GENERAL RACING RULES
The General Racing Rules and guidelines will be adhered to when competing in the Allstar R/C Dirt Series. It’s understood that some race events and venues holding races promoted or sanctioned by the Allstar R/C Dirt Series may revise some of these rules to better align with their track or program requirements.
SAFETY
Safety is the number priority of the Allstar R/C Dirt Series. If you see something unsafe please let one of the ARCDS officials know.
- All events require an adequate number of fire extinguishers whether the classes are electric or nitro. The utilization of Lipo batteries and race fuel present flammable dangers and it’s important that safety be at the forefront for each participant and event.
- Only drivers running their car, are allowed on any area of the driver’s stand.
- No littering, please clean-up after yourself as well as any trash in your immediate pit area.
- Only closed toe shoes are permitted on the track. No sandals or flip-flops allowed on the track.
- No smoking, vaping, food, canned drinks or spitting on the race track!
RACE PROCEDURES
- All qualifiers will be (4) minutes and mains will be (5) minutes in length.
- SC Late Models & 1/8th Scale Late Models will run (4) minute qualifiers & (4) minutes mains
- Starting procedure will vary, its our goal to have rolling starts in the all classes including Street Stocks, Winged Sprints, Non Wing Sprints, SC Modifieds, EDM and 8th / 10th Late Models. If we cannot get a clean start after two attempts we will resort to typical IFMAR starts. The starting procedure will be addressed at each drivers meeting.
- All drivers are required to attend the drivers meeting.
- If a pit lane is available cars must enter and exit the racing surface via the pit lane at all times.
- No stopping on the race track at any time, go to the infield to set steering trim and etc.
- Any cars damaged and placed in the infield will remain there until that race is over
- (Do not run across the track during competition to retrieve your car).
- All cars will be made available for tech inspection before and after race if required by the race director or tech inspector (battery, motor and tire rules will be strictly enforced).
- Once a car has gone through pre-race tech it must go directly to track not back to pit area.
- All racers must have a personal transponder (2) or (3) wire AMB transponder; you may participate without one but will not be officially scored.
- See a ARCDS official for the purchase or possibility of a loaner transponder for the days events.
- You MUST run (1) of (3) qualifying rounds in order to qualify for the lower mains during the point series.
- If you are substitute driving for a particular racer, you must have ran (1) qualifier in order to score points. A driver cannot gain points by using substitute drivers.
- If you substitute drive, you must present an entry fee to the track and series. You will be treated as an additional entry to the race program.
CORNER MARSHALLING
- If you are running multiple classes its YOUR responsibility to find a corner marshal to cover your position.
- Just because you race (4) classes does not diminish your responsibility to marshal. Please locate a volunteer or I’m sure we have some that would accept a small donation to corner throughout the day for you.
- Racers will not yell or curse at corner marshals, if there is an issue let the race director resolve the problem.
- Turn marshals are prohibited from working or repairing cars.
- All drivers must turn marshal the race immediately following their race in the position based on the starting position of their qualifier (i.e. car number). If you are physically unable to corner marshal let a ARCDS official know so that an alternate can be in place before the next race begins.
- No smoking, vaping, or playing on cell phones while marshalling, please respect your fellow racers and remember they will be marshalling for you too.
GENRAL RULES OF COMPETITION
- No Traction Control Devises Will Be Allowed, This Included Gyros, Traction Control Devices Built Into Receivers such As The Specktrum AVC Equipped Radios. This will be checked!
- All cars will be 4-wheel independent suspension, single speed transmissions only.
- For turn marshal safety all cars must have a front bumper that is made of a shock absorbing material such as nylon, delrin, plastic, kydex etc.
- All power, radio equipment and weights must be in a secured and fixed position and not moveable during a race.
ROUGH DRIVING
- Intentional wrecking of other competitors in not permitted.
- 1st offense – Warning From Race Director
- 2nd offense – Stop and Go Penalty on Pit Lane
- 3rd offense – removed from the race event
RACING YOUR COMPEITION WITH RESPECT
- Each racer controls their own cars and are responsible for the control of their vehicle. If you are multiple laps down and the leaders are lapping you please pay respect for the race that is currently being decided.
- There are some days that everything will go right and others that don’t; remember your competitor may be multiple laps down to you the following week.
- Intentional wrecking of the leaders while many laps down is not permitted.
- The Race Director has total control of the race. All competitors will race by the same rules in each class.
- If you have a disagreement with your fellow racer; see the race director so that he is aware of the situation and can work a solution that best suites you, the track and our other fellow racers and our spectators.
- Racing is a high emotion sport and while we embrace spirited battles we are supposed to be enjoying a hobby were all passionate about.
Race directors will have the final decision concerning rules enforcement. The rules have been developed in the interest of what’s best for the racers by the racers. All race formats and technical questions should be brought to the attention of the race director and technical inspector prior to the race being run. If the rules “doesn’t say you can, then most likely you CAN’T!). The motor and battery rules will be enforced; this is to create a level and fair playing field for all competitors and to control the cost associated with R/C racing.
Lastly, improper behavior will not be tolerated. There will be no yelling or cursing, any comments directed at corner marshalls will not be tolerated. There will be no track cutting, spinning doughnuts in the infield or wrecking into the pipes on purpose because one is mad at the outcome. That can injure any of the corner marshals in the infield. Ultimate RC has worked to develop a family oriented atmosphere where friends and family can have fun and spirited competition. Any behavior detrimental to a positive environment for the children and future of R/C racing is not acceptable.
Drugs are prohibited and alcohol should not be consumed during the race events.

IF YOU WANT TO HAVE FUN IN A CLASS WHERE DRIVER AND SETUP ABILITY IS KING, YOU HAVE FOUND THE RIGHT DIVISION.
Because the cars are equal you need to make passes cleanly. Driving through the car in front of you in not considered a clean pass. Just because your faster does not mean dump the car in front of you. A slower car running the bottom is hard to pass! Work hard, race hard but importantly respect your fellow competitors!!
“IF IT DOES NOT SAY YOU CAN—YOU CAN’T”

RULES ARE SIMPLE, THIS CLASS IS MEANT TO BE “FUN” ALLOWING FOR CLOSE COMPETITION ON EQUAL GROUNDS FOR ALL. NO SECRETS OR ‘VOODOO’. IF YOU WANT TO HIDE YOUR CAR OR RUN SOMETHING THAT COMPETITORS CAN’T RUN. THIS IS NOT THE CLASS FOR YOU. IF YOU WANT TO HAVE FUN IN A CLASS WHERE DRIVER AND SETUP ABILITY IS KING, YOU HAVE FOUND THE RIGHT DIVISION.
Because the cars are equal you need to make passes cleanly. Driving through the car in front of you in not considered a clean pass. Just because your faster does not mean you dump the car in front of you…… A slower car running the bottom is hard to pass! Work hard, race hard but importantly respect your fellow competitors!!
“IF IT DOES NOT SAY YOU CAN—YOU CAN’T”
