Kit #AA2004. 1/72 scale. Highly-detailed resin kit with decals. In 1958, Curtiss-Wright started a four-passenger VTOL commercial aircraft program without any government support. It was designed with a tilting propeller at each wing tip, allowing for the nacelle to rotate in vertical-pointing direction for take off & landing and horizontal-pointing direction for cruise. When the two prototypes were almost completed, Curtiss-Wright decided to offer the aircraft to the Air Force for VTOL technologies development of the Tri-Service military needs. Under the Air Force agreement, three prototypes would be built, designated X-19. Two were to be used for flight tests and one for structural testing. The first prototype's first flight was in November 1963. Many problems surfaced during the following months. Two years later it crashed due to parts failures and pilot's error. The Air Force still wanted to test the second prototype. However, Curtiss-Wright saw no future business in civil VTOL transport and ended the program. The first X-19 completed test flight total of 3.85 hours and the second X-19 was never flown.
