Fling,
I would not simplify the control issue by showing how to not-die by clever application of un-working controls after you drive your aircraft out of control. I would rather teach not driving out of control to begin with. I would teach how to not get zero g.
Also, in the rapid auto entry zero g event, the rotor is driven down (by the pilot's fast collective drop) so that the rotor descends faster than the fuselage, thus unloading the rotorhead.
