: "Otto William Timm flew his first aircraft in 1911 and the following year became one of the first pilots involved in barnstorming (initially called 'exhibition' flying). By the time Timm formed the O.W. Timm Aircraft Corporation at Glendale, Californis, USA, he had already built several aircraft, including the pictured aircraft which was built at Grinnell, Iowa, in 1917. The engine was an 100 hp six-cylinder air-cooled radial built by William 'Billy' C. Robinson, also of Grinnell. It had an 8 ft (2.44 m) diameter propeller with 6.5 ft (1.98 m) pitch, and a V-type landing gear with 26x4 in (66x10 cm) wheels. Intended for 'exhibition' flying, the aircraft showed great speed, rapid climb and great maneuverability. On the third trial flight, Timm looped the aircraft five times, and was surprised at the small loops it was possible to make with this aircraft.
