Barley Mow RCCC
GT12, LMP and Tamiya racing in the North East every Sunday
Our main class at Barley Mow.  These are 1/12th scale cars, built to resemble GT racers or touring cars and running to standard BRCA rules.

his class is specifically designed to promote fast, close racing at a moderate cost.  Build and set up are relatively simple, and the cars themselves are readily available, both new and second hand.

Manufacturers include Zen Racing, Schumacher and Mardave

Le Mans Prototype (LMP)
We also race LMP cars.  These are also 1/12th scale, and are considered to be the fastest electric racing class.  LMP cars trace their roots back to the 1970s in the UK and the current cars are lightweight racers built from carbon fibre, aircraft grade alloys and titanium.  

The class is highly competitive, with exacting standards of set up and build.

Manufacturers include Xray, Schumacher, Corally, Associated and Roche

'Mini' race class
The mini class encompasses a number of different types of RC racer.  Primarily based around the Tamiya M05 and Mardave MiniStox chassis, but can also include touring cars.  This class tends to use stock brushed motors and NiMH battery packs to keep costs as low as possible.  

The class is fun, frantic and ideal for entry level racers.

Manufacturers include Tamiya & Mardave.

Whats in a race car?
A typical GT12 car has a number of components - each of which define how the car performs and handles.

The Mardave Venom GT pictured is typical of a current GT12 car raced at Barley Mow (pictures are copyright of Mardave - no copyright claim intended).

Foam tyres in various hardnesses are used in conjunction with softening additives to provide the right amount of grip for your driving style and the track conditions.

GT12 cars tend to have simple spring based independant front suspension and a floating 'pod' type rear suspension.  This is tuneable to suit.  Damper rods are used to control chassis movement.

The ride height of the car is fully adjustable to compensate for tyre wear.

Differential and gearing
Gearing is adjustable for both the axle (spur) gear and the motor (pinion) gear to maximise performance on each track and combination of equipment. GT12 cars use 48dp gears and pinions to get the power down.

A ball differential helps to give sharp handling and turning characteristics.

A brushless 13.5t motor is the club standard. These are commonly available both new and second hand.  Novice racers often benefit from starting with a 17.5t motor as it has a much smoother power delivery.

GT12 racers use a 1S LiPo battery pack, with a nominal voltage of 3.7v.  These range from £20 to £90 each and can be charged many times with a specialist charger.  We recommend a minimum of two packs for a race night.

Speed controller
At the heart of the car, the speed controller converts the radio reciever outputs to control the motor. A typical speed controller for GT12 will have forward and braking only, plus a range of adjustment.  It is preferable to use a controller specifically designed for a 1S LiPo pack, and that has a 'blinky' mode - meaning it is BRCA approved for racing.

Steering servo
At the front of the car, the servo translates the radio reciever outputs to move the wheels and steer the car. Suitable servos range from around £20 to £100.

The reciever is a small unit which understands the commands given over the air by the control unit, or transmitter.  99% of racers now use a digital, 2.4ghz transmitter and reciever, eliminating the need for frequency changes or crystals.

The transponder is a small box that communicates with a timing loop under the carpet. This can be provided by the club at a cost of around £40.

What else is needed?
A number of other items are also needed to get racing, some more critical than others.

A radio transmitter works alongside the reciever unit - changing your inputs of throttle and steering into movement of the car.  Most common is a 'combo' unit - transmitter and reciever together from around £40 to several hundred, depending on features.  Two types are commonly used - sticks and steering wheel.  

Stick sets are the traditional RC handset that most are used to seeing. Steer wheel sets are gun shaped and use a throttle trigger with a side wheel.  Personal preference is how most decide which to use.

99% of racers use a 2.4GHz transmitter and reciever - which needs no frequency changes or interference with other racers.

Charger & charge bag
To safely charge LiPo batteries it is essential to use a dedicated charger designed for charging RC LiPo batteries.  LiPo batteries are safe and reliable when correctly charged and maintained, but can pose a risk if mistreated. Chargers are available from around £25 and are typically powered with a regulated 12v power supply or car battery.

LiPo charge bags are available from RC shops, eBay and Amazon and are mandatory when charging at club.

A selection of simple hand tools is all that is needed to maintain your car. Many can be purchased from normal DIY stores or Amazon. As with any hobby, there are a myriad of specialist tools that can be bought, but its best to start with basics and buy as you need them.

  • Short nose pliers 
  • Wire cutters 
  • Pit towel 
  • 1.5mm & 2mm allen driver 
  • 3mm & 5mm nut spanner 

A soldering iron is also a useful addition, as well as a 'pit box' or hauler to keep your kit in.
