Love Your Batteries

  • Batteries are heavy, expensive and easy to damage. Be careful with them – make sure the handle is connected correctly before lifting. Never drop a battery – this will permanently damage the battery and could seriously hurt your foot!
  • An adult should lift the batteries in and out of the Goblin – at 10kg each they are heavy. Due to their weight it is generally easier to transport the Goblin with the batteries removed.
  • Never store the battery discharged. After any use (training or competition) recharge as soon as possible (i.e. recharge one battery that very same night and then swap the charger to the second battery the following morning).
  • When using the charger make sure both the ‘12V’ and ‘AGM’ lights are lit. Press the ‘Mode’ button to change modes if required.
  • Batteries must be stored in a centrally heated building. Never store in an unheated garage or shed.
  • Never drop or short circuit the battery. Never place a metal object (e.g. spanner) on top of the battery. Do not overtighten the battery connector screw.
  • Make sure you have trickle charged the batteries the day/night before the competition. No charging is allowed (or is required) on competition day – a full battery will easily last all day. Therefore battery chargers are not allowed at the competition venue.

Transport and Storage

  • Most teams arrange for a parent who owns a van or trailer to transport the Goblin car for them on race day. With the roll bar unbolted the Goblin will also fit in most estate cars.
  • To make it easier to lift in and out of the vehicle we recommend the heavy batteries are removed whilst transporting the Goblin.
  • The roll bar can also be fitted to the Goblin horizontally. This then allows the Goblin to be stored on end, with the roll bar acting as a stand.


Tools are not provided with the kit, but only basic hand tools are required. Most schools ask parents to donate surplus tools to the school in order to build up a simple tool kit for the Goblin team. The tools required are below, a suggested tool list can be downloaded here.

  • Set of metric spanners
  • Metric socket set
  • Large and small screwdrivers (flat and posidrive)
  • Ball nose hammer (safer than claw hammers)
  • Set of metric allen keys
  • Bottle of tippex and marker pens
  • Side cutters / scissors / craft knife (for shaping and fixing the bodywork)

Silverline have generously sponsored the Greenpower events for many years, so please consider the Silverline brand when purchasing any new tools!




It is not compulsory to use overalls when building or racing, but many teams do prefer to wear them to protect clothes and provide a ‘team uniform’. The best value overalls are from eBay at around £10 a set – search ‘kids overalls’. Most of these overalls are the BlueCastle brand – size 32 will fit the majority of year 5/6 students.



Driving Practice

  • Wear long trousers, long top and gloves. Covered toe shoes (i.e. trainers not sandals). Long hair tied back and tucked in. Crash helmet on.
  • Get used to the controls. Power button to start, brake to stop. Make sure all drivers know how to switch off power completely in an emergency (via the front rocker switch). Make sure all ‘pushers’ also know how to switch off power completely (via the rear isolator switch).
  • Start by simply pushing the drive around in the vehicle without any power. Let them get used to the steering and brakes. Steer a figure of 8 course around cones and practice stopping in a particular position.
  • When the driver(s) are confident connect one battery only. This provides half power to the Goblin so allows the driver to get used to steering at a slower speed. To do this disconnect wire G2A completely and then connect wires G2B and G2C to the same battery.
  • Do not pulse the power switch on and off rapidly, use the brake to control speed instead. A ‘pusher’ must push start the kart to get it moving (or else a fuse may blow).
  • Practice stopping at a precise place. Do not ‘skid’ to a stop – this just ruins the tyres! Practice slalom course by driving in and out of cones.
  • Remember that events such as the drag can be won/lost by a good/bad push at the start. Practice your starts and remember that in the drag race the job of the ‘pusher’ is probably more important than that of the ‘driver’!
  • Work out a team strategy. Who is the best driver, who is the strongest pusher, who is the best team organiser? Does the driver’s weight/size make a difference (clue: think of horse racing!)?

Is my kit a G2 or G1?

  • For many years the Greenpower competition has been run using G1 ‘tubular’ style goblins. However all new goblins now use the latest second generation G2 ‘pressed steel’ style frames, which are stronger and easier to assemble. The Bath Goblins loan kits are all G2 style.
  • Both G1 and G2 kits use exactly the same batteries, motors, wheels etc. and can therefore compete side by side in any Greenpower Goblin race event.
  • We are aware that a couple of Bath schools may have an old G1 kit hidden away in an old store cupboard! The Bath Goblins team will be delighted to help you refurbish and restore any such kit to bring it back into use.
