Built to Rock: A Custom, Small-Scale R/C Crawler Course! [Pics]

One of the many reasons I’m drawn to small-scale R/C vehicles is their take anywhere, do “just about anything” versatility. If the weather isn’t cooperating, you can always set up an indoor race course or obstacles to crawl over. Even better, is when you can set up an outdoor challenge, testing both your own driving ability, as well as your creativity.

Fellow small-scale fan, Seth, has shared some photos of his custom-built outdoor crawling course for his 1/18-scale Losi crawler and 1/24-scale Redcat Racing Sumo. Combining natural and handmade elements, he’s created a challenging outdoor escape for his R/C enjoyment. Seth calls it “a work in progress” and has been in development for over 5 months, with the size spanning 30 feet wide and 60 feet long.

From the course layout to the modified crawling rigs, I’d say Seth has done an amazing job making his hobby his own. If you have a custom small-scale vehicle or driving space, be sure to share it with me on Twitter and Facebook.
