I think the 3gr is 2.4 ghz only. I have one, and it works flawlesly, but lacks ergonomic adaptability. No spring tension adjustment, no angle adjustment for the sticks...awkward menu operation... It's been around for a while.
Receivers are pricey, and given the 4grs is out now i think it makes no sense to get a 3gr unless you're already invested in the 603 fasst receivers. If you wanna go futaba 2.4 ghz sticks, get a 4grs instead of a 3gr.
Cheers
Chris
