Indoor Classes

We have some General Indoor Rules that apply to all racers.

Then we have a set of basic rules for each of our classes.

For our next club championship (10 weeks from 9th April 2024) the classes we are running are:

We also have rules for these additional classes that have not been active for some time, but could make a return in future. If you would like to run one of them please get in touch

 

General Rules (all classes)

Lipo Handling

Lipo (lithium polymer) batteries must never be charged at a rate exceeding the maximum instructed by their supplier / manufacturer, and in any case never exceed the club maximum charge rate of 10 amps. Anyone found to be charging at a higher rate will be asked to leave the venue.

Charging of lipo batteries must be carried out in a lipo sack or vault using the correct type of charger.

Tyre Additive

Only tyre additive from the BRCA approved list may be used.

Ride Height

Minimum ride height is  3mm for GT12 and 5mm for all other classes.

GT12 chassis must be sanded and smoothed at the edges to avoid cutting the carpet. Bodyshells for all classes must be rounded off at the wheelarches

Permitted Hopups: Ball races. Oil-filled shocks. Aluminium parts which do not provide a speed/handling advantage or alter the geometry.

No other changes from the kit standard parts are permitted.

Tamiya  M-Chassis Rules

The philosophy: Fair and fun racing. Level playing field. Modest budget. Same motor(s) and gearing for everyone. Chassis and components limited to what you would find in the box of a genuine Tamyia M-Chassis kit (including the ‘R’ variants), plus a small number of specifically permitted upgrades (see below). Don’t look for loop-holes!  Build you car to the spirit of these rules and have fun trying to race your car to the front of the field.

Mardave Rules

These rules are a copy ( with permission) of the very popular Basildon Buggy Club mini rules.

This class is based on the basis on the principals of close, fair, and low-cost racing. Whilst other makes of car can be used, they must be of similar design and construction to the Mardave Mini Assassin range of cars. Performance is limited by the construction, and cars should be run “out of the box,” with minor modifications such as manufacturer produced parts.

The Rules outlined below may not necessarily cover every single aspect of car construction and drivers are required to follow the spirit and intention of these rules if any ambiguity is discovered. If you are in doubt of your car being within the rule set, please ask a Race official to clarify. DO NOT JUST ASSUME MAKING CHANGES TO YOUR CAR IS OK.
