Scarpar sent us some photos from testing in the Czech Republic and Australia. They're testing both ends of the specture: snow and sand and the performance is good. The optimal surface is probably a dirt track where there’s a little give but reasonably firm. Grass testing including very soft underneath (muddy) was very successful. The new setup with motors inside tracks is a huge step forward in terms of simplicity and ultimately reliability. The goal is for for production prototypes to be produced in March or April, shipping to consumers will be Q2. Stay tune for further updates as they happen!
