I think folks should consider the Century Swift rather than the Trex 600(please don't kill me, I have an SE and love it more than life itself). The parts for the Swift are cheaper than the parts for the 450 series of Trex helis![X(] I know that some people will say that Align is a proven company, and they are. But Century Helicopters has been around far longer than Align. As far as electronics, the Swift would use the same as th Trex 600. Also, I would agree with the equipment ultraviolet says for either of the helis.
