I'm very happy with my E-flite Blade. I have "broken" it. Two moderate crashes have cost me a set of bearings and a gear for the tail rotor. So far it has only broken where it was intended to break. If I beefed those parts up, I'm sure I'd be replacing a motor or the 4 in 1. The biggest piece of advice is to take it slow. Only go as far as you comfortably can while still in control. Once there, push just a tiny bit further and then come back. Stay in control of the machine.
