Collective mounted Hook release
Sorry but no pix.
It's exactly the same as the popout release.
But be careful. I was supervising a new 133 operator and he pulled the hook release with the load "SPLAT" at about 100ft.
I always pulled the circuit breaker until I was actually pulling torque.
But definitely beats the collective mounted "bicycle brake" model. What a joke. I know of some crashes because it takes 2 hands to pull the thing.
