| Steve,
I was running a 1090kv MT Dragon (Axi clone) motor with an 18 tooth pinion and a 4 cell 3700 Flitepower battery. Around 2800 rpm.
As you can see, the flybar is bent in a U shape and the head block snapped off. The broken blade was found about 200 feet from the heli. Also notice there are no signs of a boom strike either on the boom or the blades. The blade failed, causing an imbalance that snapped the head block and bent the flybar that way.
