Chassis thoughts... vertical, or horizontal batts

[Serum]

Well, my previous post still is counting;

If you put more weight to the front, you will be able to turn in the rear of the vehicle in corners. While put more to the rear, understeer becomes a fact.

Best way to decide on what you like; make some easy to adjust battery-trays which you can shift easy. The reason why i made the proto-type of the CD savage i posted you earlier. It's hard to tell what the perfect position is. But overall (from my personal experience) slightly to the front takes care of business pretty well.
