Chili Fixins' is coming along nicely. I re-built its armor in Lexan and re-positioned the axles to take a little tension off the drive belts. What's more, the electronics are hooked up and it now runs using "tank steering". I prefex mix steering but that may not be possible since each drive motor has its own ESC. Further research needed.
Still some finish work to do (like, say, taking the wrapping off the Lexan), but I'm pleased with the state of things. Currently just slightly north of 1 pound, so I'll have to trim some weight, too.
