ANSWER:

In the first instance we would suggest watching the DVD included with your car again and restarting the setup procedure, just to make sure you have not missed anything. You can also find a tutorial video on HPI.TV

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. You should find these on the DVD or in the instruction manual provided with your car. 

If this fails to resolve your issue then you can contact either your local model shop or the After Sales Care line (0845 00 66 160) for further help and advice.

ANSWER:

There are one of two possible problems:

1) The glowplug may require replacement. You can find details of the glowplugs that HPI have available on the website.

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

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.

ANSWER:

I'm sorry but HPI does not offer any exchanges on this basis. Some model shops may offer a trade-in, but in practise most will not. Why not sell the car privately to a friend to help finance your next dream RC car?

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.

If you have an HPI Savage you can also use the optional Engine Stop System with your car - this is compatible with all of the Savage series except the XL.

ANSWER:

Your car is supplied with a comprehensive instruction manual and in some cases a DVD too. We recommend that you follow the guidelines given to help ensure that your engine has the best possible mix of  life and performance.

If you need a copy of the instuctions for your car then you can download them from the HPI Europe website!

You can also find helpful 'Getting Started' videos in the Learning Lab on HPI.TV if you require further assistance.

ANSWER:

A slipper clutch is a device that fits on or near the spur gear, and helps absorb "drivetrain shock" that occurs when a car lands from a jump. A slipper clutch also helps aid traction in slippery conditions, since it acts as a mechanical way to limit the power that reaches the drivetrain.

ANSWER:

The runtime for a tank of fuel can vary depending on the conditions that the car is being used in, but it will typically be between 10 and 15 minutes per tank on most nitro cars. Don't forget that you can refuel with the engine still running so you can enjoy the car for longer periods without stopping!

When your car is new and the engine is still tight and set very rich it's normal for the car to use more fuel, but once the break in process is complete then this will improve.

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.

ANSWER:

We are a trade only distributor, so unfortunately you will not be able to purchase parts directly from us.

You can use the shop finder facility here to find a local stockist who will be able to supply you with the parts that you need. In the event that the shop does not have the part in stock then they should be able to order it for you - If the parts you need are in stock at HPI then they should be available to them within 2-3 days!

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, have easy tuning characteristics and provide 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.

For the petrol powered cars that we offer you should use unleaded fuel mixed with a good quality two stroke oil at a 25:1 ratio.

ANSWER:

The One Way Bearing is normally very reliable and will only fail in the event that it's over-loaded. This is normally caused by attempting to start the engine whilst it's flooded.

If the Rotostart jams or the Pullstart becomes difficult to pull then you can remove the glowplug and clear the engine as shown on the DVD included with HPI kits. The engine should then be easier to turn over.

If you follow the above steps then your One Way Bearing will thank you!
