February 2007


All drivers must have a Frequency Key displaying their name, transmitter frequency and channel number clearly marked.

Before a driver can turn their radio equipment on, they must first place their Key on the Frequency Board.

No radio equipment can be switched on during a race day until the driver has registered and then may only be switched on after their Frequency Key is on the Board, prior to their race or practice session.


Every driver is expected to perform marshalling duties

A driver will marshal the race directly after their own unless the meeting director specifies otherwise.

Any driver who cannot or does not perform their marshalling duties, or fails to appoint a substitute on their behalf, will face possible loss of points.

A track marshal is expected to right any crashed vehicle onto all 4 wheels, where the incident took place, facing in the right direction of travel. Track markers that are displaced are to be repositioned.

Any vehicle that is not running or is damaged to the extent that it cannot limp around to the pits must be removed from the track and be brought back to the marshalling point. No other person other than the marshal may go onto the track, during a race, to retrieve a vehicle. A possible loss of points may be incurred for doing so.

Marshals are not permitted to work on or start a vehicle during a race.


No vehicle may be started, repaired, fueled or adjusted on the track.

A pit person may retrieve a vehicle from a marshal and take and take it to the nearest edge of the circuit or to the pits for service, repair or starting.

No vehicle can be worked on in the pit lane. It must be removed from the pit lane first


Always be aware of other vehicles on and off the track. Avoid obscuring driver vision where possible

Nitro engines can be stopped by licking your thumb and placing it over the exhaust outlet, change fingers if it becomes to hot, or by using your shoe on the bottom of the car on the flywheel to stall the engine. Gloves are available for marshals. It only takes a few seconds to stop an over-speeding engine.

Be aware of hot engines and exhausts or rotating parts such as wheels, gears, shafts etc.

Drivers always need to be aware of the potential for damage and injury that can be caused by their vehicle. Most vehicles weigh over 1.5kgs and will reach speeds in excess of 50kph. Ask yourself would you stand in the way of a brick being thrown at you at 50kph?.....Always drive responsibly and according to the conditions.
