Design and development

A direct development of the Model F, the Model H introduced side by side seating for the two pilots, with long-span wings similar to the Model F. A short-span version was also produced as the Model HS, marketed as a "Military Flyer" with the improvement of an enclosed fuselage and dual controls.^[2] Its wings were shorter than the Model H for increased speed.^[3]

The Model H was a two place, side-by-side configuration seating, open cockpit, biplane with twin rudders, powered with a single engine, propelled by two chain driven pusher propellers. The engine was fully enclosed in the nose of the aircraft with a driveshaft running rearward to the propeller drive chains.^[4]

Operational history

Howard Reinhart purchased a Wright Model HS for Pancho Villa, who hired him in support of his insurgent force.^[5] It was one of three aircraft in his small air force.^[6]

In 2003, a Wright propeller matching the Model HS specifications was auctioned for over US$25,000. The construction of the propeller was hand carved wood with a linen covering, metal tips and a custom finish.^[7]
