hands) after each flight. Store fuel soaked rubber
bands in a container with talcum powder or corn
starch to absorb the oil. Get help from an experienced pilot when you learn
to operate engines.
Use safety glasses when you operate model engines.
RANGE CHECK THE RADIO
Check the operational range of the radio before the
first flight. Before you turn your radio on the first
thing you always must do is make sure no one else
is on your frequency (channel). Most model flying
fields utilize frequency control so familiarize yourself
with their system. Collapse your transmitter antenna
and turn on the transmitter, then the receiver
(preferably the receiver should never be on by itself).
You should be able to walk at least 100 feet away
from the model and still have control. Have an
assistant stand by your model and tell you what the
control surfaces are doing while you operate them
from the transmitter.
Repeat this test with an assistant holding the model
and the engine running at various speeds. If the
control surfaces do not always respond correctly,
don't fly! Find and correct the problem first. Look for
loose servo connections or corrosion, loose fasteners
that may cause vibration, a defective on/off switch,
low battery voltage or a defective cell, a damaged
receiver antenna, or a receiver crystal that may have
been damaged from a previous crash.
NOTE: Failure to follow these safety precautions
may cause severe injury to yourself and others.
Store model fuel in a safe place away from high
heat, sparks or flames. Do not smoke near the
engine or fuel as it is very flammable. Engine
exhaust gives off a great deal of deadly carbon
monoxide so do not run the engine in a closed
room or garage.
Do not run the engine near loose gravel or sand; the
propeller may throw loose material in your face
or eyes.
When you start and run the engine, keep your face
and body as well as all spectators away from the
plane of rotation of the propeller.
Keep loose clothing, shirt sleeves, ties, scarfs, long
hair or loose objects away from the prop. Be
conscious of pencils, screwdrivers or other objects
that may fall out of your shirt or jacket pockets.
Use a "chicken stick" or spring starter and follow the
instructions to start your engine.
Make certain the glow plug clip is secure so that it
will not pop off or get into the running propeller.
Ask an assistant to hold the model from the rear
while you start the engine and operate the controls.
Make all engine adjustments from behind the
rotating propeller.
The engine gets hot! Do not touch the engine during
operation or immediately after you operate it.
To stop the engine, close the carburetor barrel (rotor)
or pinch the fuel line to discontinue the fuel flow. Do
not use your hands, fingers or any body part to stop
the propeller.
Never throw anything into the prop of a running engine.
