Abstract
A flight control system increases the automatic control authority over, preferably, a helicopter yaw axis. A limited authority series servo is complemented with a full authority parallel servo. The parallel servo is driven by a combination of a trim command signal and a signal representing the excess of the yaw command signal over the amplitude limited drive signal to the series servo.
