HISTORY The Curtiss Model 75 was developed by Donovan A. Berlin, a former Northrop designer, and had more in common with earlier Northrop aircraft than with any previous Curtiss design. It was an all-metal low-wing monoplane, with a fully retractable undercarriage - all three wheels retracted, with the main wheels rotating through ninety degrees on their axis and then folding back into the rear of the wing. The aircraft was powered by a radial engine, starting with an experimental Wright engine.
