RE: 4 aileron servos - need TX help
Jerry,
You can plug the lower wing ailerons in to channel 2 (or the dedicated aieleron channel). Then plug the second set of ailerons into channel 6. Go into the program and disenable that switch so there is no chance of cutting it off. Then go to the mixing menu and mix channel 6 (SLV) to the aileron channel (MSTR). You can then make that mix 100% or whichever you need and reverse it if need be. Not hard to do if I have my radio sitting in front of me. You can do it without three Y's for sure. The 9303 is a pretty versatile radio.
Good luck
Tommy
