Design and development
The aircraft features a strut-braced triplane layout, a single-seat open cockpit, fixed conventional landing gear and a single engine in tractor configuration.
The Sands Fokker Dr.1 Triplane is made from welded steel tubing and wood, with its flying surfaces covered in doped aircraft fabric. The cockpit width is 28 in (71 cm). The acceptable power range is 110 to 185 hp (82 to 138 kW) and the standard engines used are the 160 hp (119 kW) Lycoming O-320, the 185 hp (138 kW) Lycoming O-360, the 110 hp (82 kW) Le Rhône 9J rotary engine or the 125 hp (93 kW) Warner Scarab radial engine powerplant. The Le Rhône 9J was the direct basis for the Oberursel Ur.II 110 PS German umlaufmotor rotary that powered production Dr.Is in 1917-18.
The aircraft has a typical empty weight of 1,150 lb (520 kg) and a gross weight of 1,600 lb (730 kg), giving a useful load of 450 lb (200 kg). With full fuel of 23 U.S. gallons (87 L; 19 imp gal) the payload for the pilot and baggage is 312 lb (142 kg).
The standard day, sea level, no wind, take off with a 185 hp (138 kW) engine is 300 ft (91 m) and the landing roll is 200 ft (61 m).
The designer estimated the construction time from the supplied kit as 3,000 hours.
