Has anyone changed the Top Gun Tx and Rx for a Spektrum 6xi Tx and Rx? If so, grateful if you could let me know which servos you plugged into which Rx ports and what settings you used in your TX for Swash Mix and for reversed functions. I can get all functions:- aileron, elevator and rudder working in the correct direction but cannot get all three swash servos to move up or down together?? Any suggestions, hints etc. gratefully received.
