Build a Rock Crawler So, we heard you want to go Rock Crawling, and you're looking for a way. Well first what is Rock Crawling anyway?

Rock Crawling: The goal of rock crawling is to overcome the largest, most difficult obstacles using any four wheeled vehicle. These obstacles can be anything from a collection of boulders to steep cliff faces. Vehicles can range from stock trucks right off the assembly line to custom hand made machines made specifically for off road terrain.
So in a Radio Control vehicle you can go box stock to highly modified to get you going. Below you will find some Tamiya items to help you start out with your new adventure.
