Servo Installation Notes
Mounting
Servo Throw
Factory Repair Service Information
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.
Please read the warranty card supplied with your system and
return it. Before you decide to have your system repaired, if
there is no apparent physical damage, read this instruction
manual again and check to be sure that you are operating the
system as it was designed to be operated. If you are still having
trouble, pack up your system in its original shipping materials
and send it to the nearest authorized Hitec R/C Service Center.
Be sure to include a note in your package that describes the
trouble in as much detail as possible, including:
" Symptoms of the problem in as much detail as you can
provide, including any unusual mounting conditions or
equipment orientation
" A list of items you are sending, and what you want to be
repaired.
" Your name, address, and telephone number.
Glossary
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

Using Servo Wire Extensions
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.
Connectors
Be sure the alignment of a servo or battery connector is correct
before inserting it into the receiver. To remove a connector from
the receiver, try to pull on the connector's plastic housing rather
than pulling on the wires. Pulling the wires can ruin the
connector pins and break wires.
If any of your servos are located too far away to plug directly
into the receiver (like the aileron servo), or you need to unplug
the servo each time you disassemble the model, use a servo
extension cord to extend the length of the servo lead.
Additional Hitec extension cords of varying lengths are available
from your hobby dealer.
Radio Installation Notes
Vibration and Waterproofing
Switch Harness Installation
Antenna
The receiver contains precision electronic parts. Be sure to
avoid vibration, shock, and temperature extremes.
For protection, wrap the receiver in the provided "Flight
Preserver" foam rubber, or use some other vibration-absorbing
materials. If your flying near bodies of water, 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.
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.
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).
When you are ready to install the receiver's switch harness,
remove the switch cover and use it as a template to cut screw
