A device and method are disclosed for continuous torque/anti-torque force balance, except for trim adjustments. The torque requirements of a single lift rotor are balanced while lifting varying load weights and with varying power settings. A single lift rotor plane of rotation is parallel to and just below the flared air entry end of a relatively short, cylindrical, vertical duct. The lift rotor is closely contained by the duct's inside diameter, and just above a fixed-pitch, essentially vertical, array of air foil shaped vanes. In this configuration, lateral lift in an anti-torque rotational direction is generated, in direct proportion to the lift rotor torque requirements by the forced interaction of the vanes with the swirl air flow component of the lift rotor's rotor wash.
