WHO Racing 1/32 scale Goodwood Kit Build rules
These are standardised regulations for kits and most Ready-to-Run (RTR) manufacturers (all those included in standard RTR category plus Ninco, Slot.it, Policar and MR Slotcar) eligible to run in the WHO Can-Am class and all WHO Goodwood Revival classes except the RAC TT Celebration.
1. General
Cars must be 1:32 scale models of 1:1 cars suitable for the class being run. All parts must be commercially available. Cars may be driven by two or four wheel drive. No traction magnets allowed. Ballast may be added but must be inside the car. It is expected that cars will be fully decorated inside and out with an appropriate livery… Because style matters!
2. Body
For RTR cars, bodies, windscreens, window glass, interiors and all detailing parts must be used complete and unmodified. Kits must have hard plastic or resin bodies, but may use vacuum-formed windows. All cars should be decorated in a suitable period style and must carry at least three racing numbers.
2a. Cockpit/interior
All cars must be fitted with either the complete supplied interior or a vacuum-formed interior, suitably decorated and with a detailed driver head, plus shoulders, arms & top of steering wheel.
3. Chassis
All cars must use a moulded plastic, cast resin or 3D printed chassis, which may be supplied with the model or sourced separately. 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.
4. Motors & Motor Mounting
All cars must use an unmodified Scalextric Mabuchi S 18k motor, PSR AC6 double-shaft can or PSR AC1 for FF-050 powered cars. For chassis designed to use a motor pod, a genuine Slot.it inline or sidewinder motor pod must be used. Motors may be glued into place. Motor cans in Slot.it pods must be insulated from the circuit rails.
5. Wheels & Tyres
Wheels may be plastic or alloy with suitable wheel inserts fitted. Tyre width and diameter are specified in the class regulations (see below). Any rubber or urethane tyres are permitted. Front tyres can be coated in superglue or varnish to reduce grip. Tyres may be glued and trued. No tyre additives that leave residue on the tyres or track may be used.
6. Gears, axles, bearings and spacers
Cars can use any make of components, but must use a standard Scalextric gear ratio:
● Sidewinder - 11T pinion & 36T spur gear.
● Inline - 9T pinion & 27T crown gear.
7. Guides
Cars may use any standard-depth (not wood track) guide.
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.
10. Lights & wiring
Lights may be required for some race formats (eg team endurance races), so original headlights and tail-lights should remain, if fitted. Additional lights may be added. Original wiring may be re-soldered or replaced. For digital cars, a ferrite man filter must be present between the digital chip and motor – and second ferrite man may be added between the braids and chip.
11. Digital Chip
For digital cars, 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 an C8515 may be tilted or raised to recess the LED. The board on a C8515 or C8516 digital plug may be removed from the plate and fitted in a non-DPR car.
12. Dimensions & weight restrictions
Some classes operate with a maximum rear track (width measured to the outside of each tyre). Richmond Trophy = 55mm. Sussex Trophy = 57mm. No WHO classes currently run with any weight restrictions.
13. Wheel & Tyre restrictions
Kinrara Trophy, Sussex Trophy & Richmond Trophy: minimum diameter 19mm, minimum width 5mm, maximum width 7.5mm.
Whitsun Trophy: minimum rear diameter 20mm, maximum tyre width 10mm.
St Mary's Trophy: minimum 5mm, maximum 10mm.
