Choose a Large Area for Operating Fast RCs

Very fast electric RCs and nitro RC cars and trucks need more room to operate than slower moving RC vehicles. While you could run around in very fast circles (and thus in a smaller area) most of the time you're going to want to break out of that circle and go all out in a straight line.

Choose an area (such as large parking lot, park, or a designated RC track) that will allow you adequate room to maneuver and react (stop/turn) while traveling at high speeds. And the more vehicles operating in the area the more space you need.
