Kub Kars

3rd Waterdown Kub Kar’s

Rules, Regulations, Tips and Tricks

~Points taken from Scouts Canada http://www.scouts.ca/hotwheels/leaders.html.

GENERAL RULES

All cars must start by gravity from a standstill, at the starting point. No pushing is allowed. To finish the car whose nose is the first to cross the finish line is the winner. The race official will decide the winner, and if the result is too close to call, a second race maybe run. If any car leaves the track the race can be restarted. If the same car leaves again, the car is eliminated.

KUB KAR SPECIFICATIONS WIDTH:

Overall width including wheels is not to exceed 7 centimeters or 2-3/4 inches. The minimum distance between the wheels is 4.5 cm or 1-3/4 inches.

WEIGHT:

Overall weight is not to exceed 142 grams or 5 ounces.

CLEARANCE:

Clearance between the chassis and the track should be 0.95 centimeters or 3/8ths of an inch.

RESTRICTIONS

Wheel Bearings, washers and bushings are prohibited. The car shall not ride on springs. Details and attachments may be added providing they are securely fastened and do not exceed the maximum length, width and weight specifications. The car must be free-wheeling and may only be propelled by the force of gravity. Kub Kars are subject to inspection by an official inspection committee to determine eligibility.

KUB KAR BUILDING GUIDELINES

Mark your chosen design on the top and the sides of the block. Carefully carve or cut to the desired shape. Sand smooth. Paint, stain and/or finish as desired, preferably with water based treatments. Insert axle through the wheel and force into slots provided. The wheels should spin freely. Racers may wish to lubricate axles and wheels using (dry) powdered graphite. Prefabricated car bodies will not be allowed to enter any of the design competitions.

PERFORMANCE TIPS AND HELPFUL HINTS

To build a fast car, there are several important details to consider:

• First and foremost, is the wheel alignment, which is necessary to obtain a straight smooth run, thereby reducing wheel friction on the guide track rails. Next in importance is reducing wheel and axle friction. This is accomplished by applying a dry lube to the areas along the axle and wheel bearing points. Also you may want to remove any burrs that might occur on the axle or wheel itself.

• Apply several coats of sanding sealer, then sand entire car with a fine-grade sandpaper. Give the model at least two coats of fast-drying paint. When the paint is completely dry, sand with a fine sandpaper, apply a final coat of paint and allow to dry thoroughly. Rub entire Truck with a rubbing compound. Apply a coat of auto wax and rub to a high gloss finish.

• One can carve out the inside of the Kub Kar and insert metal washers or bolts to bring the weight of the car to its maximum. Some feel that if one places the car weight to the end of the car, the stored potential energy in the race will make a faster car.

• Lubrication is the key in many designs. Powdered Graphite may give an advantage.

• One can slightly file or bevel the bearing surface of the wheel to reduce the amount of friction touching the car surface. Check if the axles have “spurs” near the axle head. Grind away the “spur” metal.

• It is strongly recommended that one refrain from using weights which contain toxic levels of lead.

• Details are important. Take into consideration the following: 1) wheel alignment, 2) axle and wheel lubrication and honing, 3) weight distribution, 4) car design, 5) a high gloss finish.

KUB KAR RACE RULES AND RESTRICTIONS

Cars and trucks must remain on their numbered position on the Car and Truck Park Table when not on the track for a race except for repairs at the Pit Stop and when withdrawn from competition.

When the car or truck is in the Pit Stop, its “parking space” must be covered with an “At the Pit” Notice.

If a “numbered” car or truck is withdrawn from the competition, the Official Scorer must be notified immediately and its “parking space” must be covered with a “Gone Home” notice.

Only Race Control Crew will be permitted inside of the roped-off race track area and the Car/Truck parking area.

The Official Scorer has the final decision-making authority in all race disputes.

Drivers may enter multiple Kub Kars and Trucks in the Kub Kar Challenge Event including models from previous years provided the total number is not excessive for the time available. For the final elimination races only one car per Cub Scout is allowed.

KUB KARS CONSTRUCTION SPECIFICATIONS

Kub Kars must conform to the following construction specifications:

Restrictions:

• • Wheel bearings,washers and bushings are prohibited.

  • The Kub Kar shall not ride on springs.

  • Details and attachments may be added providing they are securely fastened and do not exceed the maximum length, width, height and weight specifications.

  • Kub Kars must be free-wheeling and may only be propelled by the force of gravity.

  • Kub Kars are subject to inspection by an official inspection committee to determine eligibility.

  • Drivers may enter multiple Kub Kars in the Kub Kar Race Event including models from previous years provided the total number is not excessive for the time available. The request to enter multiple Kub Kars must be made in advance, and one model must be new for the current year.

  • Prefabricated car bodies will not be allowed to enter any of the design challenges (i.e. best paint, peoples car, etc)
