The DG-1 holds the distinction of being the first custom-built Unlimited Class racer to be built in the United States after the 1930s. It is intended for competition in that category as recognized by the United States Air Racing Association of the National Aeronautic Association. The prototype flew in 1978, and in addition to racing, the design is adaptable for follow-up production of two-place, tandem seating models. It can be modified easily to a remotely piloted vehicle, and design studies examined the use of a J-85 series GE turbojet propulsion unit. The wings are the cantilevered mid-wing type with a fiberglass reinforced plastic spar, and the wings are foam-filled internally. The fuselage is a steel-tube frame covered by plywood and is fiberglass reinforced. Power is supplied by fore and aft Mazda rotary auto engines modified to produce in excess of 330 hp each. Both are fuel injected and turbocharged by custom AiResearch units and turn 68-inch three blade propellers. This kit is no longer available.
