I have flown the DX7 now since it first came out. I fly anything from micro indoors to 46% with it, including heli's. Never had an issue. The best part is what some of these guys are talking about, the receivers. Spektrum and JR make a receiver for anything, and they are reasonable in price. I use to be a Futaba guy all the way but once I switched to Spektrum/JR there will be no going back. The 2 transmitters deffinately feel different, it doesn't take long to get use to the opposite one you have been flying though. Definately look at how many receivers you need and what type you are going to need (micro, giant, heli, etc.) There is alot of good stuff out there.
