Buy X-Aero Aircraft
In addition to developing high-fidelity flight models to enhance other developer's aircraft, X-Aerodynamics has some stand-alone aircraft available.
As you might expect, for these models the flight model is the absolute top priority!
There are no 3D cockpits or high-poly overlays here, just the best flight models I can develop, dressed up with nice textures and a 2D cockpit. They run great on any computer that can run X-plane.
