He indeed probably wants a 2.4ghz radio.....there kinda the new craze as far as transmitters go. And well worth the money too. I personally recommend Futaba. We would need to know a tiny bit more about this guy as far as what he flies. If he's flying basic radio controlled planes like most of us and not going extremely overboard like some guys,he's probably in need of just a 6 channel radio2.4ghz(not channel as in 37,or 43,or 51 etc.,2.4's dont use them)......he probably wants this for $220:

Same radio,but comes WITH extra stuff he'll be able to use for $40 more:

I could be wrong,but 9 chances out of 10,this is whats he wants
