I didn't read all the inputs on this subject. But surely someone looking after their aircraft would understand that the poor old tail rotor is not designed for that sort of treatment.
It's all very well to get away with it in a Hughes 500 or R-22 on occasions, but put yourself in a S-61 or CH-53 where you still apply the same theories of flight to the tail rotor. You can do that manoeuvre in these aircraft, but you had better let the next pilot or engineer know that you may have stressed the aircraft.
No pilot worth his salt is going to kick the arse out of a helicopter to get the job done, as there is a fine line to that envelope where you're a professional or one of those other guys.
But: That manoeuvre you mentioned, if you're in the **** , of course it'll get you out of it.
MERRY CHRISTMAS!!
