Objectives

Due to the format of the scoring, the fastest overall car may not win the overall prize. Please don’t be so focused on the speed of the car, that you miss the overall objectives.

• Parents and Trailmen work together on their car
• It's our goal that Trailmen do as much work as possible on their own car
• Parents provide guidance, direction, coaching, and encouragement, and can perform work where safety is a concern (Each family determines this for their situation)
• Why do we do this?  Perhaps the primary purpose of the Worthy Derby is to provide a time for families to build great shared memories!

Eligibility

• Any Trailman, troop family member, or "Outlaw" can participate.  An Outlaw is our friendly name for other family members, or friends, who are not able to join the Troop as Trailmen, such as a sister or younger brother.  
• Derby cars must pass all the rules stated below 
• While we have no way to truly know if a derby car had been raced in a previous Worthy Derby, in the spirit of the event, we ask that Trailmen build a new car if they've raced one previously.     

Car Dimension Rules

• The overall length of the car shall not exceed the length of the car provided, which is slightly over 7 inches.  We purchase our cars from ShapeNRace.net
• The overall width of the car shall not exceed 2 and 3/4 inches.
• The car must have 1 and 3/4 inch clearance between the wheels.
• The car must have 3/8 inch clearance underneath the body so it does not rub on the track.
• We do not yet have the exact height, but cars greater than 3.5 to 4 inches likely will not clear the race timing display unit at the end of the track.  More to follow - adding this now provide more design info.

Derby Car Weight Rules

• The car shall not exceed 5.0 ounces.   Any car weighing over the 5.0 ounces must be adjusted at weigh-in.
• We recommend testing the weight of your car in the weeks prior.  See: Derby Car Build Equipment Notes for ideas on a scale. 
• The official race scale that is used at car check-in shall be considered final.
• Before passing the car on to the next stage of entry, if the weight is unacceptably low to the racer, they can leave the entry process and make modifications to the car up until the the entry cut off time.
• Basic tools may be available for a parent or guardian to trim excess weight from the car.  We recommend racers bring tools, glues, etc. to make any final modifications.
• While additional weight can be added before the official weigh-in, these must be provided by the racer.   Additional materials to provide more weight will not be provided by the troop.
• A parent or adult guardian must be present with the racer during weigh-in and registration.

Car Modification Rules

• The official pine wood block - PROVIDED BY THE TROOP - must be used. The block may be shaped in any way that is desired.  See: Derby Car Design Basics and Ideas and How to Purchase and Pick Up Your Derby Car
• The axle slots provided on the block of wood must be used to hold the axles.
• The wheels that come with the kit must be used. The wheels may not be cut, drilled, beveled or rounded. You may remove the seams and imperfections from the wheels.
• Wheel bearing, washers, and bushings are prohibited.
• The nail axles that come with the kit must be used.  
• Oil, grease, or silicone spray should NOT be used on the wheels or axles. Only powdered graphite is permissible as lubricant on the axles.  
• The car must be freewheeling with no starting devices.
• The car shall not ride on any kind or type of springs. 

Other Worthy Derby Race Rules

• Once a car passes inspection and is entered into the race, only race committee members can touch it.
• If the car loses a wheel, or is otherwise damaged, the racer shall have 5 minutes to make repairs.
• Each car must pass inspection by the official inspection committee before it will be allowed to compete.
• The Inspection Committee has the responsibility to disqualify those cars that do not meet these rules. 

Race Day Format

• Upon notification, each racer will take their car from the Pit Area to the Starting Gate. The Starter will then position the car at the starting gate, and the racer will take his position at the Finish Line to await the running of the race. Following the heat racers will then be asked to return the car to the Pit area and wait for their next race. 
• In the event a car jumps the track (as determined by the track officials) we will re-run the heat. If the same car jumps the track a second time, but crosses the finish line its time will stand. If it does not cross the finish line it will be awarded a final time of 5.0 Seconds. 
• If there is a problem with the timing measurement of any lap, the race organizers will rerun the lap until a successful timing is achieved. 
• Any car that is damaged during a race or in the transfer of a car to/from either the starting or finishing gate will have 5 minutes to repair the damage, and we will re-run the heat. If the car breaks down a second time during a race but crosses the finish line its time will stand. If it does not cross the finish line it will be awarded a final time of 5.0 Seconds.

Determining Winners

1. Each racer will have at least 4 races. The times will be averaged for each racer and the racer with the fastest average time is the winner.
2. In the event of a tie, a one race run off will determine the winner. A random drawing will determine the two or three tied contestant’s lanes.
3. There will be awards presented for the winning cars (multiple categories such as fan favorite, best design, etc. TBD).
