Many asked for it and after teasing it for the first time in August 2018 here it is almost 4 years later (oops).
The Gulfstream IV is a private jet and larger than all vanilla GTA V private jets, including the Miljet. The aircraft comes with a custom vehiclelayout allowing 8 occupants to properly enter and exit. Additionally, 5 liveries are included (4 civilian, 1 C-37A type livery). All standard GTA features are working, including working cockpit cockpit instruments.
Original model made by ghansen for X-Plane 11
