Re: A very little something different.
Dave, I posted too quickly and left out one important observation. The lifting response of the motor only works when the rotor system is accelerated. If you're at a steady rpm then you will have a large lift force on the blade side, and no upwards force on the motor side. Small restoring forces will be created with the dynamics of the system, but I doubt if the magnitude will be sufficient to allow a level disk equilibrium, or even a convergent oscillation.
It might be worth creating equations of motion for this and then running simulations before going any further.
Matthew.
