This is a very unique class to our area and there are many rules for such a simple class. This is a class that basically should be a 1/10 off road buggy with rubber tires and a late model body. Because this class has so many rules and possible interpretations that the race director may at any time update specs or wordage to protect the class’s integrity with out notice.

Mod Trucks

This class is for 1/10-scale, 2-wheel drive, “off-road” trucks (Examples: Team Associated T4, Team Losi XXXT, Duratrax Evader, Trophy Trucks like the Slash, SC10, Strike etc.). Cars with truck bodies will not be allowed (Example: Custom Works Intimidator or Krenzel’s Terminator).

Transmission: 1 speed only. Must use a gear cover over the spur gear & the pinion gear if a rear motor mount is used.
Drive Train: 2 wheel drive
Chassis: Truck must be based on a conventional 1/10 scale truck platform. This means it must be a production not home built chassis, must have truck length suspension arms, mounts, steering racks ect for that chassis, can not be shortened, lengthened or widened. Modifications to chassis is allowed to move electronics from stock location but electronics must still fit on chassis with out adding extensions.
Suspension: No limits. Well almost. You must retain the stock length arms on all sides, no short arms allowed. Use of aftermarket lowering kits, short shock tower, short shocks will be allowed.
Tires: Rubber and foam tires are both allowed. Tires must be 1/10 scale truck tires. Minimum wheel diameter is 2.2”. Foam tires must have a minimum 1/8” sidewall (see general rules for more foam tire info).

Side Air Dams: Side air dams are allowed. Side arm dam can be no bigger then 16” long and 5 3/8” tall including where you mount it. Side dams can be smaller. All exposed corners must be rounded.

Stock Truck

This class is for 1/10-scale, 2-wheel drive, “off-road” trucks (Examples: Team Associated T4, Team Losi XXXT, Duratrax Evader, etc.). Cars with truck bodies will not be allowed (Example: Custom Works Intimidator or Krenzel’s Terminator).

Body: Must be a truck body. No rear spoilers allowed
Side Air Dams: No side air dams allowed.

-All Classes
- No roll-over antennas
- Bodies must be securely fastened to the vehicle.
- Body must be on the vehicle to have laps counted.
- All cars/trucks must have numbers on them. These are 1/10 race cars, so let’s make them look like race cars.
- Foam tires must have a .125” minimum sidewall. Also, foam tires with excessive chunks missing will not be allowed. If you are unsure of whether or not your tires will pass, ask the race director. The final decision will be left to the race director.
- All cars/trucks must have 4 tires/wheels to race. If one falls off or breaks off of your car/truck, then you must pull off of the track.
- If you miss the start of the race, you cannot join in that race. Your vehicle must be on the track and ready to race when the race starts.
- Track records must come from a Main not form a Heat race. For a new record to be official, the driver is responsible to have his/her car teched after the race. The car/truck can not go to the pits first, it must go immediately to the race director.
- On the final points night we will run one heat race and then the mains. Heat races will not determine the line-up for the mains. The mains will be lined up according to the points. The fastest qualifier in each class will earn the bonus points just like any other night, but the line-up for the mains will still be set by the points. We will throw out each driver’s 2 lowest nights, so the mains will be lined up by the best 7 races. The starting order of the mains will be inverted.
- In the event of a tie, we will go by the number of wins and number of times as a top qualifier. The driver with the highest combined total of the two wins the tie-breaker. If a tie still exists, we will go to 2nd place finishes, then 3rd, then 4th, etc. The tie-breaker will be figured by using all previous events, no throw-outs.
- Make sure that the car/truck that you are driving meets the rules for the class that you are racing in. We will be randomly teching cars on both Saturday and Tuesday night race days. Failing to follow the rules will disqualify you for that day in that class.
- If a car/truck does not fit the rules for the class that it is raced in, that driver gets 0 points for that night (this will not be used as a throw-out).

Racing Rules:
- Frequency clips MUST be used when you turn your transmitter on. Also, clips MUST be returned when you have finished.
- Be ready to race. All racers must be ready to race when the race before theirs finishes. This does not mean that you start to get ready then. It means that when the race before yours finishes, you should be at the track, have the correct transponder in your car, and be ready to race. There will be 90 seconds between races.
- NO reverse allowed. If you have reverse, do not use it or you will be docked a lap.
- Respect others. This is a family atmosphere. Please, refrain from using inappropriate language. Remember that we are here to have fun.
- Try to not yell at the marshals. It is not their fault that you crashed. Once again, we are here to have fun.
- Once your race has ended, turn off your radio & car, remove the transponder & put it back in the charger, remove the frequency clip from your radio & return it to it’s home on the board, set your car & radio on a shelf, and get ready to marshal the next race. Please, do not return to the pit area until after you have marshaled.
- Marshals pay attention and be ready to move. Please, do not sit while the race is in progress. Watch for other cars as you enter the track. Marshals cannot work on cars. Marshals cannot throw cars across the track to be fixed.

- NO Silicone embedded foam tires!!

- Cars/Trucks must not dig up or damage the racing surface

- “Remember – Marshall like you want to be marshalled!

- Even/Odd marshalling rules will be in effect. Race one will be odd number transponders. …Race two will be even transponders.
- Be safe and Have Fun!
- Rules are subject to change. Final decisions regarding legality are up to the race directors.
