Being from the RC Heli world thats a unbalanced blade. Meaning one blade is significantly heavier then the other. We can simulate the same thing to scale by glueing a penny to on blade. In real life something big must knocked that rotor out of balance.Hello,
I found this strange video on youtube:
I wasn't saying stupidity was the cause of that accident, although a better pilot might have sensed the problem developing and reacted in a way to prevent the severe damage.I doubt human stupidity was the cause,
Its called Resonance? I think in the heli world where you get to a certain RPM and if everything not balanced the Resonance tears the heli apart.It would appear that what happened was something caused a "jolt", if you will, on startup that caused motion of the rotor axis beyond what the dampening system could handle, and since it was on the ground, it was allowed to "spiral out of control"; pardon the pun.
I doubt human stupidity was the cause, other than possibly not realizing what was happening and either accelerating or shutting down to cease the resonance.
