If you can't find a set with mixes and other sailplane functions in your mode then you may need to look at getting some internal changes made to the transmitter to move the stick functions around.

Frankly I'd suggest you learn to convert over to one of the more standard mode setups. It's one thing to move the throttle ratchet over to the other side but often the channels assigned to the sticks are set and the preprogrammed mixes expect the stick axis' to be where they are supposed to be. In the old days most of the transmitters used sticks which were separate from the circuit boards and were wired. In such setups it was simple to move the wires around to put any channel on any stick and axis. IF you can find a transmitter that still uses this method instead of the ones I've seen where the sticks are soldered right to the boards you could do the same thing. But you will likely find that you are restricting yourself a lot as the need for new or more radio sets comes up. It is likely easier to re-train yourself now before it becomes too ingrained.
