Authorized Competitions

Authorized competitions that are in accordance with course regulations will be held as time controlled speed races. The competition will consist of qualification heats to determine who advances to the final heat. Races will commence upon activation of start signal or signal from race official. R/C Mini 4WD racers will be placed behind start line. Chassis and transmitter switches will be turned on. Racers may push transmitter button upon hearing signal. Racers that fall over or course-out during race will be re-set on course by officials. (Some course regulations may call for retirement from race in this instance). In the instance that a receiver becomes dislodged or R/C Mini 4WD racer becomes inoperable for whatever reason, competitor must withdraw from race. In the event that an R/C Mini 4WD racer catches up to another racer and enters the same lane (lane-change type course) and has its progress blocked, the race officials may decide to reposition the faster racer in front. Mini 4WD Racers will finish upon reaching goal line. Chassis and transmitter switches should be turned off immediately. *Transmitter switches should never be turned on without the explicit direction of course officials. Qualification and final heat ranks will be determined by time or order finished. In the instance that rank can not be decided in the above fashion, the decision will fall upon officials in-charge

Inspection of R/C Mini 4WD Racers

All R/C Mini 4WD entrants must undergo inspection prior to race. If parts are found to not comply with course regulations, these parts must be adjusted in the appropriate fashion. Gear, tire, and other modifications will not be permitted after inspection. Re-inspections may be called anytime during an event. Should an R/C Mini 4WD racer have prohibited parts, all race results for that entrant up until the re-inspection will be made VOID. If prohibited parts are not adjusted to meet course regulations, the participant my not re-enter. In the case that adjustments cannot be made (not enough time, no replacement parts, etc.) to correct parts prohibited by course rules, the participant may enter qualification heats, but results will be for personal reference only and will be voided from race records.

Concerning Disqualification

Participants may be disqualified for the following reasons. Participants are always expected to exercise common sense and courtesy. Employment of parts that pose danger to course, other R/C Mini 4WD racers, or other participants is grounds for disqualification. R/C Mini 4WD racers appearing to have excessive grease or dirt may tarnish course and are subject for disqualification. Making prohibited modifications after inspection is grounds for disqualification. False starting two times is grounds for qualifications Racing in an overly aggressive fashion that poses blatant danger to other R/C Mini 4WD racers is grounds for disqualification. Intentionally turning on transmitters without course officials' permission, blatantly disobeying course officials' orders, or disrupting race event are all grounds for disqualification. Disturbing other participants and disobeying the rules of fair play may result in disqualification.
