ABSTRACT:
A helicopter control system for controlling cyclic pitch, collective pitch, throttle and rudder. A handle is secured to a vertical shaft slidable or telescopic within a cylindrical tube. A locking device permits the tube and shaft to be moved as a unit to control cyclic pitch. Vertical movement of the shaft controls collective pitch. Rotation of the shaft controls the tail rotor. A twist-grip on the handle is provided for throttle control. The handle may be adjusted through a ball joint for pilot comfort.
