Can you run an AC rotor on an small inverter?  Maybe a true sine inverter. 
Or would the inverter be too electrically noisy?
I also wonder if a brushed DC motor would be noisy too. Right up there with the antennas.
Maybe they use a brushless or stepper motor. ???

The price for the basic system prior to its discontinuation was $799, although I don’t know an apples to apples comparison based on what is included with this package.
