This portable modular rock course from @mountainblox was on my favorites list from the recent NHRSA show. The pieces are textured like real rock and can be assembled in different ways so you can continually alter your courses. The pieces are also magnetic and you can stick gate markers anywhere on them to challenge yourself on new lines. This setup for small crawlers was impressive and I was told there was more to come! . . . #mountainblox #rccrawler #rccar #rcrockcrawler #rcoffroad #rc4x4 #scal
