Great job on the Minecraft MOB race. My kids have watched it each night before bed since it came out. Thanks for all the great races. You've really made some great videos.
We've made our own open track and are having a great time. The 180 turn works great. I made a little jump at the end so we can have big air bonuses. I'll post some mods soon on thingiverse. I couldn't get the magnets to work very well but painters tape has been an easy fix.
