So it would no be enough to have a small counter-rotating rotor: the helicopter would still spin as it dumped angular momentum into the air. | |

It's probably cheaper to have the standard arrangement of one main propeller and some method to counteract the torque. The Wikipedia artcile on helicopters goes into some detail. | |
