Welcome to CRCCCC. This is your handbook that details our Constitution and a set of simple rules we expect all club members to abide by.If you have any questions then please feel free to speak to any of the committee.

Club Constitution

Constitution and Rules for 2014, Updated November, 2013


The club shall be known as Cambridge Radio Controlled Circuit Car Club or CRCCCC.


The club shall encourage the racing of radio controlled model cars and provide facilities and organisation to that end.


Membership shall be open to all and will commence on payment of membership fee. All members have the right to attend and vote at the AGM.

Equal Opportunities

The club aims to treat all members fairly and equally, taking into account any special needs that people may have. The club will not discriminate against any potential club members on any grounds.

Financial Year

The club subscription period is from 1st January to 31st December.


The officials of the club shall also be members of the club. The committee shall consist of the following as a minimum – Chairman, Secretary and general committee member.

The committee will carry out the general management of the club. The club shall seek annual affiliation with the sports governing body, the BRCA, and the clubs rules are set so that they follow the principals set out in the current BRCA handbook.

Advance notice of the posts available will be provided to all club members. Any nominee’s or officers who wish to continue their role must express their interest to the nominated co-ordinator no later than 30 days before the AGM.

The new committee will perform its duties from election at the AGM until the following AGM. If any committee member decides to stand down from his/her role before the year finishes, the remaining committee will decide to either hold the post vacant until the new committee is elected, or elect a new committee member for the remainder of the year.

The committee shall pay the same race fees as other club members.


The AGM will be held annually between the BRCA AGM and the end of the year, to be a maximum of 14 months after the previous.

Changes to either the club’s constitution or the rules may be proposed for consideration at the AGM. Changes proposed by any club member must be submitted in writing to any committee member no later than 10 days before the AGM. Proposals will be voted on at the AGM, only club members may cast a vote. The AGM will include:

Report by the Chairman outlining the clubs intentions for the forthcoming year

Report by the Secretary outlining the current state of the clubs finances

Opportunity for the club members to publicly raise any feedback or concerns on how the club is managed

Election of the committee for the following year

Dissolution of club

Dissolution of the club shall require a two-thirds majority vote at a general meeting at which not less than half the membership is present. Should the club be dissolved the committee shall realise the assets and funds shall be distributed equally between paid up members. Any outstanding loans made by members to the club will be repaid before distributing funds.

CRCCCC Club Rules

All racers, whether club members or not, are expected to abide by the rules as set out below

1)      All racers are expected to help set up and pack away the track, tables and chairs.

2)      The tables are provided by the Community Centre and must be covered by a towel or other cover and must be left clean and tidy. Because of previous complaints by the Community Centre, soldering is not permitted on the tables provided.

3)      All racers will dispose of their rubbish in the bins provided.

4)      Smoking is not allowed in the hall.

5)      CRCCCC is not responsible for any loss or damage to the racers equipment or personal injury, no matter how caused. For details of Public Liability Insurance, refer to the appropriate section in the current BRCA handbook.

6)      Race Fees will be set for the current year. Race fees may be varied for special events and reviewed during the year if the hall hire cost increases. When driver numbers fall such that the standard race fee does not cover costs, variable race fees per meeting, up to a maximum level, may be levied to ensure the hall hire and consumable costs are covered.

7)      Membership Fee will be set on an annual basis.

8)      Racers may become a member part way through a year and pay a pro-rata amount of the club membership as follows; April – June 75%, July – September 50%, October – December 25%.

9)      All members of CRCCCC shall join the BRCA. Proof of BRCA membership may be asked for if a CRCCCC member does not join the BRCA via the club. The BRCA insurance covers potential new members for up to 6 weeks (or 3 meetings) without in additional premium. So a new driver can race 3 times without joining the BRCA or Club. After this, they must pay to join the BRCA and the club Membership Fee as above. Note that the BRCA will process memberships received after the 1st November as running for 14 months (i.e. until Dec 31st of the following year).


10)  Races will be sorted to provide heats with drivers of similar ability, within the restrictions of numbers of racers, driver crystals and heat types. Touring car heats and finals are always 5 minutes duration.

11)  In the event of an excess number of racers wishing to compete, entries will be permitted on a first come, first served basis – regardless of membership status or ability.

12)  Competitors are encouraged to purchase AMB personal transponders to speed up racing. Competitors without PTs will be sorted into one heat, regardless of driving ability.

Good Driving Manners

13)  Heats have staggered starts, so you are racing the clock, not directly racing the other drivers. All drivers get 5 minutes racing time from the time you personally start the heat. Therefore, it makes sense to avoid crashing into other drivers.

14)  If another car is faster than you, then move over to one side to let it past. If you do so carefully you will not lose any significant time. The best way of doing this is to run wide at the first available slow corner and let the faster car have the inside line.

15)  If you are coming up to lap a slower car, then you should give the other driver the chance to move aside at a suitable corner. If you held up for half a lap, it is reasonable to shout out “lapping car #” or “lapping red Alfa” as a reminder.

16)  Cars race for position during the finals when the cars are on the same lap. If you are racing a car that is on the same lap or even if the other car is one lap in front, then just concentrate on driving your race. If you are lapping or being lapped for a second time in a final then the guidelines above should be followed. In a final, you are fully entitled to drive on the racing line to prevent the other driver getting past. If the other car gets the nose of their car ahead of yours then they have the place and you should give way. Remember that the overtaking car has the responsibility to overtake cleanly – barging into the car in front is bad driving and will be penalised.


17)  Marshals should only cross the track when they can do so without impeding circulating cars. When you get to the parked car, try to stand in the “islands” to avoid being hit by other cars.

18)  When placing a car back on the track, position it to the side of the track where it is unlikely to be hit by the other cars and facing along the track so that when it sets off it will not take out passing cars.

19)  Marshals should stay alert to the track area in front of them at all times. When marshalling the bend near the timing loop, avoid lifting cars over the loop bend and so losing the driver a lap.

Car Specifications and Safety

20)  Cars must conform to the BRCA general rules. In particular, note the following extract from Rule 4, Safety “In the interest of safety, any battery packs(s) carried on a model car, must be able to be disconnected quickly without the use of tools in an emergency. Direct soldering is not allowed”. Drivers should note the BRCA advice on charging LiPo cells attached as Appendix 1 and place LiPo cells in a charging sack while charging.

Touring Car Specifications

21)  The class of cars catered for are basically the BRCA Super Touring electric powered 1/10 scale saloon cars. All cars should comply with the BRCA rules with the following exceptions;

a)      Bodyshell choice is more open; you can use any 190mm Saloon or GT shell.

b)      Only rubber tyres may be used, mini pin or foam tyres are not permitted.

c)      Motor choice is restricted to (i) commercially available “stock” 27-turn rebuildable motors with solid bushings (ball bearings are not allowed), (ii) 17.5-turn brushless motors used with “no timing on-the-fly” speed controller (sometimes called “blinky” mode) or (iii) 21.5-turn brushless motors used with any speed controller with any settings.

GT12 Car Specifications

22) Generally following the BRCA GT12 national circuit regulations. 1-cell LiPo with “no timing on-the-fly” speed controller (sometimes called “blinky” mode) and any 13.5-turn brushless motor

23)  BRCA approved tyre additive is permitted and the “non-oily” items listed below. Drivers are required to dry the tyre to ensure that no tyre marks are left on the carpet”. The additive list at time of update is:
a) Spider Grip Green X Strong (SGSX-125) – silver can, ‘carbon effect’ label, ‘green spider logo’
b) Spider Grip Blue Strong (SGBS-125) – silver can, ‘carbon effect’ label, ‘blue spider logo’
c) SXT 3.0 Traction Compound (SXT3) – translucent white bottle, black cap & label, sponge applicator.
d) Corally TC2 (Jack the Gripper) Silver can – pink writing (13779)
– Black plastic bottle with sponge applicator (13742)
– White plastic bottle with foam applicator in lid (13747)
e) LRP Top Traction (Blue Factor) White can – blue writing (6501)
f) Nosram Traction Additive ‘Carpet’ – Black label on white bottle (96010)

Appendix 1 Charging LiPo Cells – Extract from BRCA Regulations

Any rechargeable battery that is currently on the market has a risk of explosion, fire, and smoke emission if not handled properly. Lithium (Li-Po) batteries need to be treated with a lot more care and respect than NiMH cells. The principal risk is fire, which can result from improper charging, crash damage, or shorting the batteries, and this can be difficult to extinguish. Fire occurs due to contact between lithium and oxygen in the air. It does not need any other source of ignition or fuel to start, and burns almost explosively.

These warnings can be a little ‘scary’, and they should be as Li-Po packs can be very dangerous if not handled correctly.  The following precautions should help you enjoy using Li-Po batteries without having a major incident.

General Precautions

Only charge Li-Po batteries on a charger specifically design for Li-Po batteries using the industry standard CC/CV (Constant Current/Constant Voltage) charge profile.

Always ensure you use the correct charging voltage for the cell count.  2S LiPo batteries may be charged to a maximum of 8.40v.

The maximum charge rate should be 1C, e.g. 3.2A for a 3200 mah. pack and peak voltage must not exceed 8.4v. For best charging, low charge rates should be used where possible.

Double check the charge voltage (or cell count), mah, and current before each charge.

Never leave charging Li-Po cells unattended (at any charge rate).

It is best to charge Li-Po cells in an open space on a non-flammable, non-conducting surface (such as a bare cement floor, brick or quarry tile).

Check your charger for safety.  After charging, check the battery with a digital voltmeter, the voltage for a fully charged pack should be between 8.32V to 8.45V.

The minimum safe discharge voltage is 5.0V (2.5V per. cell) when under load, or 6.0V (3.0V) per. cell when not on load. A number of the electronic speed controllers have a Li-Po feature built into their software; make sure that this has been enabled.  Otherwise fit a Li-Po cut-off device.

Use connectors that can not be short circuited, or use silicon fuel tube to protect exposed connections.  Under no circumstances should the ESC wires be soldered directly to your battery.

Do not short the battery as it may catch on fire.  If you accidentally short a battery, place it in open space and observe the battery for 10 minutes.  It may swell up and possibly even catch on fire.

Cell balancing is a way of ensuring your Li-Po will deliver the maximum performance and capacity over a prolonged period of time, although some manufacturers claim that it is not required with their batteries.

Li-Po packs are designed for operating temperatures up to 40°C and under no circumstances must they become hotter than 60°C.

If a pack is involved in a crash or is otherwise damaged, remove the pack from the model and inspect for damage to the pack and the wiring/connections.

Lithium polymer batteries do not have a hard steel case like a NiMH battery.  Instead, a special aluminium foil encloses them.  Therefore, they do not vent. If the integrity of the battery is compromised, swelling will occur.  If the battery is damaged and the case begins to expand, discontinue use immediately.
