Engine Safety Precautions; Ama Safety Code (Excerpt); General; Radio Control - GREAT PLANES Piper J-3 Cub Instruction Manual

Repeat this test with the engine running at various speeds
with a helper holding the model. If the control surfaces are
not always responding correctly, do not fly! Find and correct
the problem first. Look for loose servo connections or
corrosion, loose bolts that may cause vibration, a defective
on/off switch, low battery voltage or a defective receiver
battery, a damaged receiver antenna, or a receiver crystal
that may have been damaged from a previous crash.

Engine Safety Precautions

Note: 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 flames, as fuel is very flammable. Do not smoke
near the engine or fuel; and remember that the engine
exhaust gives off a great deal of deadly carbon monoxide.
Do not run the engine in a closed room or garage.
Get help from an experienced pilot when learning to operate
gas 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 fingers to flip 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 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 fire.
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, fingers or any other
body part to try to stop the engine. Do not throw anything
into the propeller of a running engine.
AMA SAFETY CODE (excerpts)
Read and abide by the following Academy of Model
Aeronautics Official Safety Code:

GENERAL

1. I will not fly my model aircraft in sanctioned events, air
shows, or model flying demonstrations until it has been
proven to be airworthy by having been previously
successfully flight tested.
2. I will not fly 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 to and avoid flying in
the proximity of full-scale aircraft. Where necessary an
observer shall be used to supervise flying to avoid having
models fly in the proximity of full-scale aircraft.
3. Where established, I will abide by the safely rules for the
flying site I use and I will not willfully and deliberately fly my
models in a careless, reckless and/or dangerous manner.
7. I will not fly my model unless it is identified with my name
and address or AMA number, on or in the model.
9. 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 first flight of a new or repaired
model airplane.
2. I will not fly my model aircraft in the presence of
spectators until I become a qualified flier, unless assisted by
an experienced helper.
3. I will perform my initial turn after takeoff away from the pit
or spectator areas and I will not thereafter fly over pit or
spectator areas, unless beyond my control.
4. I will operate my model using only radio control
frequencies currently
