Hello Cruzomatic. Yeah I figured that but I have read something about a servo going one way the other going the other when it comes to flaps, ailerons or something I just can't remember... I was just seeing if this is what happens with Y extensions or not. I have a Futaba 72mhz right now but am deciding between the 7channel Futaba FASST or the 7 Channel Spektrum. I have no problems with reversing servos I think I had to do that to all mine in my current plane.
