Description

This version is outdated and has a number of problems. I do not recommend assembling it — only for reference. A second version is currently being actively prepared and tested, which has a lower center of gravity, proper suspension, and tuning capabilities. The list of hardware and the overall architecture remain the same, but there are very many small changes.
