So I think one of the biggest challenges in getting into a Tiny Trak is cost and complexity. I previously used N20 gearmotors, but the cost of them plus an ESC is a little overwhelming. Not to mention, having to buy hardware / screw kit to assemble. I'm working on a TinyTrak design which will be 100% 3D printable including TPU tracks, without use of screws or tools for assembly. All axles clip into the frame, and all frame parts are designed to snap together.
