The Aero Design DG-1 (registered N10E) is an American racing aircraft designed by David Garber in an attempt to break the world airspeed record for a piston-engined aircraft. It is a single-seat aircraft with two Mazda RX-3 engines installed, one driving a tractor propeller, the other driving a pusher. The fuselage is bullet-shaped and highly streamlined and features a mid-wing and cruciform tail. It first flew on 25 July 1977.
After being displayed at the Sun 'n Fun air museum at Lakeland, Florida for some years, the aircraft was being offered for sale in 2005 with an asking price of $125,000 (USD).
