A joystick control system includes a first pair and a second pair of fluid enclosed resilient tubes with each pair of tubes having generally parallel spaced pressure sensing portions confined within a support housing with one pair of sensing portions disposed perpendicular to the other pair of sensing portions. A control stick extends between the spaced sensing portions of both pairs of tubes and is supported for slight lateral or universal tilting movement. Each pair of tubes is connected to a corresponding sensing transducer which varies electrical output signals according to the pressure applied to the sensing portions of the tubes by the control stick.
