The Whitehead-Beach aeroplane of 1908, constructed at Tunxis Hill, had flatplate-section biplane main wings supplemented by batlike monoplane wings at mid-fuselage. White Japanese silk was used in the wings. A lever controlled the rudder and elevated the batlike wings.
Another incarnation of the Whitehead-Beach biplane, built for Stanley Yale Beach, son of the editor of Scientific American, with shallow camber on the wings and without the supplementary mid-fuselage wings. Note the belt drive from the lower chassis-mounted engine to the twin propellers.
