Procedure

1. All cars must be registered before the race. There is no registration on race day. 

2. When registering, the cars must meet all specifications for size and weight (see below). 

3. Cars are assigned a number by the computer system. Scouts can choose a name for their car to be displayed during the race. 

4. Cars will race against others from their own den. Each car will go down the track four times, once per lane. 

5. All times are accumulated and the lowest overall time will determine the winners from each den. 

6. The top cars from each den will then compete against each other to determine the Pack winners. 

7. After cars have raced in den races, unless they are first in their den, they may be taken home. 

The Basics

1. The race is open to registered Cub Scouts only. 

2. Only cars made on the official, supplied pinewood box may be used. 

3. Cars must have been made during the current scouting year. 

4. No loose materials of any kind are allowed in the car.

5. If a car is damaged during the race, the owner will have 5 minutes to make repairs and the car must be weighed again. 

6. Once a car is registered, only the Derby Committee may touch the vehicles. 

Size & Weight

1. Width shall not exceed 2-¾ inches (including wheels).

2. Length shall not exceed 7 inches.

3. Weight shall not exceed 5 ounces.

4. Height shall not exceed 3 inches. 

5. Minimum space between the tires must be at least 1-¾ inches to clear the center guide strip. 

6. Minimum distance from the bottom of the car and the track shall be a minimum of ?” so the car will clear the center guide strip.  

7. The car’s front end cannot protrude beyond the starting pin (no v-shaped or similarly shaped fronts). 

Wheels

1. Axles, wheels, and body shall be from the materials provided in the kit. 

2. Wheel bearings, washers, and bushings are prohibited.

3. No lubricating oil may be used. Axles may be lubricated with powdered graphite or silicone.

4. The car shall not ride on any kind of spring.

5. The car must be free-wheeling, with no starting devices.

6. Axle location cannot be moved on the car.

7. Wheel width and diameter should not be adjusted.

   1. Lightly sanding and/or polishing the tread of the wheel to remove burs is allowed as long as it does not reduce the diameter below the allowable level.

   2. The wheel tread width may not be less than .275”.

   3. The wheel diameter may not be less than 1.175” or greater than 1.200”.

   4. The Derby Committee has the ability to measure wheels if there is reason to believe the wheels have been altered.

8. Cars can ride on three wheels and axles can be bent to accommodate this.

   1. Be mindful that if a wheel is raised too high it can make the car susceptible to jumping the lane.

      1. If a car “jumps the lane” but does not interfere with another car then the car will automatically get a 10 second time for that heat. 

      2. If a car “jumps the lane” and does interfere with another car then we will run that heat again. 

      3. If a car “jumps the lane” more than 2 times it will be disqualified.
