Correct me if I'm wrong - still only inexperienced PPL (PF1 - I believe this still entitles me to post, even thouh I do not earn yet as a pilot, but i think professionalism is a manner in which you act - it is not your paycheque).
But I would have thought that the actions for engine failure would be similar whatever the type - Lower collectinve for safe RRPM, and aft cyclic to induce the airflow through the rotors. If neither are done, the autorotation will not be established. Forward airspeed can be adjusted in the auto - obviously depending on height available.
