G racing IMPORTANT FAQ’S & GLOSSARY will provide answers to frequently asked questions about G-racing vehicles, parts and the RC hobby.


 1. How Fast Do They Go?

Answer: The top speed of your car will vary according to a wide range of factors, including the fuel used and the conditions that the car is run in. RC cars can speed upto 50 – 100 kilometer  per hour


2. My Car Will Not Start, What Can I Do ?

In the first instance we would suggest reading the manual of the car, and then  restarting the setup procedure, just     to make sure you have not missed anything.

Once you have checked you are following the correct starting procedure then you should ensure that your car's         engine is set to it's factory base settings.

If this fails to resolve your issue then you can contact us for further help.


3. My Engine Stalls When I Remove The Glow Starter

ANSWER: There is one of two possible problems:

1) The glow plug may be faulty and require replacement. You can find details of the glow plugs that we sell .

2) Your engine may be set too rich - try returning the engine to it\'s base settings as shown in the instruction manual and beginning the tuning process again.


 4.  My Nitro Car Stalls When I Apply The Brake

ANSWER:It sounds like your idle speed is set too low. Try turning the idle screw 1/2 turn clockwise and start the engine of your car with the wheels off the ground. You can use your instruction manual to help identify the idle screw if you are unsure where to find it.

Next, apply the brakes on your transmitter and start turning the idle screw slowly anti-clockwise until the engine stalls. Once you have reached this point, turn the idle screw 1/8 turn clockwise again.

When set correctly the car should sit at a standstill when the engine is idling. You may find that on a brand new car the idle has to be set slightly higher so that the car does not stall. This is acceptable provided the car is not moving quicker than walking pace. You should be able to reduce the idle speed after a few more tanks of fuel.


 5.What's The Best Way To Stop A Nitro Engine ?

ANSWER:There are several methods of stopping your engine; the easiest is to use a rag pressed over the tip of your engine's exhaust. Be very careful when doing this, the exhaust on your car is likely to be hot, especially if it is made of metal!

You can also pinch the fuel line running from the fuel tank to the engine until the engine stalls. It is recommended that you do this with the car's wheels off the floor; as the fuel runs out the engine revs will increase before the engine stalls.


 6. What Is, And How Do I Use After Run Oil?

ANSWER:Nitro engine fuel can absorb moisture and of course moisture is destructive to the inside of a nitro engine. Coating the internal engine parts in after run oil keeps out moisture and keeps the engine’s components in the best possible condition.

To apply after run oil first remove the glow plug. All that is needed is a few drops of after run oil into the glow plug hole in the top of the engine and a few drops into the air intake of the carburettor. Turn the engine over a few times by hand and replace the glow plug. If the engine is to be left for some time then it is worth making sure that the exhaust and air intake holes are blocked to keep out moisture and dirt.


 7.What Fuel Should I Use?

ANSWER:The type of fuel that you require will depend on the engine that is fitted into your car - we would suggest either 16% Nitro or 20% Nitro fuels for small block (.12-.18) engines and 20% Nitro or 25% Nitro fuels for big block (.21-.36) engines.

We always run our cars on the fuels that we distribute and find them to run reliably with a long engine life so we wouldn't hesitate to recommend that you also use them in your car. Your local model shop will also be happy to advise on other fuels that they have available that suit your requirements.


 8. What Is A Glow Plug Igniter?

ANSWER:A glow plug igniter is a battery-powered spring-loaded tube that fits over the glow plug of an engine to heat up the glow plug until it is red-hot (usually 2-3 seconds is all it takes). With fuel in the carburetor, the pull starter is pulled or the starter box engages the flywheel. If the engine is tuned properly, it will start right up. Every R/C engine needs a glow plug igniter to start

Ø        6-Cell Battery: The most common configuration of surface RC batteries, a 6-cell battery pack is constructed out of 6 individual cells that are soldered or spot welded together. The output voltage of a 6-cell battery is rated at 7.2 volts. A 6-cell battery pack is commonly referred to as a "Stick Pack".


Ø        Anti-Squat: The angle of the rear inboard suspension mounts when they are angled towards the rear of the chassis.

Ø        Backplate: A plate that seals off the rear of the crankcase of an engine. Backplates can be designed to accommodate pull start mechanisms as well.


Ø        Battery Cycling: To fully discharge and charge a battery in order to erase battery memory.
