Re: pic: Tube-Based Hex Chassis
Flipping the outer wheels to the inside of the chassis has been suggested but it does make your footprint nice. You also might as well make the center wheel super wide (3"?) to take advantage of the neat effect roughtop tread has on traction when you have a small, wide wheel.
As for your belly pan, I would leave a bit of a web / perimeter around the inside of the chassis instead of starting the lightening pattern immediately after the tube "ends". Maybe it's just aesthetics, but I think it's a smidge stronger that way. I would also use more smaller cutouts rather than the big wide cutouts so that the belly pan is a fair bit stiffer.
You can probably get away with 16 wall tubing for all of the bumper supports, which is a lot stronger than lightened 1/8" wall tubing and lighter than most lightening patterns in 1/8".
