Now on version beta 1.1, the latest release improves the shape of the nose, improved wings, and various other tweaks that improve the feel and autopilot. You are required to have the beta 1.0 version prior to installing beta 1.1.
While designed for X-Plane 9.70, it will function in X-Plane with a few issues that will be addressed at a later date.
I also added SSG to the X-Plane Directory hosted here at ARoMO.
Update 18mar12 – SSG releases the 747-8 Freighter beta 1.0 at the .org!
