Range Check
Ground check the operational range of your radio before the
fi rst fl ight of the day. With the transmitter antenna collapsed
and the receiver and transmitter on, 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, while
you work the controls, tell you what the control surfaces are
doing. Repeat this test with the engine running at various
speeds with an assistant holding the model, using hand
signals to show you what is happening. If the control surfaces
do not respond correctly, do not fl y! Find and correct the
problem fi rst. Look for loose servo connections or broken
wires, corroded wires on old servo connectors, poor solder
joints in your battery pack or a defective cell, or a damaged
receiver crystal from a previous crash.
ELECTRIC MOTOR & ENGINE
SAFETY PRECAUIONS
The following precautions apply both to electric
motors and gas and glow engines. Failure to follow
these safety precautions may result in severe injury
to yourself and others.
• Keep all engine fuel in a safe place, away from high heat,
sparks or fl ames, as fuel is very fl ammable. Do not smoke
near the engine or fuel; and remember that engine exhaust
gives off a great deal of deadly carbon monoxide. Therefore
do not run the engine in a closed room or garage.
• Get help from an experienced pilot when learning to
operate engines.
• Use safety glasses when starting or running engines.
• Do not run the engine in an area of loose gravel or sand;
the propeller may throw such material in your face or eyes.
• Keep your face and body as well as all spectators away
from the plane of rotation of the propeller as you start and
run the engine.
• Keep these items away from the prop: loose clothing, shirt
sleeves, ties, scarfs, long hair or loose objects such as
pencils or screwdrivers that may fall out of shirt or jacket
pockets into the prop.
• Use a "chicken stick" or electric starter to start the engine.
Do not use your fi ngers to fl ip the propeller. Make certain
the glow plug clip or connector is secure so that it will not
pop off or otherwise get into the running propeller.
• Make all engine adjustments from behind the
rotating propeller.
• The engine gets hot! Do not touch it during or right after
operation. Make sure fuel lines are in good condition so fuel
will not leak onto a hot engine, causing a fi re.
• To stop a glow engine, cut off the fuel supply by closing
off the fuel line or following the engine manufacturer's
recommendations. Do not use hands, fi ngers or any other
body part to try to stop the engine. To stop a gasoline
powered engine an on/off switch should be connected to
the engine coil. Do not throw anything into the propeller of
a running engine.
These precautions apply only to electric-powered models:
• Always remove the LiPo battery from the plane
before charging.
• Always use a charger designed to charge LiPo batteries for
charging the LiPo fl ight battery.
• Never leave the LiPo battery unattended while charging. If
the battery becomes hot, discontinue charging.
AMA SAFETY CODE (
Read and abide by the following excerpts from the Academy
of Model Aeronautics Safety Code. For the complete Safety
Code refer to Model Aviation magazine, the AMA web site or
the Code that came with your AMA license.
1) I will not fl y my model aircraft in sanctioned events, air
shows, or model fl ying demonstrations until it has been
proven to be airworthy by having been previously,
successfully fl ight tested.
2) I will not fl y my model aircraft higher than approximately
400 feet within 3 miles of an airport without notifying the
airport operator. I will give right-of-way and avoid fl ying
in the proximity of full-scale aircraft. Where necessary,
an observer shall be utilized to supervise fl ying to avoid
having models fl y in the proximity of full-scale aircraft.
3) Where established, I will abide by the safety rules for the
fl ying site I use, and I will not willfully and deliberately fl y my
models in a careless, reckless and/or dangerous manner.
5) I will not fl y my model unless it is identifi ed with my name
and address or AMA number, on or in the model. Note:
This does not apply to models while being fl own indoors.
7) I will not operate models with pyrotechnics (any device
that explodes, burns, or propels a projectile of any kind).
Radio Control
1) I will have completed a successful radio equipment ground
check before the fi rst fl ight of a new or repaired model.
2) I will not fl y my model aircraft in the presence of spectators
until I become a qualifi ed fl ier, unless assisted by an
experienced helper.
3) At all fl ying sites a straight or curved line(s) must be
established in front of which all fl ying takes place with the
other side for spectators. Only personnel involved with
fl ying the aircraft are allowed at or in the front of the fl ight
line. Intentional fl ying behind the fl ight line is prohibited.
4) I will operate my model using only radio control frequencies
currently allowed by the Federal Communications Commission.
5) I will not knowingly operate my model within three miles
of any pre-existing fl ying site except in accordance with
the frequency sharing agreement listed [in the complete
AMA Safety Code].
9) Under no circumstances may a pilot or other person touch
a powered model in fl ight; nor should any part of the
model other than the landing gear, intentionally touch
the ground, except while landing.
