Well, looking at the rx, it doesn't seem easily possible to reverse the servos from the rx anyway...I'd have to yank the stick bases out and rewire..a bit messy. The non working servo is on the right when facing from the back to front of heli...and it's the up/down on the stick (right side of tx) that's not working...side to side is the other servo and it works fine..and the acceleration stick on left works fine too.
