WHO Racing 1/32 scale GT Championship & LMDh rules
WHO GT Championship and LMDh (Le Mans Daytona hybrid) cars run to our local interpretation of DiSCA GT4 Clubman Scalextric standards. These guidelines allow limited alternatives to standard parts, to overcome poor availability of Scalextric spares and encourage resilience in these longer-format two and four hour races.
1. General
Cars must be a high-detail Scalextric DPR model from the supplied list. All parts must be commercially available. No traction magnets allowed. Ballast may be added but must be firmly attached inside the car. It is expected that cars will be fully decorated inside and out with an appropriate livery… Because style matters!
2. Body
Rear wings must remain fitted at all times and may be rubber mounted. Minor bodywork trims and details such as mirrors and aerials may be omitted. Bodies and window glass must be complete and unmodified. Bodies may be repainted. All cars should carry at least three racing numbers. The body must be mounted to the chassis using the original fixing locations and methods. Any screws and washers may be used. Body to chassis mounting posts must not be lowered in any way. Tabs and braces may be removed to aid body float.
2a. Cockpit/interior
Original cockpit must be used and include full driver, roll bar and all detailing parts. The cockpit may be lightly trimmed for the benefit of fit and clearances. Sidewinder cars may use vac-formed interior as a Balance of Performance measure.
3. Chassis
The chassis must be an original Scalextric chassis with either in-line or sidewinder motor orientation. PCR chassis are not allowed. No modifications to the motor, axle or guide mountings positions. Minor sanding of the chassis edges is permitted to allow the body to move freely on the chassis. Body mounting posts on the chassis may be shaved or lightly sanded to remove lips and aid body float.
4. Motors & Motor Mounting
All cars must be powered by an unmodified Scalextric 18,000 rpm S-can motor. Motors must not be modified from manufacturer’s specification. Motors must be mounted in either an inline or sidewinder configuration, as per the original model. Motors may be glued in place.
5. Wheels & Tyres
Wheels may be original Scalextric or 17.3mm diameter Slot.it plastic wheels, fitted with appropriate Slot.it inserts. All wheels must have tyres. Tyres must be made of black rubber or urethane. Tyres may be glued, trued and coated, but must be dry to the touch at the start of each race. Maximum width of rear tyres is 11.5mm. When viewed from above, tyre edges must be contained within the widest point of the wheel arch.
6. Gears, axles and bearings
Gears must be standard Scalextric plastic items only – 9:27 for inline or 11:36 for sidewinder. Axles are free, but must be solid steel. Bearings and spacers are free, but only concentric plain bearings are allowed. Ball bearings are illegal.
7. Guides
Any standard-depth guide can be used together with an adapter (eg Johnny’s Workshop, Pendles or Andi Rowland).
8. Braids
Any braids may be used. Braids must be cut so they do not protrude beyond the rear of the guide flag. Braids must be replaced if they become worn or frayed.
9. Lights & wiring
Lights are required for the endurance race formats, so original headlights and tail-lights should remain, if fitted. Additional lights may be added. Original wiring may be re-soldered or replaced. A ferrite man filter (or new resistor set-up) must be present between the digital chip and motor – and second ferrite man may be added between the braids and chip.
10. Dimensions & weight restrictions
There are no width or weight restrictions, except that tyre edges must be contained within the widest point of the wheel arch when viewed from above.
11. Digital Chip
A Scalextric C8515/6 EasyFit digital plug (any version), Scalextric C7005/6 retro-fit chip or Slot.it SP15 (any version) can be used. The board on a C8515 digital plug may be tilted or raised to recess the LED.
