I'd second what Campgems said. When I started out, I flew my H9 Alpha 40 on the same JR S400 TX as my Four Star. I just built the Four Star so that all of the servo directions were the same as the Alpha, and then I mechanically adjusted the trims to be as close as possible. It still required a bit of re-trimming between planes, but it worked OK.

By my third plane, I finally broke down and got a computer radio with model memory. It is definitely a lot easier.

Good luck
