WARNING
CONNECTOR CONNECTION
Insert the receiver, servo, and bat-
tery connectors fully and firmly.
If vibration, etc. causes a connector to
work loose during flight, the plane may
crash.
RECEIVER
VIBRATIONPROOFING
/ WATERPROOFING
Vibrationproof the receiver by
wrapping it in sponge rubber or
some such material. If the receiver
may get wet, waterproof it by plac-
ing it in a plastic bag.
If the receiver is subjected to strong vi-
bration and shock, or gets wet, it may op-
erate erroneously and cause a crash.
RECEIVER ANTENNA
Do not cut or bundle the receiver
antenna. Also, do not bundle the
antenna together with the servo
lead wires.
Cutting or bundling the receiver antenna
will lower the receiver sensitivity and
shorten the flight range and cause a
crash.
<Antenna installation>
For aircraft, attach the antenna to the top
of the tail.
Attach the antenna with
a rubber band, etc.
Use a rubber bushing, etc. at the part at
which the antenna comes out of the fuselage
so that it will not break. Also tie a knot in the
antenna wire inside the fuselage so that the
antenna cannot be pulled out.
SERVO THROW
Operate each servo horn over its
full stroke and adjust so that the
pushrod does not bind or is not too
loose.
Unreasonable force applied to the servo
horn will adversely affect the servo and
drain the battery quickly.
SERVO INSTALLATION
Install the servos to the servo
mount, etc. through a rubber
bushing. Also install the servos so
that the servo case does not di-
rectly touch the servo mount or
other parts of the fuselage.
Wood screw
Servo Rubber
Grommet
Servo mount
POWER SWITCH
INSTALLATION
When installing a receiver power switch
to the fuselage, cut a rectangular hole
somewhat larger than the full stroke of
the switch knob and install the switch so it
moves smoothly from ON to OFF.
Also install the switch where it will not
come into direct contact with engine oil,
dust, etc. Generally, install the switch to
the fuselage at the side opposite the muf-
fler exhaust.
