i use an interface for my G2, Futaba T6XAs, every thing is ok eccept retract can't operate. I have check with the transmitter calibration chanel 5 was functional but the plane landing gear doesn't retract when the switch was hit! Can some one help me on this!

Did you make an edit of the plane you are running? Once in the edited version, go to the screen with the servo set ups and reassign the computer's retract servo to the channel on your transmitter that corresponds to retracts. I have to do this all of the time with my Futaba 6 channel. Seems G2 is predicated on a 7 channel transmitter so you have to do some reassigning......etc.

Yes It Works!!! Thanks a lot!!!
