I just built the FT Mighty Mini F-22 tonight, and I have encountered a problem with the elevons and my DX4e transmitter. When I flip the mix switch the elevons work, but the stick's controls are swapped. What I mean by this is that (in Mode 2) moving the right stick up/down controls the roll, while moving the right stick to the left/right controls the pitch. I've tried plugging the servos into every channel on my receiver, I've tried using a y-harness, and I've tried every other switch on the transmitter to no avail. Is this possible to fix with the DX4e or do I need a more advanced transmitter? I really can't justify shelling out the money for a better transmitter right now when the DX4e works great for all my other planes.
