BRAKES

1)      All cars must have at least one operational brake; there is no limit on brakes of multiple tyres. Lay-shaft, hydraulic or cable brakes are permitted.

2)      The brakes must be capable of stopping the car and holding it stationary whilst the engine is running.

3)      Braking system will be checked at the start of the meeting and the scrutineer reserves the right to randomly check any car during the meeting to ensure the brake(s) remain working, any car with a failing brake system will be removed until the fault has been rectified.

FUEL

EXHAUST SYSTEM

1)      An exhaust system must be fitted and effective at all times and for safety reasons must be contained within the confines of the car interior.

2)      Any FG Standard exhaust can be used i.e. (Marder, Monster Truck, Beetle) with suitable outlet adaptation.

3)      No performance enhancement silencers are permitted.

4)      All cars must conform with noise level tests (i.e., <80bd @ 10mtrs or 95db measured 1 mtr above and to the side of the racing surface).

ANTI-ROLL BARS

1)      Anti-roll bars are optional, but if used they must be of an FG design.

FAIL SAFE SYSTEM

1. Cars should have an electronic and mechanical failsafe device that must return the throttle to neutral when activated. I.e. Through loss of battery power and/or loss of radio signal

Please note:- The electronic failsafe on your handset will work (If set up) only if your car goes out of range of the handset or loses radio contact with handset for some reason.

If for any reason the receiver loses power (broken battery or battery wire etc.) and the throttle is open then a mechanical failsafe will stop the car.

Example of a mechanical failsafe on a Marder.

 In the event of a loss of battery power to the receiver, then this spring will return throttle to neutral. The one in the picture is from a ball pen. (Too strong a spring and servo may struggle to open throttle, too weak and it may not return throttle to neutral)

The scrutineer reserves the right to check the failsafe devices are working at any time during the meeting.

WEIGHT

1)      Total ready to race car must not be below 8kg and not exceed 12kg. The scrutineer has the right to randomly check any car at any time during the meeting. Any driver with a car found to be outside of these boundaries will lose any scores achieved up until that point on the day, and will not be allowed to race until their car weight has been rectified. 

COMPLAINTS PROCEDURE

1)      If any driver suspects another driver of running an illegal car regarding engines that cannot be visibly determined without involving stripping down the relevant components, they should adhere to the following procedure.

It will be necessary to log a fee of £50, with the scrutineer. The component of the car will then be examined by the scrutineer in front of another committee member and a decision will be reached. If the component is deemed to be illegal the person logging the complaint has their £50 refunded and the driver in question will lose any points achieved at that particular meeting and will then be banned for the next 2 meetings. Should they wish to appeal this decision, they have 48 hours to log this in writing to the committee. However should it be found to be legal the £50 goes to the driver who had their car stripped down.

ADVISORY NOTE

1)      Any car deemed unsafe for any reason will be excluded from the track until made safe to the satisfaction of the race scrutineer
