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 included

identification tag on page 29 and place it on or inside your

model.

Balance Propellers

Carefully balance your propeller and spare propellers before

you fly. An unbalanced prop can be the single most significant

cause of vibration that can damage your model. Not only

will motor mounting screws loosen, possibly with disastrous

effect, but vibration may also damage your radio gear.

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.

Range Check

When you get to your flying site ground check the operational

range of the radio before the first flight of the day. With the

transmitter antenna collapsed or the transmitter in “power

down” mode 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 motor 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 or battery connections,

damaged wires or a damaged receiver crystal from a previous

crash in another model. One other possible source of radio

“noise” that could cause interference is the arrangement and

relative location of the receiver, receiver antenna and motor

wires. If possible, remount the receiver in a different location

or reroute some of the wires. Then try the range check again.

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 electric motors.

• Use safety glasses when operating motors.

• Do not operate 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 operate

the motor.

• Keep these items away from the prop: loose clothing, shirt

sleeves, sweater strings, ties, scarves, long hair or loose

objects such as pencils or screwdrivers that may fall out of

shirt or jacket pockets into the prop.

• Always keep your radio on when plugging the motor

batteries into the ESC.

• Stay clear of the propeller at all times: Some ESC units do

not have safety arming features, so any movement of the

throttle stick may cause the propeller to turn.

• Always use a charger designed to charge LiPo batteries for

charging the LiPo flight battery.

• Never leave the LiPo battery unattended while charging. If

the battery becomes hot, discontinue charging.

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 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 and avoid flying in the

proximity of full-scale aircraft. Where necessary, an observer

shall be utilized 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.

5) I will not fly my model unless it is identified with my name

and address or AMA number, on or in the model. Note: This

does not apply to models while being flown indoors.

7) I will not operate models with pyrotechnics (any device

that explodes, burns, or propels a projectile of any kind).
