Been having issues with this mod not working properly and cannot find any information on the mod itself aside from this one forum post.
For starters, it doesn't seem to matter what wheels I put on the bodies. They don't seem to touch the ground. They spin freely and the vehicle refuses to move.
The one time I did manage to get the vehicle to move, it only turns to the right and has little to no power to move forward. I couldn't even climb the tiny incline from the grass back up onto the runway.
I didn't put anything else on the vehicle. It was just the body and the 4 wheels.
