Servo lead wires

To prevent the servo lead cable from being

broken by vibration during flight, provide a

little slack in the cable and fasten it at suitable

points. Periodically check the cable during daily

maintenance.

Fasten about 5-10cm
from the servo outlet so
that the lead wire is neat.

MOUNTING THE POWER

SWITCH

When mounting a power switch to an airframe,

make a rectangular hole that is a little larger than

the total stroke of the switch so that you can turn

the switch ON/OFF without binding.

Avoid mounting the switch where it can be

covered by engine oil and dust. In general, it is

recommended to mount the power switch on the

side of the fuselage that is opposite the muffler.

SAFETY PRECAUTIONS

when

you install receiver and servos

Warning

Connecting connectors

Be sure to insert the connector until it

stops at the deepest point.

How to protect the receiver from

vibration and water

Wrap the receiver with something soft

such as foam rubber to avoid vibration.

If there is a chance of getting wet, put

the receiver in a waterproof bag or

balloon to avoid water.

Receiver's antenna

Never cut the receiver's antenna. Do

not bind the receiver's antenna with the

cables for servos.

Locate the receiver's antenna as far as

possible from metals or carbon fiber

components such as frames, cables, etc.

*Cutting or binding the receiver's antenna will

reduce the radio reception sensitivity and range,

and may cause a crash.

Servo throw

Adjust your system so that pushrods

will not bind or sag when operating the

servos to the full extent.

*If excessive force is continuously applied to a

servo, the servo could be damaged due to force

on the gear train and/or power consumption

causing rapid battery drain.

Mounting servos

Use a vibration-proof rubber (such as

rubber grommet) under a servo when

mounting the servo on a servo mount.

And be sure that the servo cases do not

touch directly to the metal parts such as

servo mount.

*If the servo case contacts the airframe directly,

vibration will travel to and possibly damage the

servo.
