Give your Tamiya Mini 4WD THE BIGWIG RS a second life by transforming it from a track-bound model into a fully proportional, radio-controlled 2WD racer. This project merges 3D-printed precision with standard micro RC electronics to create a nimble, agile machine. The assembly is straightforward, as the printed parts are designed to be easily screwed together. Depending on your components, some soldering may be required for the ESC or battery connections.
