as of the last team update I believe that our chassis will be legal, just in case we will have some new plates milled from a metric sheet we have, that is like just a little more then 1/8th. because it will be the same as 1/8, but its not.
also now that we have both of our twins driving it is really interesting how well they drive with trailers, our tank drive is long but the front wheals do not stick out as far as the back, which really improves our turning. we were drifting and everything. I am not sure why but it drives much better then the 2007 robot on regolith. but I think it has to do with the differnce in axle lenghtes from front to back
