If the engine is new, follow the engine manufacturer’s
instructions to break-in the engine.
After break-in, confirm
that the engine idles reliably, transitions smoothly and rapidly to
full power and maintains full power—indefinitely. After you run
the engine on the model, inspect the model closely to make
sure all screws remained tight, the hinges are secure, the prop
is secure and all pushrods and connectors are secure.
Ground check the operational range of your radio before the
first flight 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 fly!
Find and
correct the problem first. 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.
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 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 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 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 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. 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.
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 safety 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.
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.
