Balance Propellers
Carefully balance your propeller and spare propellers before
you fl y. An unbalanced prop can be the single most signifi cant
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 fl ight box.
Ground Check & Range Check
Always ground check the operational range of your radio
before the fi rst fl ight of the day following the manufacturer’s
instructions that came with your radio. This should be done
once with the motor off and once with the motor running
at various speeds. 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.
MOTOR SAFETY PRECAUTIONS
Failure to follow these safety precautions may result
in severe injury to yourself and others.
● Get help from an experienced pilot when learning to operate
motors.
● Use safety glasses when starting or running engines.
● Do not run the motor 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 run the motor.
● 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.
AMA SAFETY CODE EXCERPTS
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.
General
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 qualified flier, 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 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.
