Curtiss XP-10

On 18 June 1928, the USAAC placed a contract with Curtiss for one prototype of the XP-10 single-seat fighter powered by a 600hp V-1570-17 Conqueror engine. Of mixed construction with fabric-covered steel-tube fuselage and plywood-covered wooden wings, the XP-10 placed emphasis on aerodynamic cleanliness and utilised surface evaporation wing radiators and a gulled upper wing. Delivered in August 1928, the XP-10 was tested until October 1930, but continuous problems with the cooling system prevented further development.
