Q4. Where can I find a place to race?

Usually, you could find a local RC club for racing. Or, if you are lucky enough to have big back yard or huge garage, you could also rach there. However, race in the club is always the most fun place to be. You get to discuss and compare with other hobbyists like yourself. Use search engine to look for your local club is always the easiest way to have a taste of the fun.
