What parts were they? If they were CNC they probably wouldnt have broken and other parts would have broken instead. I try to configure my helis so that the cheaper parts will break first versus the more expensive which I replace with CNC. My AXE 400 is great, the gyro is pure and total garbage but other than that it flys great for a fairly new flyer like me. I dont fly low much because I like to have time to react. I flew pretty far away and lost orientation but recovered this last weekend which hammers home the fact that the next heli will almost certainly be a 600 class. J
