BATTERY CHARGER
The pilot lamps on the battery charger should always be on during the
charging operation. If they are not, check to make sure you have
turned off both the transmitter and receiver.
Do not use the charger for equipment other than this system. The
charging plug polarity may not be the same and equipment damage
may result. Do not use other manufacturers’ after-market accessories
that plug into the transmitter’s charging jack. If you do, any damage
that results will not be covered by the warranty. If you are unsure of
compatibilities with your radio, seek expert advice before doing any-
thing to avoid possible damage. During the charging operation, the
charger’s temperature is slightly elevated. This is normal.
Special note on EXPERT transmitter charge polarity:
7. CHARGING YOUR EXPERT RADIO SYSTEM PRIOR TO INSTALLATION
Your EXPERT Radio System is shipped from the factory with both the
transmitter and receiver NiCad batteries in a discharged state. Before
attempting to install/operate your EXPERT system, it is important that
the system be charged for approximately 24 hours to ensure that both
transmitter and receiver packs are at peak capacity.
Under normal conditions, subsequent recharging of your EXPERT system
will require only an overnight charge (approximately 16 hours) to
attainpeakchargecapacity.
The charger supplied with this system is designed to recharge your
transmitter and receiver battery packs at a rate of 50mAh.
The center pin of the charge receptacle on this radio system is Negative
polarity. Therefore, the center pin is negative, not positive. Your radio
system’s charge polarity is reversed from many other manufacturers
chargers. Beware of improper polarity connections based on “color
code” wire leads as they DO NOT APPLY in this instance.
You must always be certain that the center pin on any charger used
with this system is wired for negative polarity, otherwise damage will
occur to the charge circuit of the EXPERT. The Expert warranty does not
cover any system that is damaged by reverse polarity charging.

SYSTEM CHECK
Slide the power on/off switch on your EXPERT Transmitter to the
“on”position.
Next, slide the on/off switch on your flight pack switch harness to the
“on”position.
By moving each of the two transmitter sticks in a fore-aft, left-right
motion,thecorresponding throttle, rudder, elevator, and aileron
(optional) servo arm/wheel will rotate. Please refer to the transmitter
stickfunctionchartbelowforclarification.
With the system still activated (on), move the throttle stick to the
neutral (center) position. Double check to be sure that the four
transmitter trim levers are still in their neutral position.
Next, with the power still activated to the transmitter and flight pack,
remove the servo arm/horn from each of the SL500 servos, and then
turn the power “off” to the flight pack first, then the transmitter. By
doing this, the SL500 servos will be left in their neutral position, and
they are now ready to be installed into your model.
NOTE: Save the servo arms/horns; they will be reattached to the
servosafterinstallation.

INSTALLATION SUGGESTIONS
Flight pack installation varies greatly from one model to another. For
your convenience, we have included the photograph below outlining a typical flight pack installation in a standard 4-channel trainer type modelairplane.
Itisimportanttocorrectly install the radio system in your model.
Please read and carefully follow the suggestions listed below:
1. For added protection, wrap the receiver and the receiver NiCad in
foam rubber that is at least 1/4" thick.
2. Run the receiver antenna through the fuselage and make sure it is
fully extended. Never cut or bundle your receiver antenna —
thiswilldecreaserangeandperformance.
3. Rubber servo grommets are included with your radio system and
should be installed in the servo flanges. The servos should then be
mounted on either hardwood rails or a plywood tray with the
mounting screws provided. Do not overtighten the mounting screws.
The flange of the brass eyelets should face down (toward the
wood).SeeSection9.3.
4. With the servo at neutral, install the required servo arm/horn
exactly 90 degrees to the servo case as shown in the diagram
below.
5. Before installing the servo output arms, make sure the servo is in
itsneutralposition.
6. All servos must be able to move freely over the full range of their
travel. Make sure the linkages do not impede servo travel. A stalled
servo will drain the battery pack within a few minutes.
7. In the case of gas-powered model aircraft, mount the receiver
power switch on the side of the fuselage opposite the muffler to
protect the switch from exhaust residue. With other types of models,
mount the switch in the most convenient place. Make sure the
switch operates freely and is capable of traveling its full distance.

SERVO REVERSING/SETTING REVERSING SWITCHES
After radio installation, it is imperative that the proper servo/control
system direction be established. Servo reversing allows you to alter the
direction of the servo/control surface movement to match the direction
of the transmitter stick. Please refer to the chart in the following section
below to determine the proper control surface direction.
1. Connect all control linkages and check to see that all servos
movefreely.
2. While standing directly behind the airplane, go through the steps
shown in the charts below to check proper direction of the
controlsurface.
3. Using the Servo Reversing Switches located on the front of the
transmitter, adjust the direction of each servo as necessary for
properoperation.

EXPERT Manual
The final step in your flight pack installation will be to determine the
amount each control surface will move on your model at full transmit-
ter stick deflection. Please refer to your aircraft’s instruction manual
forsuggestedtravellimits.
It is possible to increase/decrease the amount that your control surface
moves at full stick deflection by mechanical adjustments.
It is imperative that the servo does not attempt to push/pull the con-
trol surface past its mechanical limits. This condition is called “binding.”
When a servo moves a control surface into a “binding” position, the
servo itself then becomes “stalled,” unable to reach its full deflection.
This condition is both harmful to your control linkage and to your
servo. This “stalled” condition will also force the servo to drain power
morequicklyfromyourflightpackbattery, thereby reducing your
usable flying time. Fortunately, servo “stalling” is usually easy to
detect by either a “buzzing” or “humming” sound which comes from
thestalledservo.
The following diagram is designed to help clarify how to increase or
decrease control surface travel mechanically to eliminate control sur-
face“binding”andservo“stalling”.
To increase control surface travel, select a linkage attachment point fur-
ther outward on the servo arm or further inward on the control horn
closer to the control surface (Figure 2).
To reduce control surface travel, select the linkage attachment point
close to the center of the servo area or further out on the control horn
on the control surface (Figure 3).
Quite simply, by moving the control rod in on the servo arm/wheel,
control surface travel will be reduced, and by moving the control rod
out on the servo arm, the control surface travel will be increased. The
opposite holds true for the control surface arm (horn) as well. You may
also use any combination of these positions to achieve proper control
surface/servotravel.
NOTE:Once the appropriate servo arm/wheel and control rod location
has been established, be certain that you have secured the
servo arm to the servo output shaft using the original servo
hornscrew.

EXPERT TRAINER SYSTEM
The EXPERT features a built-in trainer system. The transmitter can be
used as either a master (trainer) or as a slave (trainee). The EXPERT is
compatiblewithallothercurrent PPM selectable (FM) EXPERT or JR
radios that have built-in trainer systems. An optional trainer cord is
needed(EXRA400).
OPERATING THE TRAINER SYSTEM
1. Match the servo reversing and trims of both radios.
2. Plug the optional trainer cord into both transmitters.
3. Turnonthemastertransmitter.
NOTE: The slave radio must be left off.
4. Test all the control functions on your aircraft with the master radio.
5. Push the trainer button on the master transmitter and check all the
control functions with the slave radio.
Special Note to Beginners: We strongly suggest that you seek the
help of an experienced model airplane
pilot prior to flying your new model.
RANGE TESTING YOUR MODEL
We suggest that before the initial flight of your model, you first
perform a ground range test to ensure that the transmitting/receiving
abilities of your EXPERT perform properly. Conduct the range test
asfollows:
Do not extend the transmitter antenna at this time. Turn your EXPERT
transmitter “on.” Next, turn the model switch “on.” Slowly walk away
from the model while moving the control surfaces. The system should
function properly to a distance of approximately 60-65 feet.
NOTE: If your test falls short of the described range, confirm that your
NiCad batteries are fully charged. If this situation remains
unchanged, please contact the Horizon Service Center (address
and phone number at the back of this manual) before attempt-
ingtoflyyourmodel.

GENERAL NOTES
DAILY FLIGHT CHECKS
Radio controlled models are a great source of pleasure. Unfortunately,
they can also pose a potential hazard if not maintained and operated
properly. It is imperative that you install your radio control system cor-
rectly.Additionally, your level of piloting competency must be high
enough to ensure that you are able to control your aircraft under all
conditions. If you are a newcomer to radio controlled flying, please
seek help from an experience pilot or your local hobby shop.
Listed below are some safety Do’s and Don’ts that must be followed by
allpilots.
•Ensure that your batteries have been properly charged prior to
initialflight.
•Keep track of the time that the system is turned on so that you will
have an idea of how long you can safely operate your system.
•Perform a ground range check prior to the initial flight of the day.
See the “Daily Flight Checks” section for information on how to do so.
• Check all control surfaces prior to each take off.
•Usefrequencyflags.
•Do not fly your model near spectators, parking areas, or at any other
area that could result in injury to people or damage of property.
•Do not fly during adverse weather conditions. Poor visibility can
cause disorientation and loss of control of your aircraft. Strong winds
cancausesimilarproblems.
•Do not fly unless your frequency is clear.
Warning: Only one transmitter at a time can operate on a given
frequency. If you turn on your transmitter while someone
else is operating a model on your frequency, both pilots will
lose control of their models. Only one person can use a
given frequency at a time. It does not matter if it is AM, FM
or PCM — only one frequency at a time.
•Do not point the transmitter antenna directly toward the model.
The radiation pattern from the tip of the antenna is inherently low.
•Do not take chances. If at any time during flight you observe any
erratic or abnormal operation, land immediately, and do not
resume flight until the cause of the problem has been ascertained
andcorrected.
1. Check the battery voltage on both the transmitter and the receiver
battery packs. Don’t fly below 9.0 volts on the transmitter (orange
and red lights on only) or below 4.7 volts on the receiver. To do so
can cause a crash of your aircraft.
NOTE: Whenyoucheckthereceiverbattery, be sure that you
havepolaritiescorrect on your expanded scale
voltmeter(optional).
2. Check all hardware (linkages, screws, nuts, bolts) prior to each
day’s flight. Be sure that binding does not occur, and that every-
thingisproperlysecured.
3. Ensure that all surfaces are moving in the proper manner.
4. Perform a ground range check before each day’s flying session.
The range check should be as follows:
•Do not extend the transmitter antenna at this time. Turn the
transmitter“on.”
•Turnthemodel“on.”
•Slowly walk away from the model while moving the control
surfaces. The aircraft should function properly at a distance of
60-75feet.
5. Ensure that all trim levers are in the proper location.
6. Check to be sure that all servo pigtails and switch harness plugs
are secure in the receiver. Also, make sure that the switch harness
movescompletelyinbothdirections.
