My money would be on Vario (biased huh?)

Seriously though strart off with a good 50 size heli like the Raptor 50, Century Raven 50, Hirobo Sceadu 50 or something along those lines. Get your flying skill down pat and then consider putting that 50 ship in a fuse. After getting a scaler under your belt move on to something bigger, take your time.
