(Academy of Model Aeronautics) chartered club field.

Ask your hobby shop dealer if there is such a club in your

area and join. Club fields are set up for R/C flying which

makes your outing safer and more enjoyable. The AMA

can also tell you the name of a club in your area. We

recommend that you join AMA and a local club so you

can have a safe place to fly and also have insurance to

cover you in case of a flying accident. (The AMA address

is listed on the front cover of this instruction book).

If a club and its flying site are not available, you

need to find a large, grassy area at least 6 miles away from

any other R/C radio operation like R/C boats and R/C

cars and away from houses, buildings and streets. A

schoolyard may look inviting but it is too close to people,

power

lines and possible radio interference.

GROUND CHECK THE MODEL

If you are not thoroughly familiar with the operation

of R/C models, ask an experienced modeler to check to

see that you have the radio installed correctly and that all

the control surfaces do what they are supposed to. The

engine operation must also be checked and the engine

"broken in" on the ground by running the engine for at

least two tanks of fuel. Follow the engine manufac-

turer's recommendations for break-in. Check to

make sure all screws remain tight, that the hinges are

secure and that the prop is on tight.

RANGE CHECK YOUR RADIO

Wherever you do fly, you need to check the

operation of the radio before every time you fly. This

means 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 someone help you. Have them stand by

your model and, while you work the controls, tell you

what the various control surfaces are doing.

Repeat this test with the engine running at

various speeds with an assistant holding the model. If

the control surfaces are not acting correctly at all times,

do not fly! Find and correct the problem first.

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; remember that the 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 learn-

ing to operate engines.

Use safety glasses when starting or running

engines.

not run the engine in an area of loose gravel

or sand; as 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 items such as these away from the prop:

loose clothing, shirt sleeves, ties, scarfs, long hair or

loose objects (pencils, screw drivers) that may fall out of

shirt or jacket pockets into the prop.

Use a " chicken stick'' device or electric starter,

follow instructions supplied with the starter or stick.

Make certain the glow plug clip or connector is secure

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

after operation. Make sure fuel lines are in good condi-

tion so fuel is not leaked onto a hot engine causing a fire.

To stop the engine, cut off the fuel supply by

closing off the fuel line or follow the engine manufac-

turer's recommendations. Do not use hands, fingers or

any body part to try to stop the engine. Do not throw

anything into the prop of a running engine.
