Abstract
A control device comprising: a reference frame; a stick; a pivot mounting the stick to the reference frame and defining a pivot axis; and an actuator for rotating the stick about the pivot axis. Mass balance is achieved by offsetting the centers of mass of the actuator and the stick from the pivot axis. Typically a line joining the centers of mass of the actuator and the stick substantially passes through the pivot axis. The actuator is a rotary actuator having a stator coupled to the stick and a rotor coupled to the reference frame.
