I crashed mine a few times as well, but I haven't spent more than 80 bucks in parts yet. 2 days ago I had it upside down at the front of the house, then I had a brain fart and tried to pull up moving the throttle forward......[:@] Broke the boom. again for about the 5th time. So I went and got a tonn of parts, main shaft, head boom, blades etc.... I just tried it with a 2200MAH li-po. WHOA... I thought it would be a bit heavy, but it's just fine. Head speed is now seriously up, I'll have to put in the motor from the aerobatic kit, cause I think I'm soon gonna fry the stock motor, but talk about being stable.... With the high head speed, it hovers stable now.
The only problem is the size of the battery, I can't put the canopy on......
