hi, i have just bought a flying wing to get me into electrics and i am having trouble setting up the eleveon. I have a futaba 6exa, and have switched the w.mix to el like it says in the manual, and have pluged the left elevon in to channel 1 and right into channel 2, my problem is when i press across on the right hand stick (which is normally alerons) both of the servos move in the same direction, like a rudder, i have tried changing the channels on each wing but the servos just go in opposite direction, can someone help me please?
