g. How to Change Frequencies
GB
Transmitter
A rapid change of frequencies is possible simply by
unplugging an interchangeable plug in crystal on the back of
the transmitter and then
plugging in another one
of a different frequency.
Crystals for both the
transmitter and receiver
must be matched with
each other.
Make sure that the
crystal is fully inserted
in the transmitter and
receiver, not partially.
h. Care and Maintenance
Failure to follow break-in procedure and/or damage caused by
improper tuning will void your engine warranty.
There are two ways to "temp" your engine. We recommend
buying an infrared thermometer. The second cheaper, but less
accurate method is the "Spit Test". Wipe a little bit of saliva on
the engine head and it should burn off in 3 - 4 seconds. If it
evaporates immediately, chances are the engine is running too
hot.
The engine will run best and be easier to restart if run around
100-125 °C. Depending on your weather conditions, air density,
and humidity, your carburettor settings will be changing
wherever you decide to run. Making adjustments in small
increments is the best way to make sure your engine lasts a
long time. Overheating is caused by running the engine too
lean, or too much stress on the engine created by the
environment. Extreme overheating will result in internal failure
of engine parts.
There are many online resources that will help you with engine
tuning. Our engines are designed to last a long time, and with
proper maintenance and tuning, you can drive the model for
hours at a time.
After Use
When you have finished running your car, there are two options
to shut the engine down. The first method is to place your
thumb over the exhaust outlet (Wear gloves). Make sure your
engine is preferably normal idle, with the brake activated.
The second method is to pinch off the air supply from the
engine. Do not pinch the fuel line, as this may cause the engine
to overheat!
Try and let all the remaining fuel run through the engine,
emptying the fuel tank. The engine will idle high while the tank
is emptied, so the above two steps may not be necessary.

Then apply after-run oil through the carburettor, and use the
starter for 2 - 3 seconds to get it through the engine. This is
recommended if you plan on storing the car for more than a
day. Methanol evaporates in water and can cause internal
corrosion to engine parts. It is always a good idea to check
all the screws, nuts, and bolts before and after each period of
racing.

Keeping the car clean will also make it more fun to work on.
This can be achieved with a large heavy-duty brush or a
paintbrush. Always test the transmitter and receiver batteries
before starting the engine.
Racer Tip:
Wear gloves when working on your hot car!
