Safety Precautions When Installing Servos - FUTABA T18SZ Instruction Manual

Mounting the Servo
Wood screw
Rubber
grommet
Brass eyelet
Servo mount
(Airplane/Glider)
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.
Margin in the lead wire.
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.

＜ Before Use ＞
2.3-2.6mm nut
washer
Rubber
grommet
Brass eyelet
Servo mount
2.3-2.6mm screw
(Helicopter)
Fasten about 5-10cm
from the servo outlet so
that the lead wire is neat
secure.
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 ser-
vo, 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.
