I am building a versa wing, and this is the first time I have used the elevon mix with my Futaba T6EX radio. I read the manual and set it up as it says. The elevator throws are correct, however the aileron throws are opposite. I reversed the aileron servos and now the ailerons work like the elevator and vise versa. I also tried switching the servos to the opposite channel in the receiver, but had the same result in the opposite directions. Can someone help?
