True Scale Rules

 

Rules applied to all True Scale Classes
 
Only production H-Bracket chassis are allowed. The following modifications may be made to any of legal H-Bracket chassis.
 




·       The front axle hanging systems of these chassis are typically weak and subject to bending. Fabrication of a custom front axle hanging system is allowed.

·       The H bracket may be stiffened by using piano wire or other material. The stiffening material may be soldered or attached using an adhesive substance such as JB weld.

·       Side and front pans may be added

·       Axle hanger holes may be reamed to fit the American bushings/bearings.

·       Bearings/bushings may be secured with super glue, other adhesives or soldered

·       Bolt holes may be reamed accept American bolts

·       Cooling hole may be cut under the motor

·       The 4 small “bump ins” in the center section of the chassis may be removed by filing away the material between them just enough to allow for the inner part of the side pan to sit flush on the center section.

·       No other chassis modifications are allowed unless shown for a specific chassis in the section below.

·       Tires must be black and centered in the wheel openings

·       Full interior tray with painted 3D driver figure is required

·       Two numeric decals are required. Three are preferred

·       Wheel inserts are optional but encouraged

·       Any major body piece such as a wing, if lost due to a mishap, must be reattached prior to the next heat

·       All motors must be sealed (no motor modifications are allowed). On 16D type motors, gold dust or equivalent brushes are allowed

·       The guide flag must not be visible as viewed from the top (exception Cobra/Corvette Challenge class)

·       Front tire width must be .4”. They may not be tapered but may be painted or hardened with super glue or nail polish to reduce rolling resistance. Front tires may not extend outside of the bodywork (although inserts may extend outside the bodywork)

·       Track Clearance – Front .055”, Rear .055”

·       Wheel wells may not be cut. The exception is for the TA2 and Historic Trans-Am (See rules specific to these two classes in their appropriate section regarding wheel well trimming and fender flares)

Gran Sport
 
Gran Sport bodies are typically 60s sports cars. The goal will be to include cars that have the same wheelbase as the True Scale Can Am cars so that a single chassis may be used for either class. The following bodies will be allowed:




·       Ford GT-40

·       Porsche 904

·       Porsche Carrera 6 (aka 906)

·       Porsche 917

Track:
Rear track Can Am/Gran Sport may extend beyond bodywork and if so is limited to 3.17 inches
 
Cobra/Corvette Challenge
 
Background:
 
The Cobra/Corvette challenge (CCC) class will be based upon the KISS principle. The place to start is with the 289/427, 1/24th scale Cobra. This model has the same wheelbase as the True Scale Can Am cars. The Cobra is quite narrow but can be “stretched” to fit an unaltered True Scale Can Am Chassis. This class is meant to re-create early Cobra/Corvette racing, therefore cars will be limited to 1953-1967 model years. In order to promote “competitive diversity”, bodies with approximately the same wheelbase will be selected and “stretching and/or wheel flares will be allowed (but not required) to facilitate tracks that are equal. Again, to promote simplicity, the same chassis may be used on Can-Am, Gran Sport and Cobra/Corvette challenge cars.
 
Bodies:
 
Only plastic bodies are allowed (no resin cars). Cobras may be 1/24th scale. Corvettes may be1/24th or 1/25th scale models with the exception of the 53 Corvette for which only the 1/25th scale version is allowed. Only replicas of cars for model years 1953-1967 will be allowed.




·       Bodies may be raised to facilitate wheel clearance

·       Wheel openings may be enlarged to facilitate wheel clearance

 

Tires:




 

·       Front tires are to be a minimum of .85 inches in diameter

·       Rear tires to be a minimum of .925 inches in diameter

 
Motor:
Only Deathstar and Proslot PS-2002 SpeedFX 16D balanced motor (sealed) are allowed
 
 
Track:

·       Front tires may extend beyond bodywork as viewed from above but track is limited to 2.90 inches

·       Rear track may extend beyond bodywork and if so is limited to 3.17 inches

 
Miscellaneous:

·       Guide flag may extend beyond the front bumper as much as a quarter inch as viewed from the top.

·       Cobra windshield and windscreen are flimsy and may be replaced by a custom windscreen made from any transparent material. Some Corvette convertible windscreens are flimsy and hard to mount and may be replaced by a custom windscreen made from any transparent material.

 
Sports Car
This class includes contemporary limited production and production based closed sports cars (no convertibles or sypders are allowed). The class specifically excludes all cars included in the GT1 class (see above for GT1 list of legal cars).
Bodies:
 

·       Wheel wells may not be trimmed for tire clearance

·      Bodies may not be cut down but may be raised to accommodate tire clearance

·      Front and rear glass must be used

·      Maximum body width at the front and rear openings may not exceed 3.25 inches

 
 Approved bodies are as follows

·       Ferrari Modena

·       Ferrari Testarossa

·       Ferrari F50

·       Ferrari F40

·       Ferrari 458

·       Ferrari 430

·       Audi R8

·       Jaguar XJ220 (1/25 scale only)

·        Ford GT (not the Ford GT40)

·       Porsche 918

 

 

Bodies not on the approved list will be considered, however, please contact the track owner prior to the build. In the interest of competitive diversity, long wheelbase cars such as the Ferrari 599 are excluded from the class. The intent is to be able to use a Tran-Am chassis for cars in the Sports Car class.
Tires and Tracking:




·       Front wheel diameter shall be at least 15/16 inch

·       Rear wheel diameter shall be at least 1.0 inches

·       Rear or front tires may not extend outside of the bodywork (wheel inserts excluded)

Motor:




·       Only Deathstar and Proslot PS-2002 SpeedFX 16D balanced motor (sealed) are allowed

Note that the original post has been edited to incorporate all changes enumerated below.

 

I was looking at the rules and found that one was a typo, one needed to be clarified and  a couple of others changed.

Below are the corrections/changes

 

In the section entitled Rules applied to all True Scale classes - Track clearance should be .055 inches front and rear  Also, wheel wells may not be cut. The exception is for the TA2 and Historic Trans-Am cars (rules specific to these two classes are specified in the appropriate section)

 

 

For Can-Am and Gran Sport cars. Rear track is limited to the outside edge of the rear fender. If the outside edge of the fender is less than 3.17 inches, then the tires may extend beyond the bodywork but track is limited to 3.17 inches.

 

In the list of GT1 approved bodies - Instead of Charge Mazda 767B, the rules should read Mazda 767B or 787B.

 

That's all for now. I will update the original post sometime soon
