Balance the Model Laterally

❏

1. With the wing level, have an assistant help you lift the

model by the motor propeller shaft and the bottom of the

fuse under the TE of the fin. Do this several times.

❏

2. If one wing always drops when you lift the model, it means

that side is heavy. Balance the airplane by adding weight to the

other wing tip. An airplane that has been laterally balanced

will track better in loops and other maneuvers.

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.

Charge the Batteries

Follow the battery charging instructions that came with your

radio control system to charge the batteries. You should

always charge your transmitter and airplane batteries the

night before you go flying, and at other times as

recommended by the radio manufacturer.

CAUTION: Unless the instructions that came with your

radio system state differently, the initial charge on new

transmitter and receiver batteries should be done for 15

hours using the slow-charger that came with the radio

system. This will "condition" the batteries so that the next

charge may be done using the fast-charger of your

choice. If the initial charge is done with a fast-charger the

batteries may not reach their full capacity and you may be

flying with batteries that are only partially charged.

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. Vibration may

also damage your radio receiver and battery. We use a Top

Flite Precision Magnetic Prop Balancer

workshop and keep a Great Planes Fingertip Prop Balancer

(GPMQ5000) in our flight box.

Keep your face and body as well as all spectators away from

the plane of rotation of the propeller whenever the battery

is connected.

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.

Range Check

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 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 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.

AMA SAFETY CODE (

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).
