Racing Classes
Please note: Members can use the track for practice using any 1/10th scale (or smaller) on-road car.
In order to protect the track we ask that all vehicles used for practice have on-road type tyres
(rubber or foam) and that drivers avoid driving on the grass. Also the area outside the track (car park,
field behind the Kiln building etc.) is NOT to be used.
The Classes - Introduction
Please note: The details listed here are for the classes we generally racing currently.
We're always open to ideas
for other classes if the car you which to race doesn't fit in the classes as described here or you want to
"branch out" to form a more specialised class. All we ask it that the class is suitable for the
track (ie. is for on-road types of vehicles) and that you can get enough drivers interested to make the
class viable (normally around 5 minimum).
During race meetings the cars people drive are split into classes. Each class then has it's own heat/s,
qualifying times and final/s. Classes are based on the car's means of power - an Electric Motor or
an IC (Internal Combustion) Engine, the type of tyres permitted etc. Each class therefore has it's own
set of rules which must be adhered to during the race meetings. During club meetings the cars are not
strictly scutineered after each race. Rather we leave it up to the other drivers in the class to
self-regulate each other with any issues being resolved by the club scutineer or the race director.
The classes we use are generally based on those used in the various national meetings and in particular
those organised by the BRCA. Within each class the detailed rules we use during club meetings are
generally more relaxed than the BRCA rules eg. the bodyshells that can be used, tyres are not restricted to
certain makes and the IC classes can use 5 or 7 port engines. There are other variations and there are
some classes that are not recognised by the BRCA. Please check in the tables below for the classes we race
and their associated rules.
A note about IC : IC cars can also be referred to as "Nitro" or "Petrol" driven. "Nitro" refers
to the Nitromethane used in the fuel used. "Petrol" is sometime used as another way of expressing that
the it's an IC engine that is used. However, engines that use normal Petrol (i.e. as opposed to the Methanol,
Nitro mixture fuels) are NOT allowed.
