When choosing your radio, you might want to consider the Futaba 7C. The FM version w/o digital servos (which you don't need right now) is $239 and the FM version w/ digital servos is only $10 more. Also, if you run a forum search on Tower Hobbies discount codes (the codes you enter when you checkout that take money off the total), you will find one for I believe $40 off $249.99 or $30 off $200 or more. That now brings the price down to the levels of the 6EXA almost. Believe me, you will not regret buying a radio you can grow into. I myself have the 6EXA and now I have a helicopter (Kyosho Caliber 5) that I can't fly yet b/c the 6EXA has no heli programming and no way to get it either. I regret buying the 6EXA. I should have ponied up the extra for the 7C to begin with. I would tend to believe that you won't need more radio than the 7C for a few years at least if ever.
JMO though.
Here's the link to the 7CAF at Tower
