Thanks for sharing!

Thats a realy good start, cetainly is good to see a logic set up in action. Now you can try out your tracks once you have tweaked the handling. You may want to look at constraints for the ships motion too, stopping any bad crashes!

I bet you loved it when you saw your ship flying around! I zoomed out and saw the track- very Zone like!

One question though, what does the ray sensor and the python script do? I'm guessing it aligns the ship to the surafce normal. If this is the case, there is an option 'rotate from normal' in the physics section that might do something similar.
