1. Organising Committee

All references to “standard” within these rules means “standard” on the 1st January 2001. Any subsequent changes to car specifications by the manufacturer are not allowed unless authorised by the Committee.

2. Rule changes 
Rule changes will be determined by a vote of the committee. If the committee is unable to determine a majority decision, the Chairman may choose to place a casting vote but he reserves the right to abstain. In this case the rule change will not be passed.

Viking Standard Technical Specifications

3. VIKING Modification RULES for Standard Class (Box Standard)

Anything not specified is therefore not permitted.
3.1 Car
3.1.1 All cars are allowed to be modified to the Viking ‘standard’ modification specification.
3.1.2 Cars must remain in standard form, except where specified elsewhere within the rules for the class.
3.1.3 A small amount of glue or tape may be used to secure the motor.
3.1.4 A small amount of glue may be used to secure the bearings.
3.1.5 Cars fitted with stub axles may have them replaced with a beam axle.
3.1.6 Cars can have other manufacturer’s hubs and axles fitted within the class but all four hubs must be a matching set. Wheel hubs must not be interchanged between classes. For instance, F1 hubs can’t be used on GT cars, GT hubs can’t be used on Rally cars, etc., etc. Performance hubs, axles, crown gears and spur gear upgrades are excluded from the standard class.
3.1.6.1 Formula 1 (etc) open wheel racing: Maximum front axle width (outside edge of wheel hub/tyre) is 68mm and the maximum rear axle width (outside edge of wheel hub/tyre) is 70mm.
3.1.7 Body screws may be loosened.
3.1.8 Guide Blades: Blades can be hard-wired.
3.1.9 Material must not be removed or added to the car body.
3.1.10 Material must not be removed or added to the underpan.
3.1.11 All original fittings (except mirrors) must be in place, including airfoils at the start of racing. A fair bit of leniency is allowed here at the discretion of race control.
3.1.12 The car must be in a safe condition. This means that there are no loose components on the car that might fall off during the race. The car must be clean and free of excess oil.
As an example, it is good practice to put tape over the screw holes on the underside of the chassis so that a loosened screw doesn’t fall out of the underpan and into the rails causing a short circuit. This can spoil the racing and certainly leads to a delay whilst the errant screw is traced.
3.1.13 Allowable damage. In general, a car must start the race with all its main parts, (wings, driver, etc) firmly secured to the car in the manner it was intended. However, it is reasonable to allow a car to race if the car originally arrived at the track with all parts intact but due to racing accidents a part is not able to be secured back on to the car. For instance, if a wing breaks off the car, the car can continue racing in the current series (for that month). It is not expected that the car owner should have to purchase another chassis or body simply to make the car complete.
The car owner should consult the Committee if the car owner feels that the only way to repair the car is to add or remove material from the car body or chassis. Agreement from the committee must be sought before attempting such a repair as this may make the car illegal.
If a car has been repaired and has had material cut away from the body or chassis without the consent of the Committee then this car is illegal and can not race. See 3.1.9 and 3.1.10
3.1.14 Damage NOT allowed.
If a car is unsafe to drive, ( i.e. could injure a marshal) then the car must be retired from the race, repaired or the driver can take up the option of using a Club car.

3.2 Motor
3.2 Motors must stay within mainstream slot car manufacturers Scalextric, Ninco, SCX, Fly, Carrera, Slot.It, etc. Additionally, manufacturer branded motors must stay with the same manufacturer chassis and must be of the same motor case type. For example, a Cartrix motor must stay with a Cartrix chassis, an SCX motor must stay with an SCX chassis. A long can motor can only replace a long can motor, a Mabuchi S can motor can only replace a Mabuchi S can, etc.
However, original motors aren’t always available so the Club allows a specific selection of replacement motors. Therefore, motors from the Viking Replacement Motor List can be used to replace original motors. The selected motor must be of the same case type. (See 3.2.2)

3.2.1 Eligible motor performance specification:
3.2.1.1 Motor rpm: motors exceeding 22,000 rpm (S-Can) or 18,000 rpm (Long can) [measured at 12 volts] are not eligible in the ‘Main’ and ‘Support’ races.
3.2.1.2 Motor downforce: motors with a downforce of more than 26 gms are not eligible.
The magnetic down force created by the motors magnets is the difference between the (non-magnetic) weight of the car against the weight of the car as measured on the ‘Magnet Master’ scales. Any motor exceeding the allowed magnetic downforce will not be eligible for VIKING CUP (Support races) or the VIKING CHAMPIONSHIP (Main series) classes.

Motors of a higher magnetic downforce or rpm performance may be eligible for the Viking ‘SUPER’ classes.

3.2.2 Viking Replacement Motor List.
An originally fitted motor can be replaced with alternative motor of the same motor case type as per the table below.
Motors of a higher performance are eligible for the Viking ‘SUPER’ classes.

3.2.3 Motor wrappers must remain on the motor can. Any attempt to remove or replace a wrapper, or suspicion of, will result in disqualification.
3.2.4 Motors must not be opened under any circumstances. Penalty: disqualification.
3.2.5 Motors must be standard with no windings added or removed and with the original magnets in place. No shims or substitutes such as glue may be added. It is allowable to shorten a motor shaft so that the shaft avoids touching car body parts or tyres. This is deemed allowable only to allow the motor to run without interference.
3.2.6 The scrutineers may carry out random tests on motors in relation to a range of standard motors and if in their opinion a motor may have been tampered with, the driver will be disqualified.

3.3 Tyres
Tyres may be cleaned between heats with tape only and may not be cleaned with ANY fluids!
3.3.1 Any tyres may be used so long as they fit on the standard hubs/rims. Tyres may be sanded down and there are no minimum restrictions on tyre diameter. The width of the tyres must be standard. (i.e. not expanded, see 3.3.5). The total width of the rear axle must not protrude more than 1mm outside the wheel arch either side unless the original specification was produced in that way.
3.3.1.1  Formula 1 (etc) open wheel racing:  Rear tyres diameter must not be less than 20mm (unless they are less than 20mm as standard).
3.3.2 Any tyre may be fitted to the front hubs so long as it fits on the standard wheel hub as follows:
Width: The tyre width must be equal to the width of the hub.
Diameter: There is no minimum diameter. When measured on a standard hobby slotted flat-bed the front tyres must touch the flat-bed and must rotate when the car is pushed without downward pressure applied by hand.
Front hubs/tyres: Must not protrude outside the wheel arch either side. There is an allowance for any curvature of the tyre to extend outside of the wheel arch. None of the tyre extending outside of the wheel arch must touch the ground.“
3.3.3 Tyre dressings, where used, must be dry and not leave any deposit on the track. Tyre dressings must not take the form of a coating. Goop and tyre traction sticky substances are strictly forbidden. A test may be carried out with a small piece of paper and if this is lifted from the track by the tyre then it is deemed illegal and a caution is awarded. For a second offence, a yellow card is awarded. A third offence will result in a red card and disqualification from the Championship.
3.3.4 Tyres must be of consistent natural texture and must not be injected with any substance or gas or have or appear to have any pneumatic properties. If there is doubt then the scrutineers will not allow it.
3.3.5 Whilst it is accepted that tyres may expand sideways away from the rims, if in the opinion of the scrutineer, the tyres have deliberately been made to expand sideways, they will not be permitted.
3.3.6 Tyres must be black in colour. No other colours are allowed.

3.4 Dimensions
3.4.1 Rear Axle Assembly width: This rule exists to stop wheel hubs and tyres from protruding unrealistically outside of the body work of a slot car.
The distance a wheel hub can protrude outside of the top edge of the wheel arch as viewed from above is zero.
This rule applies to the HUB and NOT the TYRE. The tyre can protrude but must still fit the hub properly. The tyre protrusion will normally be in respect of its natural bulging – not extra tread on the track!
In the case of slot cars produced AS STANDARD with the hub protruding outside the wheel arch then the driver should present the car to the committee for scrutineering and a decision will be made.
Note: Every time a hub is glued on to the axle, removed, glued back, removed and so on, the hubs moves further out because of the build up of glue inside the wheel hub boss that goes on to the axle shaft. This doesn’t mean that a driver can mount the hub outside the confines of the wheel arch and plead that the build up of glue is prohibiting the ability to stay within the maximum width. It does mean you have to source new hubs. For this reason, the “hub flush with top of wheel arch” rule will be strictly applied.

3.4.2 Either brass or plastic pinions may be fitted.

3.4.3 It is not allowable to deform the car body to keep rear or front wheel hubs inside the profile of the car body.

3.5 Weight
3.5.2 Under no circumstances may any additional weight be added unless specified in the class rules.

3.6 Controllers
3.6.1 Any make of type of controller may be used providing it contains no capacitor boosting or smoothing. Controllers must be able to sustain a capacitance check with an analogue voltmeter.
3.6.2 It is the competitor’s responsibility to ensure they have the correct controller plug for the track on which they are racing.

4. Scrutineering 

Club nights:
7:00pm: All cars should be pre-scrutineered on the day (downstairs) before taking the cars up to the track. This will avoid embarrassing questions on the grid!
This is just good sense to avoid delays later in the evening.
When bringing a new car to the club, it is your responsibility to present the car to Scrutineering to get the job done early and avoid disappointment/embarrassment on the grid just before the race starts.
Any new cars or spares not previously used at the club should be brought to the committee’s attention before use. Products will be examined & tested before deciding which race class is suitable.
Please bear in mind that any tuning parts should be from “mainstream” manufacturers eg. Ninco, Scalextric, SCX, Slot.It, etc.
‘PRO’ specification spares are not allowed if they have metal parts. i.e. metal contrate gears, ball race bearings, etc.
Standard metal pinions are allowed.

If you have any doubt about the spec of your car or its eligibility for a particular class then ask the committee at your earliest convenience.

7:30pm: Scrutineering will also take place on the grid (at random) pre race start.

4.1 Scrutineers may make any checks they wish at any time and their decisions will be final.
4.2 Scrutineers may at random, make any check they wish of cars or controllers.
4.3 Scrutineering will be carried out in at least 1of the heats. The Race Controller may decide in advance which heat will be checked prior to the race sheet being prepared and only the committee shall know the chosen heat. may decide in advance which heat will be checked prior to the race sheet being prepared and only the committee shall know the chosen heat.
4.4 The scrutineers decisions will be final and will be given to the committee for judgment.
4.5 The Committee will decide on any action taken over any breach of these rules. This could mean loss of points or disqualification from the entire event of a guilty driver.
4.6 Cars will be placed in ‘parc ferme’ prior to the start of the race heats. Cars must be returned to ‘parc ferme’ until the final heat has finished and scrutineering has completed.

5. Racing Rules

5.1 All starts will be live (power on) from the start line. Dead starts (no power) may be used in the event of equipment failure.
5.2 False starts will be penalised by automatically cutting the track power for the offending lane for 5 seconds.
5.3 The race controller may switch off the track power during a race if he feels a major crash is imminent or on the instruction of a marshal. A short countdown from 3 must precede the resumption of the power.
5.5 Disputed results will be judged by the Committee for a possible re-run.
No re-runs will be given for bad marshalling.
5.7 If a heat is re-run, all the drivers from the original race will take part again. The result of the driver for whom the re-run is staged will be the only score changed. Other drivers will keep their original scores, but it is up to them to determine how well the objecting driver will do!
5.10 Drivers must choose a model of car they wish to race and use it for that days competition. If the car suffers irreparable damage it may be corrected by use of exchange components during race time, or a substitute car of the same type including motor choice. All changes must however, first be cleared by the scrutineers during race time. A substitute car of the same type including motor choice can be made once. If the second car breaks down then a Club car must be used. All changes must first be cleared by the scrutineers or Race Control.
5.13 No unplugging of controllers is allowed until the race is called ‘race over’ and results announced. Penalty:- Yellow Card.’ and results announced. Penalty:- Yellow Card.
5.14 No shouting at marshals is allowed. A yellow card will be given for the first time and a red card for the second. This will result in disqualification from that race. A further offence means disqualification from the whole meeting.
5.15 Disputed results will be judged by the Committee for a possible re-run.
5.16 Re-runs may be awarded if the counting equipment is in doubt or if a car is damaged, de-slotted or baulked by an object that should not be on the track. Problems caused when a car is poorly marshaled do not result in re-runs. A re-run may also be awarded if a track fault develops and is proven subject to the following:-
The affected driver must shout ‘track fault’ or ‘Power’ after which the race control will cut the power to stop the race. The power will then be restored and the lane checked for faults. If no fault is found then the race will be resumed from the current position.
If the car or controller is found to be faulty the driver may not attempt to repair them until the race has been resumed, as it is not the fault of the other drivers. If a track fault is confirmed then the race will be restarted, regardless of how many laps have been completed or the position in the race of the affected driver. The driver affected by the track fault can elect to continue from the point of interruption.
Once the affected driver has called ‘track fault’ or ‘Power’ he must remain calm and not distract other drivers by shouting or wildly gesticulating.
Under no circumstances must the car or controller be touched or removed from the track except by a member of the committee who will check the track for faults. Any club member can attend to the fault if agreed (quickly i.e. with a ‘nod’).
If a track fault is not found then no re-run will be awarded.
5.17 If a driver’s car de-slots and settles in another lane he can shout ‘POWER’. Power will be cut by the race controller, the car replaced in its proper slot, and the race restarted by the race controller.
A driver can not call POWER for any other reason. The driver who is affected by a second car in his car’s slot can not call POWER but should act in a gentlemanly manner so as not to cause damage to the second car. This may mean slowing down or stopping until POWER is called.

5.20 ‘Rolling-start procedure’

a/ Cars ‘grid up’ halfway round the track on a temporary grid below the main Start Gantry. The white lane car is placed a short distance (approx. 500mm) in front of the rest of the grid.

b/ A normal Start Light sequence is initiated and the ‘rolling start’ sequence is active.

c/ After the Start Lights go out, the white lane car is to proceed at a STEADY ‘half-speed’ pace around the circuit until the final straight approaching the main Start Line Gantry.

d/ All other cars MUST NOT pass the ‘pole sitter’ white lane car at any time before the main Start Line Gantry is passed..

e/ All other cars ARE under normal club racing conditions. This rolling half-lap is a normal racing lap for all cars except the white lane car.

f/ When the white lane car exits the bend on to the final straight approaching the main Start Line Gantry, the driver must and immediately go to maximum throttle and continue at full throttle until the Start Line and Gantry is passed.

g/ Once the white lane car has passed the main Start Line & Gantry normal racing procedures prevail for all cars.

h/ Penalties: a minimum of a 5 second penalty will be applied for the following:
– to any car passing the main Start Line & Gantry before the white car
– to white car for NOT being at full throttle on the final straight leading to the main Start Line & Gantry.
– Wilful or repeated actions will also see those drivers receive yellow or red cards.

6. Ungentlemanly Conduct

The following actions set the standard required in order to ensure that racing is fair for all and is in the true spirit of the original friendly nature of the competition
6.1.1 Unplugging
No unplugging of controllers before the race controller declares the race over.
Penalty: Yellow card for each offence
6.1.2 Abusing Marshals
No shouting, swearing or gesticulating at any marshal is permitted by any driver or any teammate of the driver.
Penalty: Yellow card for each offence
6.1.3 Deliberate crashing of cars
If the race observers or race controller deems that a driver deliberately crashes his car he will be disqualified from that race.
6.1.4 Deliberate crashing into opponent’s cars
If the race observers or race controller deems that a driver deliberately crashes his car in order to take off an opponent’s car he will be disqualified from that race.
6.1.5 Failing to allow lapping cars to pass etc.
If a driver is being lapped he must allow the lapping driver a reasonable opportunity to overtake. This should ideally be on a straight section and not on a bend.
Penalty: Yellow Card
6.1.6 Failing, repeatedly,  to race at a competitive speed appropriate to that drivers experience and car performance.
Penalty: Yellow Card
6.1.7 Any driver who receives 2 yellow cards will automatically be excluded from the remainder of the competition and may receive further penalties subject to a decision by the Committee.

8. Miscellaneous

8.2 Marshals
8.2.1 All drivers must marshal races.
Penalty for infringement: Disqualification from previous heat or next heat.
8.2.2 Marshals must be fair at all times. If a car knocks one or more cars off, the offending car must be replaced last. If a car drives into a car that is de-slotted then the de-slotted car must be replaced first. (This is a racing accident)
8.2.3 If a marshal is deemed by the Committee to have deliberately mis-marshalled a car or refused to or chosen NOT to marshal then this person will receive a yellow card.
8.2.4 Drivers must NOT marshal their own vehicles.
This includes stopping your vehicle in front of your driving position, leaning forward to pick up your vehicle, tweaking your vehicle then leaning forward to replace your vehicle on the track. This causes a line-of-sight obstruction for other drivers racing their vehicles on track.
8.2.5 Marshals duties during any ‘POWER-OFF’ period.
8.2.5.1 Marshals should pay attention to their marshalling area and check that their track area is free from the cause of the ‘POWER-OFF’, clear of obstructions and fit to continue racing.
8.2.5.2 Reposition de-slotted cars back to their slot.
8.2.5.3 Marshals must NOT pick up cars from the track unless de-slotted or under request from Race Control.
Penalty: Yellow Card

8.3 Disputes
8.3.1 The Committee will settle all disputes. The committee may call upon any persons deemed necessary to reach a fair decision but only the committee may be present to determine the ruling.

8.7 Any member of the committee who is directly involved in a dispute with his own car loses all rights to settle a dispute. This dispute must be settled by the remaining committee members.
8.8 The committee’s decision will be final in all matters. No debate will be entered into once the decision has been declared.
8.9 Anything not covered in these rules is therefore not allowed. The committee will be the final judges.
