D3 2011 1/24 Retro Can-Am racing class rules (revised version V5, 12-21-09)

1. Intent:

The intention of this class is to provide a class of scratch-built slot cars reflecting the spirit of the mid-1960s racing era, with scale realism and low cost, to attract new and experienced racers and builders.

2. Dimensional Specifications

2a. Maximum Overall Chassis Width: 3.125" (measured across any part of the chassis)
2b. Maximum Rear Tire width: 0.810"
2c. Minimum Rear Tire diameter: 0.8125" (13/16")
2d. Minimum Front Tire width: 0.225"
2e. Minimum Front Tire diameter: 0.75" (3/4")
2f. Minimum Clearance: 0.050" (measured under rear axle including gear), 0.040" under motor can at mounting bracket and and 0.015" ( measured at the lowest, most forward part of the chassis ). All clearances measured with car standing on a flat tech board on its wheels, without guide.

3. Chassis construction:

3a. Chassis type: Any personally-built or commercially available scratch-built chassis conforming to these specifications and to the spirit of the intent statement is allowed. Absolutely no form of pillow block construction (as in individual sheet-metal axle holders soldered into slots cut in any form of sheet-metal support) is allowed.
3b. Chassis Materials: Brass sheet, rod and tube, steel wire, pin tubing and guide tongues are allowed. A folded one-piece, three-sided motor bracket including rear axle carrier is mandatory. The motor must be attached to the bracket with no less than two machine-screws. Other than guide tongues, stamped steel parts and EDM or laser-cut parts of any material are not allowed unless submitted for approval.
3c. Drive type: Inline drive only, with the motor shaft at 90 degrees to the rear axle as viewed from above.
3d. Other than a drop arm, all hinged movements must be oriented in only one direction (i.e. either side pan hinges OR a plumber hinge, NOT BOTH, meaning that a "loose" hinge may not provide movement in more than one direction). Centerline hinges (flexi hinges) are not allowed. No chassis movement, dynamic or induced, may extend the overall chassis width to more than 3.125".
3e. Front axle: A single straight, round  3/32" minimum-diameter one-piece front axle is required, carrying both front wheels. The axle may be fixed or in a tube. NO hinged front wheel movements are allowed (i.e. no "L" arms). Front wheels may rotate independently. No visual obstruction of any kind across either front or rear wheels must be seen when viewing the car from its sides. No "pillow-block" construction is allowed.
3f. Guide: One guide flag centered on the longitudinal axis of the chassis (i.e. no sideways "free float" or offset) is allowed.
3g: No on-board automatic liquid dispenser of any kind is allowed.

4. Motor rule:

4a. Motor type: Unopened, unmodified TSR D3 Spec motor. Motor must be affixed to motor bracket with two screws set inside the pre-tapped M2 locations on the can.
Exclusion Clause: Clear violation of motor-tampering rule will result in permanent exclusion from any Division III participation in any form.
4b. King-track races rules:
Specially numbered motors are randomly handed out to the racer by the raceway owner at time of entry. Unless marked otherwise, the motor(s) number(s) is (are) registered on the entry form at the counter. An entrant may purchase any quantity of motors, but only the motor registered at time of tech inspection can be qualified and raced. Any other numbered motor purchased that day CANNOT be used for racing on the King track at any time present or future. It can however be raced on any other tracks.

5. Body rules

5a. Body style: Bodies must be originals or exact reproductions of pre-1970 Can-Am or Sports/GT bodies by Russkit, MAC, Lancer, Associated, Dynamic etc. No "flattened" or "aerodynamically improved" bodies allowed (i.e. no molded-in spoilers, wings etc that were not on the original full-size car or original mold). Bodies with molded-in cockpits are not allowed even if cut out. Front wheel arches must be cut out. Rear wheel arches may be left closed if the original full-size car ran with closed wheel arches. Bodies must be presentably painted and carry at least three racing numbers, one on each side, and one on the front. No part of the chassis may be seen when looking at the car from its top. Bodies must be molded from material with a minimum thickness of 10 thousands of an inch.

Other bodies must be submitted to The Division III Committee members for approval.

5b. Spoilers and air control:
-Material: clear plastic
-Maximum visible size of the actual material: 3.125" X 0.5".
-Must be flat where visible.
-Must not extend higher than 1/2" from the highest point of the rear fenders.

-No side dams of any type are allowed. -Front diaplanes are not allowed. -High wings are allowed on specific models (Chaparral 2E/2G/2H/2F, Lola T163, McLaren M8C...)

5c. Cockpit: Cockpits must be fully opened following the natural line of the windscreen and body. A separate 3-D driver figure painted in at least 2 colors must be fitted.

NOTE: The use of "speed rubber" tires (regardless of their brand or name) that have a partial silicone content that effectively leave a deposit on the track is forbidden.
The use of such tires during qualifying or racing will cause immediate disqualification of the entrant/racer and a single warning. A second offence will cause permanent banning from D3 racing.

Any matter regarding this class must be submitted in writing to a member of the D3 Board of Directors
