INSTALLATION AND ADJUSTMENT
WARNING
Connector Connection
Insert the receiver, servo, and
battery 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 re-
ceiver may get wet, waterproof
it by placing it in a plastic bag.
If the receiver is subjected to strong vibra-
tion and shock, or gets wet, it may operate
erroneously and cause a crash.
Receiver Antenna
Do not cut or bundle the re-
ceiver 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.
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
grommet. Also install the servos
so that the servo case does not
directly touch the servo mount
or other parts of the fuselage.
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 muffler exhaust.
