When the Fokker Universal (known within Fokker as the Model 4) was first developed in 1925, it had a 149 kW (200 hp) Wright J-4 or a 164 kW (220 hp) J-5 engine. The later Standard Universal version was powered by a 246 kW (330 hp) Wright J-6-9 engine. Two gasoline tanks were mounted in the wings near the forward edge. As typical of the era, the pilot sat in an open cockpit forward of the wing’s leading edge. The enclosed cabin below and to the rear of the pilot held four to six passengers or could be fitted for cargo hauling. Cargo capacity was estimated to be approximately 427 kg (940 lb); fuel capacity was 280 l (78 US gal) or 213 kg (468 lb)
