While you are installing the battery, receiver, and servos into your
model’s fuselage, please pay attention to the following guidelines:
Wood screw
Rubber grommet
Brass eyelet
Servo mount
or rail
Use the supplied rubber grommets when
you mount each servo. Be sure not to overtighten
the screws. If any portion of the servo case directly
contacts the fuselage or the servo rails, the rubber
grommets will not attenuate vibration, which can
cause mechanical wear and servo failure.
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, any unnecessary load applied to the servo
arm will drain the battery pack quickly.
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 pipe, and pick a location so that 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.
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, and let the excess wire length trail behind. You may run the
antenna inside of a non-metallic housing within the fuselage, but range may suffer if
the antenna is located near metal pushrods or cables. Be sure to perform a range
check before flying.
The receiver contains precision electronic parts. Be sure to avoid vibration,
shock, and temperature extremes.
For protection, wrap the receiver in foam rubber or other vibration-
absorbing materials. It’s also a good idea to waterproof the receiver by placing it
in a plastic bag and securing the open end of the bag with a rubber band before
wrapping it with foam. If you accidentally get moisture inside the receiver, you may
experience intermittent operation or a crash.
