CONTEST: RACE My third entry

Everyone making contests. I thought, I can do it too.
******************************************************

In this contest you should make a car, that should be faster than others.
At the end of the contest (1st November), I will put your cars in one level.

Rules:
No lua.
No gravity management.
No no fans.
No motors (except linear).
No Leo's overpower bug.
Must not be longer than two platforms at the start.
You should build only on them.
Should be a derivative of this level.
Derivatives must be allowed.
No transmitters (I will use multi-select).

That's it. GOOD LUCK.
