General Rules and Guidelines:


General: Only cars, tuning parts and motors from the following manufacturers are permitted:  Ninco, Scalextric, Superslot, SCX, FLY, and Policar, ProSlot, Slotting Plus, Avant Slot, Scaleauto, Slotter, MSC, NSR, Racer Sideways, Thunderslot, Mr Slot Car, Slot Racing Company, Black Arrow and Spirit.  Tuning parts from the stated manufacturers are permitted (unless stated in class rules). All cars must go to the line DRY. Oil or other fluids must not be dropped on to the track. Screws must be secured so that they do not drop onto the track. Gluing in of parts is allowed. Scrutineering of cars and controllers will take place at the discretion of the scrutineer / committee. Lightweight interiors are allowed in Sports/GT and Classic Sports/GT classes only).

All large can (boxer-type) motors must have paper removed from side nearest track, or at least a hole must be cut in the paper wrapper on the underside, exposing the armature for examination.


Chassis and Body: No cutting; lowering; bending or reshaping from the standard for any reason. Lightened interiors that come with the car or are a reasonable representation are permitted, except where stated, Clear Lexan interiors must be painted. Body or chassis may have lugs / exhaust detail removed to help flex. All cars must have all screens and interiors in place, including rear or other wings at the beginning of each heat. These items may be missing only as a result of accidental damage during racing or at the committees’ discretion. All kit cars must be painted/decaled to bring them up to weight.

Wheels and tyres: Must not extend beyond the widest part of the wheel arch. No silicone or urethane/Ortmann tyres. Tyres may be trued and softened, but must be dry when placing on track!

No 3D printed replacement parts, EXCEPT in Sports / GT, BUT limited to the chassis and motor pod.


Bearings & Suspension: Ball race bearings are allowed only in Sports/GT or Classic Sports classes. No magnetic suspension kits.

Guides: May be fettled to personal spec; i.e. sanding leading edge. Guides are open except where stated in class and must fit the chassis/body without modification.

Braid: All braid used must be matted for racing, to prevent strands of wire shorting the track.

Hand Controllers: All hand controllers must be of standard manufacture – i.e. any unmodified hand controller available commercially from any UK supplier. No hand-built controllers or modification of controllers allowed.


Marshalling / Etiquette: When not racing, you are obliged to marshal a section of track. Please be aware that you are responsible for getting cars on as quickly as possible in the event of a de-slot or crash, so ATTENTION NEEDS TO BE MAINTAINED ON THAT CORNER. Normal procedure is to replace the offending car in an accident LAST. The calling of “straight” is only really necessary on three sections of the track – the main straight and the areas on top of and under the bridge. It is NOT acceptable to call “straight” simply because your car has come off and you feel the marshal is taking too long to replace your car. Drivers should not call “straight” under any circumstances unless they de-slot in the three hard-to-reach sections described, in order to avoid damage to yours and other people’s cars. Obviously, there are some weeks when we don’t have enough marshals – unmanned corners can also be seen as an area where straight can be called. It has been decided that drivers calling “straight” unnecessarily will receive a 5 sec penalty at the end of the race. When cars finish a race, they should NOT be left in the middle of turn one after they have coasted to a halt. This obstructs cars that are still racing and can cause an unnecessary obstacle for other competing drivers. If you are marshalling turn one, please remove cars that have finished to a safe place off the track. (Drivers – it would make more sense if you made your car stop BEFORE the first corner after your race has finished). Once you have finished your heat, remain at the drivers’ position until the last driver has also finished.
The following items are banned from trackside and during all races : Food and drink, mobile phones, hands in pockets, cars being repaired/fettled. Marshals should not call "Straight" unless there are 3 or more cars off. 

When initially placing your car on the track to practice or race, please position it on a straight – NOT on a bend or just after a bend… cars already on the track will be tail-sliding through corners!

When it is your heat, please get to the line as quickly as possible. A wooden block will be placed on the start line as soon as the race director is at his post. If you arrive late, you will only get ONE lap to practice.

It is not acceptable in any circumstances to use foul language when it may be heard by a junior member or visitor.

General banter between adult members is tolerable unless it gives genuine offence: we are a club of almost exclusively adult males and familiar with insults and sarcasm that include swearing, but we should behave responsibly.


Championship Rounds The Championship will be decided on the best 5 rounds from 7.  No car sharing – If you do, neither driver will score points for the round. The race controller or marshals on the first bend are responsible for calling for a restart in the event of 3 or more cars (or half the field) de-slotting on the first bend of the first lap (Area up to white line). The “Blue Flag” rule applies as in real racing i.e. if you are being lapped you are obliged to let the faster driver through without hindrance. If a car breaks down during a race/heat, it may NOT be replaced by another car. Attempts by the driver or his allocated mechanic (if possible) can be made to fix the vehicle so that it can continue in that race – The race will not be stopped for repairs to be made.

Points will start at 25, 24, 23, etc.


Any new car issued after 1st January 2023, will not score championship points until the committee has approved it. (Does not include re-paints of existing models).


It is up to the member/visitor to prove that his/her car and equipment are legal.


Please remember, we wish to race under a friendly atmosphere, keeping to the rules will help maintain this.

As a member/visitor, you are obliged to help set up and clear away. There are plenty of jobs to do!
