i'm doing 3D with it, i'd say about as much as the stock motor can throw, i can't do inverted flight yet though, only hovering and flips and stationary rolls... i started last july.

i doubt you'll need 3~5 years, i'm wanting a better heli already, but never really make up my mind to part with my money. and don't get the professionally built RTF ones, yes, they may be professionally built and test flown, but you'll eventually have to know how to put it together, (ie. an arguement with mother earth ). and i think it's cheaper to get the kit. and you can put what ever electronic acc.s you like in it.
