DW Image # 84: De Havilland DH-4 rear cockpit control stick assembly, circa 1918

De Havilland DH-4 rear cockpit control stick at the Dayton-Wright Airplane Company. The De Havilland DH-4 rear cockpit control stick is the subject of the photograph at a Dayton-Wright Airplane Company factory, circa 1918. When the stick moves forward and backward it pivots the horizontal bar. The elevators are connected to the bar by cables that run to the arms at the ends of the bar. If the stick moves side to side pivoting on the assembly attached to the bar it twists the bar connected to it. This bar is attached to a swivel bracket on the front stick and moves the front stick in the same direction. The front stick is connected to the ailerons and the elevators through the rear stick.
