Though the dx4 that comes with the super cub, and the dx5 that comes with the apprentice can be used for other models, they have no model memory- so you would have to rebind, reverse channels as needed and retrim every time you switch planes.

That's why if I had it to do over again, I'd buy a computer transmitter right off the bat, and get a reciever ready or plug and play plane, like the plug and play version of the Apprentice. You would also need batteries and a charger, but like the transmitter that comes with the ready to fly version, if you get into the hobby you would soon be wanting a better charger than what typically comes with planes.

For me, I went with the ready to fly apprentice, and soon purchased a radian pro. After one day at the field flying both off the dx5, I ran out and got a dx8. Having 3 levels of dual rates and expo is really nice.

Dx5 is now used for a skydiver, so it wasn't a total waste...
