Yes Crab, but do you have a better idea for training? At least with the repetition of autos you get to a point, where if the nose yaws suddenly, you just lower the collective and that buys you time. And let me add this, the clues in training are also wrong. I can feel the throttle turning when the instructor chops it. I can even feel it, when he/she touches it. Or see it in my peripheral vision (a clue is when he leans forward to cover his hand). Here a simulator is better, but in the sim, everybody knows also that everything will go wrong.
I do tool around on my own, I am an instructor after all, but not with pax, that's for sure.
