 We all want to have fun – and the best way to do that is follow the rules!

All Drivers must first sign up before you are allowed to be on the track, this is strictly enforced

It takes 5 people to make a class - show up with 5 rc turtles and people to drive them and race!

No Drugs or Alcohol allowed on the property.

This is a non-smoking facility.

 General Rules -

Legal battery voltage is 8.40, any battery measuring 8.44 or above is illegal, the .04 difference is allowed for calibration discrepancies or other variances.
If found to be over voltage 8.44 - 8.49 you will be allowed to run off the pack prior to the start of the race, with one re-measurement of voltage, if it is still over voltage that car will not be allowed to compete. The rules infraction is allowed one time per season. The second time over voltage, OR if the excess voltage measures 8.50 or above that driver will be done racing for the season. Keep in mind .01 is not arguable and this rule will be strongly enforced.

Penalties will be issued for not being on the track to Marshall. Any car not on the tech table after there respective heat will be disqualified.

All oval Cars are rolling starts. Electric Mains are also rolling starts.

No car will be driven at any time in reverse of the track traffic. If this occurs, a one-lap penalty will be deducted off the driver’s best time. The use of reverse is illegal in all classes.

Turn marshals may not work on or repair cars.

It is the Drivers responsibility to bring the vehicle to the Tech table immediately following each race. Failure to do so will result disqualification.  

Any violation must be corrected BEFORE the car is raced. If a car passes through "Tech Inspection" and a technical illegality is over-looked, the vehicle is still illegal.  

Any racer may front $50 for tech inspection for any car on the track - if the car is found to be legal the $50 will be forfeited and given to the legal racer.

Oval Vehicle Rules

Tire Rule and Tech Procedure

We are a paragon free facility. Paragon or tire additives with wintergreen oil will not be allowed. Previous paragon odors can be removed with HOT water and dish detergent. You may have to do this a few times. Tires will not be allowed to smell of any type of mint. All tires must be wiped completely clean with a cotton rag and go through tech, even prior to practice. If a car goes onto the race track without passing through tech that car will not race on that particular day, regardless of when this occurs, including practice. If your tires are not wiped dry to my standards, I will wipe your tires clean with a rag prior to being placed on the race track.

1. All tires must be dry.
   2. All tires must be completely free of any mint odor.
