When teaching in the Huey....one exercise I liked to do was to put the Governor in Manual....and have the Pilot fly a full circuit using the Throttle to control the Nr....then on the second circuit apply a bit of Left Pedal and have the Pilot remove feet from pedals and use the throttle to control yaw as we flew the full length of the runway at a slow airspeed and about 2-3 feet off the runway. Usually, by the time we got to the end....the Monkey Skill was in place. On the next circuit....quite a bit of left pedal was applied and we did the same drill but slowed the aircraft to the slowest speed the nose would stay centered.....until we determined the slowest speed we could use even if it was a steady hover. The final trip round the pattern was to set up for the same scenario....but this time I asked the Pilot to let the nose go all the way across.....accelerate till the nose swung back over....and repeated that drill as many times as possible before reaching the end of the runway.
That demonstrated to the Pilot the kind of control you might have in a real failure.
Demonstrations are not the real thing.....just as Simulators are good but not the real thing. What you are teaching is the Concepts so the Pilot is better equipped to deal with a real situation.
