Preflight; Identify Your Model; Charge The Batteries; Balance Propellers - GREAT PLANES Ryan STA Instruction Manual

PREFLIGHT

Identify Your Model

No matter if you fly at an AMA sanctioned R/C club site or if you
fly somewhere on your own, you should always have your
name, address, telephone number and AMA number on or
inside your model. It is required at all AMA R/C club flying sites
and AMA sanctioned flying events. Fill out the identification tag
on page 27 and place it on or inside your model.

Charge the Batteries

Follow the battery charging procedures in your radio
instruction manual. You should always charge your transmitter
and receiver batteries the night before you go flying and at
other times as recommended by the radio manufacturer.
NOTE: Checking the condition of your receiver battery pack
is highly recommended. All battery packs, whether it's a
trusty pack you've just taken out of another model, or a new
battery pack you just purchased, should be cycled, noting
the discharge capacity. Oftentimes a weak battery pack can
be identified (and a valuable model saved!) by comparing its
actual capacity to its rated capacity. Refer to the instructions
and recommendations that come with your cycler. If you
don't own a battery cycler, perhaps you can have a friend
cycle your pack and note the capacity for you.

Balance Propellers

Carefully balance your propellers before you fly. An
unbalanced prop is the single most significant cause of
vibration that can damage your model. Not only will engine
mounting screws and bolts loosen, possibly with disastrous
effect, but vibration may also damage your radio receiver
and battery. Vibration can also cause your fuel to foam,
which will, in turn, cause your engine to run hot or quit.
We use a Top Flite Precision Magnetic Prop Balancer
(TOPQ5700) in the workshop and keep a Great Planes
Fingertip Prop Balancer (GPMQ5000) in our flight box.
Follow the engine manufacturer's instructions to break-
in your engine. After you run the engine on your model,
inspect your model closely to make sure all screws remain
tight and your 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.

ENGINE SAFETY PRECAUTIONS

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 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.
