RE: Gaui 550 problems!...HELLLLP!
I used the 60 or 75 I'm not sure which and I dont have the Heli with me right now. I think it was the 75 but I'm not sure.
As far as the other ones you posted go I have not tried them. I wouldnt go with some fly by night brand unless I knew someone how used it, the esc goes and you will get a crash course in auto's[X(]</p>
