I too just took the plunge. 450S CF and got a helluva deal from readyheli.com. Got it in the mail Monday...it's all I've been doing all week
. Stepped up from an AXE CP cause I was just plain tired of that damn little demon doin whatever the hell it wanted. Good for learning to hover though with such a touchy thing. Man, with the Rex, it's all just so smooooooth! Amazing! Even the wife was in awe! I too have the 6EX SS. Great little radio IMO, very locked in feel.
