So I've gathered that there's some interest in a Top Gear test track for BeamNG, but unfortunately a brief perusal of this subforum indicates that any previous attempts have either been long abandoned, or are somewhat "Russian", or both.
Here's a quick attempt to rectify the problem:
Sunburst Sport RS 1:26.6:
Although this is an accurate, 1:1 scale "reality port", please note that this is not a replica of the whole airfield, merely the parts used for the Top Gear test track. I don't have time to model everything on it, let alone the places you're not supposed to go anyway. Flying planes on this map will probably suck.
As always, any non-stock art assets on this map were created by me and may be used without permission for any purpose.
I'll start a leaderboard for the different vehicles, provided you record your attempts and post them as videos.
Just drop the zip in your My Documents/BeamNG.drive/mods folder.
Texture quality needs to be on "Normal" or "High", otherwise the game will crash during load.
