Great thought! In my mind there would still be a slight force on the body, but maybe I was just sleepy during my physics classes? I would love it if someone could explain it to me.
@barry99705 Not really, it has a tail rotor to be able to control the direction of the body. Whatever rotational forces that is transferred to the body would only be what is transferred by the friction in the bearings.
One would think that a simple rudder of sorts mounted in the downward air stream from the rotor would be enough to provide directional control for the body.
@LEDfoot I agree with barry99705. The article states that the tail rotor is solely for providing direction control but I imagine that some of the power is used to keep the body from turning, due to the friction between the rotor and the body. A roder would not work for that. Furthermore, a roder requires the whole body to move forward (or backward) in order to turn it, a tail rotor however makes rotation on the spot possible.
In either case, it seems that the force of the rotor can be a lot less when using this technique, as opposed to a rotating engine in the body.

@blinddance That's why it still has a small tail rotor.
@barry99705 that's what I thought. Thank you for clarifying :)
