AnFI,
Correct, the collective has to be lowered very soon after the throttle chop. Throttle chop stops the yaw very quickly, lowering the collective not so quick. This is experienced advanced instructor technique using something with blade inertia better than an R22, so not something you'd expect at a Florida pilot sausage factory.
The point (and my original point) was that the thread was erroneously drifting into stuck pedal or fixed-pitch training techniques. This incident was a loss of tailrotor thrust requiring different training techniques to prepare the pilot. Pretty sad to see that neither fixed-pitch nor loss of tailrotor thrust is widely taught in the rest of the world.
Maybe just a Canadian thing because of all the confined area work here risking a tailrotor strike, or flying external loads with the risk of something coming up and taking the tailrotor out.
Some poster said any tailrotor problem was unlikely in a career. Flying only from the middle of a runway, and no exteral loads, I'd say the risk is much lower but still there as witnessed by the incident in this thread.
