FSX – Republic XF-91B Thunderceptor V. 1.0. This aircraft was developed in 1949, a US Air Force prototype jet fighter. The feature of the XF-91 Thunderceptor is to have an inverse tapered wing that increases in thickness as it goes outward. And the combination of the jet engine and the rocket engine exceeded the speed of sound for the first time as a fighter aircraft. This package is type B of XF-91 which added a large radome nose. This is a native FSX acceleration project. I enclosed a large drop tank model and a clean model. VC has animation aircraft control.
