Abstract: The stick of a joystick type control device is rigidly affixed to a carrier plate that extends normal to it. The plate is gimbal mounted on a fixed base and has four reaction receiving elements equidistant from the stick axis, arranged two along each gimbal axis, at opposite sides of the stick. Four springs react, all in the same direction, between the fixed base and the plate, one against each reaction receiving element. When the stick is in a normal position the springs exert equal forces.
