Pretty sure I watched an RC Driver video on their build for this - looks like a lot of fun. Please post a build thread!
My shop has a Grasshopper kit for sale - makes me wonder what I'd have to do to it to get it to handle correctly on carpet. Mind you, not to perform or to be competitive - but what changes I'd have to make to the setup to optimize for high-grip, to make it drive consistently and predictably. I feel like it would be a lot of fun to go through that process.
