g. How to change frequencies
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.
Receiver
Plug in an interchangeable crystal into the receiver for a rapid
change of frequencies.

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. One, purchase a
temperature gauge. 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 den-
sity, and humidity, your carburettor settings will be changing
wherever you decide to run. Making adjustments in small incre-
ments 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. 3,5 ccm engines are designed to last a long time,
and with proper maintance 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 normal idle, preferable 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 over-
heat! 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 pull the
pull-start a few times 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 paintbrush, or
compressed air. Always test the transmitter and receiver batte-
ries before starting the engine.
Racer Tip:
Wear gloves when working on your hot car!
