NASCAR Class

1.  Bodies:

A. All cars must use a Scalextric, SCX, Revell/Monogram or Toybiz 1/32 scale NASCAR Winston Cup car body. Body shape or dimensions may not be altered in any way, except :

1. Material may be added to the bottom edges of the body provided .0625" ground clearance is maintained at all points. Material may not be removed from the lower edges of the body except:

2. On Revell/Monogram Thunderbird bodies only, the skirt on the bottom of the right side of the body may be removed to make both sides of the body the same.

3. The wheel openings may be radiused for tire clearance. Material may not be added around the wheel openings to cover wheels and tires.

B. Cars with clear windows must have an interior tray with driver figure as described in the general rules. Blacked-out windows are O.K. If vacuum-formed windows are used they must be clear and an interior tray and driver figure must be installed. - revised 12/4/98 

2.  Chassis, wheels and tires:

A. Chassis must be in-line (motor shaft parallel to the centerline of the chassis)

B. Chassis must have no hinges. 

1. Any feature that serves the function of a hinge is prohibited. 

2. Sliding, rolling, or moving components are prohibited (No shaker plates, etc.) 

3. Chassis may flex, but it must flex as a single unit.

C. Either scratch-built chassis or conversions of production chassis may be used.

D. Minimum tire diameter, front and rear, is .750" (This is not really scale, but has been specified to make it easier to use mass-produced chassis  designed for this tire size, such as the Parma Womp.)

3. Addendum: The general rule requiring that wheels and tires not be visible when the car is viewed from directly above is replaced for the NASCAR class by a uniform maximum width between the outer edges of the wheels/tires of 2.375". This means that parts of the tires will stick out slightly beyond the body on some NASCAR cars. This change will not require anybody to scrap or redesign anything they have already built. It just means that some of you will be able to use a few more axle spacers and move your wheels a little farther out. Also, if you want to reshape the fenders to cover the tires out to the allowable width you may now do so but you don't have to. - revised 12/24/98

Vintage Sports-Racing/Sports-Prototype Class

1.  Bodies:

A. All cars must be clearly identifiable as 1/32 scale models of mid-engined sports-racing or sports-prototype cars first raced between 1960 and 1976. The 1/1 scale car must have started in an organized professional or amateur race to be legal as a body type for this class. The Ford J-car, even though it never actually raced as such, will also be legal. - revised 12/4/98

B. All cars must have injection-molded plastic, resin, or fiberglass bodies. No vacuum-formed or blow-molded bodies are permitted. 

C. All cars must have a clear windshield and windows as found on the 1/1 scale car. (Some cars, of course, have just a cockpit surround with no windshield.)

E. All cars must have all bodywork and aerodynamic devices used on the 1/1 scale car. In the case of cars that raced at various times with various combinations of wings, spoilers, etc, entrant may use any configuration with which the 1/1 scale car actually started a race. 

F. No non-scale aerodynamic devices are allowed.

G. Fender flares:

1. Fenders may be flared to cover the wheels and tires out to the maximum permitted width of 2.5".

2. In the area between the front and rear wheel openings, fender flares must blend into the original body sides no more than 1/4" beyond the edges of the tires.  Fender flares may extend all the way to the leading and trailing edges of the body. (see drawing)

H. All cars must have carburetor/injector, exhaust, and roll bar detail where visible on the 1/1 scale car.

Note:  We are not going to be zealots about E, F, G, and H above.  We do not want to get into a debate about whether some amateur racer ran a wing of a certain height and width on his old McLaren in an SCCA Regional in 1979. As long as wings, spoilers, fender flares, etc. look realistic and in proper proportion to the car and don't, in our judgment, give the car any kind of unfair performance advantage, we'll allow them. This gives you some room for creativity, but keep it within the bounds of reality. Also, we're not going to measure the diameter of your exhaust pipes, but please do try to include the appropriate details in some reasonably realistic-looking form.

2.  Chassis, wheels, and tires:

A. Any chassis design is allowed -- inline, anglewinder, sidewinder.

B. Chassis may have a maximum of one hinge. (Hinged pans, for the purpose of this rule, are considered one hinge, since you can't very well hinge one pan and not the other.)

C. Maximum width between the outer edges of the wheels/tires is 2.5".

D. Minimum tire diameters:  front .700", rear.790" (These dimensions were arrived at by measuring the tire diameters on several 1/32 scale static kits of appropriate cars and using the smallest front and rear diameters found.)

General Rules

(These apply to both classes)

1. All cars must use a box-stock, unopened Plafit Cheetah or Fox motor. Lead wires may be changed. This is the only allowable change to the car's motor and wiring.

2. The sides of the body between the wheel wells may be reshaped so they extend straight downward from the widest point on the body side.  (See drawings)

3. Chassis ( including guide flag), wheels, and tires must be covered entirely by the body when viewed from the top. - revised 12/4/98

Except in NASCAR Class as specified in the NASCAR rules (See rule #3) - revised 12/24/98

4. All cars except NASCARs with blacked-out windows must have an interior tray with an appropriately-painted driver figure consisting at least of head, shoulders, arms, hands, and steering wheel.  The interior tray must fill the entire cockpit opening.

5. Vacuum-formed clear parts and interior trays are permitted.

6. A minimum ground clearance of .0625" must be maintained under all parts of the chassis, including gears. Bodies may be mounted loosely, provided the required 1/16" ground clearance is maintained at all times. - revised 12/4/98

7. Chassis may be constructed of any material.

8. Car must have only one guide flag, which must be mounted on the centerline of the car.

9. Working steering is allowed.

10. All tires must be made of black material. Only black sponge rear tire rubber will be permitted. Any compound will be allowed, provided it does not damage the track or adversely affect the condition of the racing surface.

11. Entrant may send an alternate set of rear tires with each car entered. The race organizers will test both sets of tires before the race and will race the car on the set that works the best.

12. Traction glue is permitted. 

A. Entrant may send along a bottle of glue to be used with his car or may specify that glue not be used with his car.

B. As an alternative, entrant may leave the use of glue to the drivers.

C. Glue will be applied only to the tires, not the track. 

D. Glue must not damage the track or adversely affect the condition of the racing surface.

13.  Minimum front tire width is .25". There is no maximum width on either front or rear tires, provided they fit within the body as specified in rule 2.

14.  No ball bearings are allowed.

15.  Controllers: In the interest of  keeping cost and complexity somewhere within reason, we will apply  the same controller rule that we enforce in our own series. That rule limits controllers to one resistor, located inside the controller handle (double-barrel resistors are OK) and prohibits any kind of chokes, external resistors, adjustable features, micro switches, or electronic circuitry. In other words, a stock Parma Turbo is about the limit of what's allowed. We don't want people to have to buy a Ruddock to be competitive. We will have an assortment of controllers in different ohm ratings here at the track, so if you don't want to send a controller with the car, either specify the number of ohms you want us to use or let us pick the best controller for your car.

16.  There is no limit to the number of cars each person may enter in this event.

17.  There will be an entry fee of $10.00 for each car entered. This will cover return shipping of the cars, plaques/certificates, and other costs of putting on the race.

18.  Prizes will be announced as sponsorship is secured. 

19.  Entries must be received by the following dates: The NASCARs need to reach us by Feb. 13, 1999 for the race on Feb. 20. CanAm cars nust be in by Feb. 20 and will be raced on Feb. 27. Entries will be shipped back on or before March 1, 1999. (Unless we get utterly swamped with entries in which happy case it may take longer and we'll let you know!) - (revised 12/24/98)

20.  Send entries to: 

21.  Each entry must be accompanied by a completed entry form (to be posted soon on the OWH web site and also on the Slots DL.
