The Viking Slot Car Club adheres to the following standards: –

We race as a no magnet club, therefore the spirit of any class is to adhere to three basic principles for each of the Championships described: –

  • The magnetic “downforce” of a car must not exceed the grams value stated
  • The motor must not exceed the RPM value stated at 12V
  • The ride height of a car must not come within 1.5mm of the track surface

These principles will be determined by you and verified by scrutineering, specified by item 4 of the rules.

For all races, any overriding specifications for each class will appear on the Calendar page, for example: –

Car (make/model) to be raced
Track voltage
Tyre specification
Chassis specification (in-line, angle-winder motor)
Motor specification/RPM value
Magnetic downforce

 If a class is referred to as “SUPER CLASS”, the applicable car specifications apply, otherwise you should refer to the STANDARD CLASS.

If you wish to race a car that conforms to the specification for that race series, but is not listed, seek agreement from the committee for acceptance.

In all respects, the main rules of the club apply and are only modified by the class specifications or that outlined in the calendar…in other words, the combination of the main rules, together with the class specification and calendar addendums, will determine a car’s eligibility to pass scrutineering and race.

If you are in any doubt, please refer to the Committee for clarification or if any acronyms or descriptions are not understood.

All vehicles will be scrutineered for the deliberate removal of material from the bodywork or chassis, although some tolerance will be given to the tuning of bodywork or chassis components, but only to the extent to aid body roll i.e. the removal of body posts will fail scrutineering.

The complete absence of a wing that would normally be fitted should be avoided. A car may not be accepted to the grid on the first week of the class, if it is presented with a missing wing and which is regarded as a considerable component.

If a wing goes missing in any race for the remainder of the class, the owner should make every effort to fit a replacement wing for the following week’s race. Acceptance onto the following weeks grid will only be granted by the approval of the committee i.e. if a wing is not available or cost prohibitive to replace.

When viewed from above, the fitting of wider hubs than standard is not excused, however a 1mm tolerance may be made for cars whose hubs protrude outside of the bodywork and cannot physically be moved inward. This is at the discretion of scrutineering and every effort should be made for the tyres to not protrude.

For metal wheel hubs, it is a requirement that inserts are installed. This is to ensure that the car can be fitted with apparatus for dyno testing in scrutineering. A car will fail if missing.

At the risk of a car failing scrutineering, the spirit of the club rules is not to find loopholes and seek an
advantage. The spirit of the club is to determine what is meant by the rules and race to a high standard within means.


The spirit of this class is to allow any car eligible to race in the class, to do so with any tuned components, as detailed within the rules, defined by the calendar and with the following: –

This includes: –
Cars manufactured as standard with tuned parts
Cars tuned after purchase
Cars built from scratch

The only exception for a SUPER CLASS car is the use of any motor manufactured by BRM, the Calendar
specification or any motor that is deemed to have contravened item 3.2.4 of the rules.

Examples of a SUPER CLASS car may contain the following components: –
Metal gears
Metal hubs
High performance motors
Ball-race bearings
Alloy axles
Replacement driver platform and glass with a light-weight material such as “lexan”
3D-printed chassis.

BUT, a SUPER CLASS car will not have: –
Added weight or ballast
Firmly glued on tyres to the wheel hub
Wet tyres when brought to the grid to race
Sponge tyres
Parts constructed of paper
Metal chassis.


The spirit of this class is to allow all cars from the main slot car manufacturers, to race in as near to “box standard” as possible, tuned with standard low-cost components.

Like the SUPER CLASS, cars will adhere to the rules, further defined by the calendar and within the following, however the following manufacturers/cars are specifically excluded from the STANDARD CLASS and deemed to be eligible for the SUPER CLASS only: –

Avant Slot; FlyRacing (not Fly), GOM Slot, HSRR, MB Slot, MRRC (Toyota GT1), MSC, Ninco ProRace, NSR, OSC, Power Slot, Proslot, Scaleauto, Sideways, Slot-It, Sprit Racing, SRT, MR SlotCar and any other tuned or conversion.

Examples of a STANDARD CLASS car may contain the following swapped out components: –
Alternative or zero grip front tyres
Alternative or Silicone rear tyres
Motor (a Motor manufactured by one of the SUPER CLASS brands is acceptable, but the RPM value applies)
Interior driver tub or pan (so long as the transfer does not require the cutting out or adding in of material)

BUT, a STANDARD CLASS car, unless specified by the calendar, will not have: –

Any components, wholly or otherwise, specified as allowable in the SUPER CLASS

Metal gears
Metal wheel hubs
Ball-race bearings
Ballast weights
Light-weight bodies
Firmly glued on tyres to the wheel hub
Wet tyres when brought to the grid to race
Sponge tyres
Parts constructed of paper
The original interior tub or driver pan removed
Any lexan or other similar lightweight interior component, unless it is original to a STANDARD CLASS car
Missing or removed bodywork or chassis parts, with the exception of broken wings, mirrors, aerials etc.
