Nice, it's a cool winter project trying to get the weight down and centered as much as possible.

At the start of this year i had my car down to 1595 but i wasn't able to get it up to the mandatory 1700 so i had to loose some titanium and put a normal size steering servo in the car.

For this winter my goal is to reach the 1550 mark.
But still have a reliable car, because this year i had aluminum driveshafts in the rear who of one snapped when i was leading a race.

To get it back up to 1700 i am designing a huge brass weight which will incorporate the battery tray, the little battery tray mounts and the 30 gram weight behind the tank, all made out of one piece of brass.
