I agree with RCKen in that I feel you should learn to fly without any "help" from your transmitter. There's no need for dual rates, exponential, programmed maneuvers, etc. on a trainer. And if you use these features when you learn, they will be a crutch later on that will impede your progress.

That being said, if you are serious about the hobby, get as much radio as you can afford. The 9CAPS should last you for many years to come. I've been happy with mine so far.
