bugdevheli,
your interesting thread provokes the following totally 'outside of the box' idea;
```````````` From the Department of Demented Designs
``` 
````` Where the lights are never turned off; 'cause the light never really came on.
Basically it's a light single seat helicopter, which is connected via a 200 foot cable to an underground generator.
An electric motor in the helicopter drives an extremely high-speed coaxial counterrotating 'rotational energy storage device' [RESD]. The energy is then transferred from the RESD to the rotor-shaft via a constant velocity joint [CVJ].
The RESD is incapable of pitching or rolling because of its very high opposed rotational energy, but the craft can pitch and roll, because of the CVJ.
A device similar to a '
hub spring' is located between the craft and the gimballed RESD. This device will resist any extreme pitch or roll of the craft.
The solo student can do anything his heart desires. But, should he move more than 200 feet from the underground generator, which will 'unplug' the cable, or should he put the craft into an extreme attitude; three things will immediately happen. One, the force of hub spring will dramatically increase. This will align the craft with the RESD and removing all of its pitch and roll. Two, the collective will go to a 'slow descent' rate (not that of autorotation). Last but not least, the pilot's cyclic and collective sticks will become inoperative.
Theoretically, it should be a totally safe way of learning to fly without even the need for an instructor. Simply trial and
error.
