Summary

MRC24 is a micro RC Rock Crawler in approx. 1/24 scale using small hub motors to directly drive all wheels. It's a fun toy to climb slowly rocks and terrain.

All main parts are 3d printed: chassis, front and rear axle. However, you will need additional electronics and hardware to complete the crawler. Basic 3d printing and RC knowledge is recommended before starting this build. Feel free to mod parts and share them by using the hashtag #mrc24.
