It is very important to display your transmitters channel number
at
all times. To install your frequency flag device on your
transmitters
antenna, slide the appropriate paper numbers into
the
slots and slip the device onto the transmitters antenna.
Radio Installation Notes
While you are installing the battery, receiver, and servos into
your
model's fuselage, please pay attention to the following
guidelines:
Notes on Servos
Mounting
When you mount each servo, use the supplied rubber
grommets
and insert an eyelet up through the bottom. Be sure
not
to over tighten the screws. If any portion of the servo case
directly
contacts the fuselage or the servo rails, the rubber
grommets
will not be able to attenuate vibration, which can
lead
to mechanical wear and servo failure.
Switch Harness Installation
When you are ready to install the switch harness, remove the
switch
cover and use it as a template to cut screw holes and a
rectangular
hole slightly larger than the full stroke of the switch.
Choose
a switch location on the opposite side of the fuselage
from
the engine exhaust, and choose a location where it can't
be
inadvertently turned on or off during handling or storage.
Install
the switch so that it moves without restriction and "snaps"
from
ON to OFF and vice versa.
Receiver Notes
DO NOT cut or coil the receiver antenna wire. It is normal for
the
receiver antenna to be longer than the fuselage. DO NOT
cut
it or fold it back on itself - cutting or folding changes the
electrical
length of the antenna and may reduce range.
Secure the antenna to the top of the vertical fin or the tail boom,
and
let the excess length trail behind the aircraft (be sure it
cannot
tangle with the tail rotor on a helicopter).
Servo Throw
Once you have installed the servos, operate each one over its
full
travel and check that the pushrod and output arms do not
bind
or collide with each other, even at extreme trim settings.
Check
to see that each control linkage does not require undue
force
to move (if you hear a servo buzzing when there is no
transmitter
control motion, most likely there is too much friction
in
the control or pushrod). Even though the servo will tolerate
loads
like this, they will drain the battery pack much more rapidly.
You may run the antenna inside of a non-metallic housing
within
the fuselage (a plastic outer pushrod housing works well
for
this), but range may suffer if the antenna is located near
metal
pushrods or cables. Be sure to perform a range check
before
flying. With the antenna collapsed, you should be able
to
walk 20 - 30 paces from the model without losing control or
seeing
"jitter" in the servos. The range check should be done
with
the motor running and the model should be securely
restrained
in case of loss of control.
