These are all good computer radios:

Futaba:
6EXA
7C (7 CAP for airplanes, 7 CHP for helis and airplanes, 7 CAF etc...)
9C (expen$ive)

JR:
6102
8103
9303 (also expen$ive)

The good thing about JR radios is that the model number tells you the radio's specs. For example, the 6102 has 6 channels, 10 model memory, 2 program mixes (airplane, heli)

I'm surprised that this hasn't turned into a JR versus Futaba thread.

Hope this helps
