Balance the Model Laterally

❏

1. With the wing level, lift the model by the prop shaft

and the bottom of the fuse under the TE of the fuse. 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 ﬂ y at an AMA sanctioned R/C club site or

if you ﬂ y 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

ﬂ ying sites and AMA sanctioned ﬂ ying events. Fill out the

identiﬁ cation tag on the back cover page of this manual and

place it on or inside your model.

Charge the Transmitter Batteries

Follow the battery charging instructions that came with your

radio control system to charge the transmitter. You should always

charge your transmitter the night before you go ﬂ ying, 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 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 ﬂ ying with

batteries that are only partially charged.

Balance the 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 motor mounting screws and bolts loosen, possibly with

disastrous effect, but vibration may also damage your radio

receiver and servos.

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.

Proper Care of Your Motor

Using multiple battery packs to run the motor for successive

ﬂ ights may cause the motor to become excessively hot. We

recommend at least a 10-minute motor cool-down period

between ﬂ ights.

Before the ﬁ rst ﬂ ight, inspect the model closely to make sure

all screws remained tight, the hinges are secure, the prop is

secure and all pushrods and connectors are secure.

Ground check the operational range of your radio before the

ﬁ rst ﬂ ight of the day. With the transmitter antenna collapsed

and the receiver and transmitter on, you should be able to

walk at least 30m [100'] 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 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 & BATTERY SAFETY PRECAUTIONS

Failure to follow these safety precautions may result

in severe injury to yourself and others.

Use safety glasses when running the motor.

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.

Always remove the LiPo (Lithium-Polymer) battery from the

plane before charging.

™

Always use a charger designed to charge LiPo batteries for

charging the LiPo ﬂ ight battery.
