Thanks !

Things have stalled quite a bit since I've been having issues with ship hovering not being strong enough ... However I think I'm holding the right end as I'm getting pretty convincing results such as in the original game : https://www.youtube.com/watch?v=yTJvU4jofmU

Sampa Run track in fact is the most problematic as when going too fast the ship would either hit the floor or the ceiling, currently it's mostly behaving like in the original game but still needs tweaking. So hopefully I will soon be done with that and post a much more realistic update (and finally continue in implementing the rest of the game)
