There is provided a counter-torque control assembly for mounting to a tail boom of a rotorcraft where the rotorcraft has a single main rotor, no tail rotor, and no tail fin. The assembly has an air intake chamber with at least a first opening for receiving an air flow stream and a vane assembly housed within the air intake chamber. The vane assembly has at least two vane elements capable of counter-rotation in the air flow stream. The assembly further has one or more microjet propulsion devices coupled to a second end of the air intake chamber. The one or more microjet propulsion devices draw the air flow stream over the vane elements to generate a counter-torque force to counter a torque from the single main rotor.
