps) when I input up or down elevator. I have tried to put 1 aileron in channel 6 and that didn't work. suprisingly enough, the one in channel 1 only worked one way like a flap. is there multiple mixes I need to activate?
