The XFV-12, which could not demonstrate vertical flight, was far from meeting expectations, and the project was canceled before the second XFV-12 was completed. [3] Various models for wind tunnel tests were built for the Convair Model 200, as well as a model for researching the air currents during vertical takeoff and landing.
