Frequently Asked Questions

Radio Control Gas Cars

Can I cut off some of the aerial?

Definitely NOT - the aerial in the vehicle is matched to the aerial in the transmitter, so if you shorten it you will severely shorten the range that you can control the vehicle. If it is too long wrap some around a piece of cardboard and then place it out of harm's way on the chassis.

What is "Range Checking"

Range Checking should be done every time you use any radio control, whether it be for cars, boats, planes, gliders, submarines or helicopters. To Range Check your radio turn it on with the motor running and have someone take the car as far away as you think you are likely to use it. Check that the radio controls all functions correctly at this distance - if not then it is too far away. REMEMBER - when the car goes out of range the servos will stay in the same position - if that means it was going in a straight line at full speed then it will keep on going until the batteries go flat, it runs out of fuel or it hits something!!!!!!

How far can I control it?

Generally the range is around 100 meters - with a couple of important provisos - (1) your batteries are fully charged in both the transmitter and the vehicle (2) your aerial on the transmitter is fully extended and you haven't shortened the receiver aerial (3) there are not a lot of obstructions around such as trees, buildings and rocky outcrops (limestone can greatly reduce the range) (4) do not point the transmitter aerial at the car - the signal is emitted from the sides of the aerial - nothing comes out of the top - think of the signal as "MICKEY MOUSE EARS" (5) Mobile telephones when they are being used - not on standby - can completely destroy the signal being transmitted from your transmitter for a distance of about 30 meters. A fail safe device is now available that can be programmed to stop the car if it gets out of range - cost is only $39.95.

How fast will it go?

This depends on a number of factors: how well you have set up the vehicle in the first place such as the castor and camber of the wheels; what fuel you are using and the type of motor and gearing you have installed - 2 speed gearboxes are available. Speeds of between 30 kph and 100 kph are possible although generally for a stock standard kit, 30- 40kph could be expected.

How long will a tank of fuel last?

This depends on what you are doing with the vehicle. You can expect a 75cc tank to last 10-15 minute.

Should I let the motor cool down before filling up the tank and running again?

It is important to let the motor cool down after use if you want the motor to last. The internals of the motor get extremely hot. High temperatures can lead to premature bearing failure and or high wear in the piston and liner. In very hot weather put the car in the shade and let it cool down.

What happens when the motor wears out?

The motor will lose compression - the seal between the piston and the liner is not complete so the piston cannot compress the air and fuel mixture properly and so the ignition process will not occur and the motor will not start or run properly. The piston and liner can be replaced - the cost for a 15 size motor is usually about $60.00.

What will happen if I run the engine without an air filter?

This is possibly the quickest way to ruin an engine. Running the engine will negate any warranty. It is easy to see if an engine has been run without an air filter because of the score marks on the piston and liner. Dirt entering the engine can ruin the piston and liner in just a few seconds. ALWAYS use an air filter.

Should I grease the drive shafts?

If you want your drive shafts to last then most definitely, YES! A moly grease (black) should be used. All moving parts should be lubricated regularly

Can I use any type of paint for the body?

On hard plastic bodies you may use enamel, lacquer or acrylic paints On poly-carbonate bodies (the see-thru type) you must only use poly-carbonate paint. This is applied on the inside of the body and remains flexible - if you do not use polycarbonate paint then the paint will crack and peel off the first time the body is bent. The protective coating on the outside is then removed to reveal a sparkling painted finish. The body should be washed in warm soapy water and then rinsed and allowed to dry before painting. The decals (stickers) are applied to the outside of the body. A new product is available to remove polycarbonate paint safely from polycarbonate bodies should you need to repaint the body

Why do the servos in the car jitter?

The batteries are flat, you do not have your aerial fully extended or the car is too far away from the transmitter.

What fuel do I use ?

A gas powered vehicle is fueled with a mixture of Methanol and 20% Castor Oil (or synthetic oil). Nitro Methane is used to give the fuel more "punch" and can be added to the fuel. If using "Nitro" then the smoke coming out of the exhaust will sting your eyes. The higher the "Nitro" content then the more "punch" you will get but the engine will wear out quicker. 5% -10% Nitro is most commonly used. The fuel is available pre-mixed or you can mix your own.

What is the Castor Oil for ?

The Castor Oil is used to lubricate the engine - the internals of the engine get to around 200 degrees - the castor oil will not burn at this temperature and all of the oil comes out the exhaust - this is quite normal. The oil can be cleaned off with warm soapy water - do not get it on the radio gear or inside the engine. If the engine has not been used for a while the oil residue will make the engine difficult to turn over - put some fuel down the glow plug hole and turn it over a few times to loosen it up. An after-run oil can be used to stop this problem. Synthetic oils do not have these problems but the engine will not last as long.

Where is reverse gear ?

Gas powered vehicles generally do not have a reverse - only forward and brake. Kyosho do make cars with a reverse called the Dodge Ram Truck and the Field Baja Beetle.

How does the clutch work ?

Gas powered vehicles use a centrifical clutch to connect the engine to the gear box. The clutch engages when the engine?s revs rise. Slow running can lead to burnt clutch shoes - always make sure the engine does not run with the clutch partially engaged.

What maintenance is required ?

General maintenance needs to be done on the chassis - lubricate all moving parts and tighten all nuts and bolts. Make sure the drive gears are always meshing properly. No engine maintenance is generally required other than checking all nuts and bolts.

How does the engine start ?

Most engines use a pull start. The pull starter must only be pulled with small wrist movements - it is not a lawnmower! Connect the glow plug lead to the battery and the glow plug - prime the fuel line, set the throttle half open and pull the starter. We issue a full "GAS BUGGIES" sheet that details this starting procedure. If you would like one or have lost it please ask for one.
