As for the programming, it's pretty much exactly the same. The main difference is you can run high voltage through the 7300 where as you can't with the 7200. If you are running the 7200 now, and have no plans on running over 8.5 volts to your servos (the 7300 can handle 9.6 volts), then just stick with the 7200. No sense in spending more money on the same flying style, which is awesome! lol.
