The Wittman DFA aka Little Bonzo is a homebuilt racing aircraft designed to compete in midget racing.
Steve Wittman had started air racing in 1926 using various aircraft. In March 1931, he designed his own purpose-built aircraft in Oshkosh, Wisconsin, the Wittman Chief Oshkosh. After World War II, a new class of Midget air racing was formed with Wittmans efforts.[1] Wittman re-engined "Chief Oshkosh" and renamed it "Bonzo". After several successful races in Cleveland in 1948, a cleaner sister ship "Little Bonzo" was built. The name is a reference to Wittman's much larger racer, the Wittman D-12 Bonzo.
The Wittman DFA is a mid-winged conventional geared aircraft built from a welded steel tube fuselage with aircraft fabric covering and wooden wing construction. The DFA differs slightly from Bonzo with a smaller tail surface, a longer tail and a larger canopy. In 1968, the engine was replaced with a Continental O-200 to compete under new race rules.
Steve Wittman and Bill Brennand alternated flying "Buster" and "Little Bonzo". The aircraft was never transported by trailer and was instead always flown to events, where Wittman would perform aerobatics between heats in his racing aircraft.
The Wittman DFA is on display at the EAA Airventure MuseuminOshkosh, Wisconsin.[5]
