RVDT: None of the dozen or so HEUT courses I've done have taught the pilot to purposely roll the cab over...where do you do your training?
The ones I used taught: ditch / flot bags (if fitted) / shut rotors down / jettison doors / disorientation arms / egress.
["Walking all over you" suggests you are used to a troop carrier/lots of pax. I am talking about GA light helo and or 2+ pax.
