<Before Use>
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 ra-
dio reception sensitivity and range, and may cause a crash.
ƔUse rubber band to stretch
antenna and then fix it.
ƔUse a rubber bushing to the position where
antenna is coming out from the airframe so
that the antenna won't be cut due to the
friction.
ƔUse rubber band to stretch antenna and then
fix it.Make a knot inside of the airframe so that
the antenna will not fall out.

Antenna
Nonmetal tube
*Use rubber grommet or
silicon tube to protect
the antenna from being
cut or from its insula-
tion peeling off at the
fuselage antenna-exit
hole.
*Place the receiver anten-
na out from the fuselage
part to the nonmetal
tube installed in skid
etc. Please keep antenna
away from parts made
of metal and carbon
graphite.

bind or sag when operating the servos to the
full extent.
*If excessive force is continuously applied to a servo, your
aircraft may crash because the servo would be damaged
and the battery would be consumed rapidly.
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 a servo case is contacting directly to the airframe, the
vibration of the airframe directly travels to and may dam-
age the servo.

so that the wire sticks out slightly and fasten it at
suitable points. In addition, periodically check the
wire 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
