I flew my 450 pro FB at the AMA show held in Ontario California few weekends ago and CRASHED up side down.....
Right after I touched the blades being inverted, I managed to hit throttle cut before it hit the ground....
I walked away with a broken set of blades, a bent main shaft, and stripped top and bottom gears on the heli
Cost only $30 to fix having to purchase parts at FULL price!!!
