Finally i got it done. After learning a bit about scripting, trying some different scripts out i ended up with this, a stable jet engine with a hell of an "torque", u can go up a straight wall with it ...
The truck has real weights ~ 2 tons and is powered by a spawnengine that shoots balls out which creates movement..
(This engine can pull 10 tons with no problems
)
This engine u can use for Flying if u feel like (i've tried and succeeded)
The only thing that makes this engine fail is that if u roll backwards and "pull" the throttle the balls that spawns fly at the different direction doing nothing, so stop before u try to go forward.
I Copyright this right here right now, if you want to use this engine in an project that u later on POST credits must be given and permission must be granted.
Controls are in game.
Have fun
/Cps
Ps. IF u have a bad computer, To avoid lagg, dont hold the throttle too long, do bursts
