Last week, LevelUp released its 737NG Series U1 for X-Plane. This new update for their original 737NG release comes with new textures, cabins, and a new audio experience to the 737 simulation.
The developers said, “this is a new generation of freeware 737 Next Generation Aircraft, the ultimate successor to the 737 Ultimate Project. A faithful expansion from the default 737, combined with the power of Zibo systems.”
Included in the package is the entire range of 737NG aircraft; the -600, -700, -800, -900, and the -900ER. Each plane comes with its own unique flight profile for a realistic experience. Inside the cockpit, a new CornUI tablet (a reskin of the Zibo tablet) is also introduced and will be expanded on in the future.
You can get the freeware plane from the Threshold forum or via Orbx for X-Plane 11 and X-Plane 12.
