That gives you 35 lbs in the lightest config, and 45 lbs in the heaviest config.
EDIT: Maybe 15 lbs for the metal is too much. The other parts are still correct, but they weight of the metal depends on if you use sheet or box, and if you count supports for bumpers and other structures in that weight. That 15 lbs is about what ours weighs with a box WCD design, and all bumper mounting included.

Yes, that was including 6 CIM motors. It was designed with rectangular aluminum tubing (we can't do sheet metal yet) and Colson wheels. After entering in all the weights in Inventor I'm getting 41 lbs.

Absolutely. I'm not designing for weight, but I want to make sure I don't spec something that chews up too much of our gaming mechanism budget.
