Autorotate like a UH1 missing a tail rotor: keep the forward airspeed up above some number. In the UH1 it was 80 mph. You really don't need rudder to prevent torque turns autorotating, but it is used for direction control.
AFAIK, the NOTAR only lost rudder control if the turbine stopped solid. If it was still spinning you had some airflow
Pitcairn autogyros only had enough rudder to stop puller engine torque
