Also...while on this subject...I have only four channels on my a/c right now of course being elevator, ailerons, rudder and throttle. I have the 8UAFS 8 channel computer radio...is there any mixing I could or should program in with only the four channels? I suppose I could do some mixing for better turn coordination couldn't I? I don't know how to do all of these mixing functions or even if I should on my trainer.
