We will never know, since X planes are top secret projects. Sure 1 or 2 might leak out into the public.

lol that x-50 is something else. i wonder what it could be practically used for???
he RSRA was a unique pure research aircraft developed to fill the void between design analysis, wind tunnel testing, and flight results of rotor aircraft. The joint NASA/Army project began in December of 1970, with the first of two aircraft arriving from Sikorsky on February 11, 1979. The aircraft was designed to investigate the concepts involved with stopping the main rotor in flight, with the large blades then providing aerodynamic lift assistance to the stubby conventional wings extending from the
A Rotor Systems Research Aircraft (RSRA) underwent limited ground and flight tests at the Dryden Flight Research Center, Edwards, California, in spring of 1984. The purpose of the tests were to train pilots and to verify and develop the design flight envelope established by the Sikorsky Aircraft Company.

Waynos - I see why you think that, but there VERY different.
The Boeing X-50 is trying to do something revolutionary, while the X-Wing had normal wings and normal jet engines.
Yes, but aren't you describing flight method the S-72 derived demonstrator, whos real function was the basic first step of proving that the idea of stopping the rotor in flight was sound
what we see in the X-50 is where the X-wing designers realised they were going wrong
