The Redfern DH-2 is an American homebuilt aircraft that was designed by Walter Redfern and produced by the Walter Redfern Company of Post Falls, Idaho, based upon the 1915 Airco DH.2 fighter aircraft. When it was available the aircraft was supplied in the form of plans for amateur construction.

Design and development
The DH-2 features a biplane layout, a single-seat open cockpit, fixed conventional landing gear with and a single engine in pusher configuration.

The tail is an open lattice structure to fit around the rearwards-facing propeller and is also cable-braced. The acceptable power range is 125 to 150 hp and the standard engine used is the 125 hp Kinner B-5 five cylinder radial engine.

The DH-2 has a typical empty weight of 1100 lb and a gross weight of 1450 lb, giving a useful load of 350 lb. With full fuel of 30 u.s.gal the payload for the pilot and baggage is 170 lb.

The standard day, sea level, no wind, take off with a 125 hp engine is 100 ft and the landing roll is 300 ft.

The manufacturer estimated the construction time from the supplied plans as 2500 hours.
