as an experimental long-range monoplane. The aircraft was a high-wing cantilever monoplane with unswept wings of wooden structure with a fabric covering. It had a box section wooden fuselage with a single Vertical stabilizer, fin. The crew of two sat in an open cockpit ahead of the wing. Two aircraft were built between 1920 and 1921 at Stag Lane Aerodrome. Early testing of the first aircraft (Serial number, Serial ''J6849'') resulted in a redesign of the Piston engine, engine installation. The second aircraft (Registered G-EAYO) was built as a ten-seat commercial aircraft. The airlines were not interested and further development was abandoned, effort being put into the biplane de Havilland DH.34. A proposed military reconnaissance version, the DH.30, was never built. The two aircraft finished their life at RAF Martlesham Heath with tests and trials, particularly on the thick-section cantilever wings. The Doncaster was the first British aircraft to use such wings.
