Sheet Metal, 8-Wheel Drive Design

27x33 in long configuration translates to 120 total inches on the frame perimeter. The rules this year limit you to 112 inches on the frame perimeter.

A new chassis, based on this one, is in the works. It complies with this year's dimensions. It is 6WD wide with 4inch Colsons and the VEXPRO 6 Cim gearboxes.

Do you plan on driving that with 6 CIMs? We were looking into using that gearbox with 2 CIMs and something else...maybe a 775 through a planetary, or a BAG motor put through something(VersaPlanetary won't work for this, right? EDIT: Nevermind, I just saw that there is a CIM output kit)

We have decided to go with a 6-wheel design for this years design. We were wondering about how much to drop the center wheel. Since we are designing our robot wide instead of long we're only getting about an 18.5 in wheel base. I know that 6-wheel drives usually drop their center wheels 1/16-1/8 ". Considering our wheel base what would be the best choice?

I'm hoping by "6 wheel drive wide robot with 18.5" wheelbase" you mean the distance between your front and back wheels are 18.5", with the distance between your center wheels and the outer wheels being 9.25". In every scenario I've seen, 1/8" is the perfect amount for a drop on a 6wd.
