I agree with Stang.

Anyone looking to begin in this hobby should begin on a 2.4 GHZ system. There are 2 currently available, one (DX-7) is in general use. There is one from Futaba now, and there is a system on the horizon which will allow us to convert our old transmitters to 2.4 GHZ.

I don't think anyone should be starting this hobby on 72MHZ these days. 2.4 will allow more growth in the future.

(DX-7 is made by JR for Horizon)
