MUST READ THIS BEFORE RUNNING Running a nitro kit is fun and easy, but to make this a safe and good experience you must observe a few rules. This kit is extremely fast, easily over 40MPH, and can seriously injure someone if you are not careful. Where to run car? • Any running area you choose must be dry. Do not run car near any water or wet dirt. • Do not run on public streets. It is very easy to have the car run over or damaged by hitting the curb. • Do not operate car in tight confined places.
