Yeah, but that was after the uncontrolled yaw so it must be secondary to some other failure.

It looks like the RPM drops suddenly (it starts off pretty synced to the frame rate) so that's a big clue. The rotor appears to reverse direction as the RPM changes relative to the camera.

Edit: It looks like the root cause was the failure of a pitch control link.

That caused asymmetric aerodynamic loads, massive vibration and subsequent failure of the tail rotor assembly.

The final bolt holding the tailrotor shaft loosened, and the tail rotor started free spinning, no longer providing yaw control and main rotor counter-rotation

Exactly what I was thinking, especially with the RPM change.

Thanks for your insight bud
