This invention is a servo mounting system, which allows a servo with a
rotating output shaft to directly power an aircraft control surface. A
specially designed servo mount securely positions the servo with the
central axis of its rotational output shaft on, and axially aligned with,
the hinge line of the control surface it drives. The servo shaft and
servo body are directly connected to the airframe and control surface,
thereby conserving rotational motion while driving control movement.
Electronic means are then used to control the neutral point and the limit
of travel of the servo. The system eliminates lost motion without
generating adverse linear loads within the drive assembly.
