4XP662 MANUAL Introduction
Included with the XP662 Radio System is a
switch/function decal sheet. These decals have been
provided as a guide to specific switch positions,
functions, and abbreviations used when operating the
XP662.
The four small decals help identify switch positions and
use for helicopter and aircraft modes.
The large decal at the bottom of the sheet gives
abbreviations and definitions for all of the aircraft and
helicopter functions. The functions decal will prove to be
a helpful guide for making program changes to your
XP662 both in the shop and at the flying field.
We strongly encourage all prospective and current R/C
aircraft pilots join the Academy of Model Aeronautics. The
AMA is a non-profit organization which provides services
to model aircraft pilots. As an AMA member you will
receive a monthly magazine entitled Model Aviation, as
well as a liability insurance plan to cover against possible
accident or injury. All AMA charter aircraft clubs require
individuals to hold a current AMA sporting license prior to
operation of their models. For further information you can

XP662 MANUAL Introduction
The XP662 is a full feature introductory computer
radio for airplanes and/or helicopters. This manual is
divided into two main sections: airplanes and
helicopters. You need only refer to the section that
pertains to the type of model you are programming—
e.g., if you are programming your XF662 for helicopters,
follow the instructions in the helicopter section.
Blank data sheets are included at the end of both
sections. Once you have input all the necessary data
into your transmitter for a particular model, we
strongly recommend that you immediately write
that information down on a copy of the data sheet
provided. This is to insure that, in the rare case of
a memory failure, you will not lose your data.

• Delta wing mixing
• Aileron differential
• V-tail mixing
• Three programmable mixes
• Mixing differential
Helicopter Mode
• Two 3-point throttle curves
• Two 3-point pitch curves (three when throttle
hold is activated)
• Flight mode switch can combine throttle curve,
pitch curve, dual rates, and gyro sensitivity
• Throttle hold
• Revolution mixing up and down
• Programmable mixing
• Optional 120° CCPM Swashplate mixing
• Separate trim setting for all flight modes
R700 Slimline Receiver
• The R700’s extremely compact “slimline” design
allows it to fit easily in limited spaces.
• An independent laboratory ranked the R700
Receiver with JR’s patented ABC&W circuitry as
one of the best receivers ever tested in terms of
3IM, 2IM, signal-to-noise ratio, adjacent channel
rejection, and on-channel capture point.
• The R700 is compatible with all JR FM
transmitting radios.
• A special “unwanted interference limiter” ignores
signals outside of the R700’s band width when
the receiver is on and the transmitter is off.
The limiter also prevents servos from random
glitching when other transmitters are operating
in close proximity.
• The electrical circuitry is state-of-the-art surface
mount technology (SMT). These SMT components
draw less current, thus increasing flying time.
Flush mounting of these components also
reduces the risk of vibration, wear, and damage.

CHAPTER 4:BATTERY CHARGING • Introduction
The pilot lamps 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 JR.
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 warranty. If you are unsure of
compatibilities with your radio, seek expert advice
before doing anything to avoid possible damage.
During the charging operation, the charger’s
temperature is slightly elevated. This is normal.
CHARGER4.2
It is imperative that you fully charge both the
transmitter and the receiver battery packs prior to
each day of flying. For the initial charge, leave the
charger and batteries hooked up for 20–24 hours in
order to fully charge both battery packs to peak
capacity. For subsequent charges, leave the charger
and batteries hooked up overnight (approximately
16 hours).
The charger supplied with this system is designed to
recharge your transmitter battery at a rate of 50mA.
The receiver battery pack will charge at 50mA for the
600mAh airplane battery pack and at 150mA for the
1000mAh helicopter battery pack.
Transmitter Only
The center pin on all JR remote control systems is
negative. Therefore, the center pin on all JR
chargers is negative, not positive. This is different
from any other manufacturers’ chargers and radio
systems. Beware of improper connections based on
“color code” wire leads, as they do not apply in
this instance. You must make certain that the
center pin of your JR transmitter is always connected
to the negative voltage for correct polarity hookup.

14 XP662 MANUAL Introduction
The XP662 features a built-in trainer system. The
transmitter can be used as either a master (trainer) or
as a slave (trainee). The XP662 is compatible with all
other current JR radios that have built-in trainer
systems. An optional Trainer Cord (JRPA130)
is needed .
1. Match the servo reversing and trims of both radios.
2. Plug the optional trainer cord into both transmitters.
3. Turn on the master transmitter.
(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.

XP662 MANUAL Airplane
The XP662 features four digital trim levers with a
direct trim display feature for ultra precise
adjustments. When a trim input is given, the display
screen will automatically change to show the trim
value for current channel being adjusted. Once the
trim change has been completed, the screen will
automatically return to the previous screen display
after 2–3 seconds.
A significant feature found only with Digital Trims is
the ability for the XP662 to automatically store the
trim values in the system memory. This eliminates
the need for previously found software functions like
Trim Offset Memory, Rudder Offset Memory (Heli),
and Stunt Trim (Heli).
In Heli mode, the XP662's digital trims provide a
separate set of trim values for each Flight mode
(Normal, Stunt, and Throttle Hold), which takes the
place of the previously needed Stunt Trim function.
With this feature, the trim levers are active in all
flight modes, and will store the trim values for each
mode independantly. This feature also takes the
place of the previously needed rudder offset
function, since there is now a completely separate
set of trim setting for the Throttle Hold mode.

Note: Your transmitter has a 5-year lithium battery
to protect your pre-programmed data against main
transmitter battery failure. If your system reads
0.0 volts or has an unfamiliar display (service mode)
or your data resets to the factory defaults, return
your transmitter to Horizon Service Center (see
page 85) for lithium battery replacement.
BATTERY CONNECTOR
Use caution when disconnecting/removing the
transmitter battery pack as if the connector is not
properly disconnected, damage to the connector
and/or the radio system can result.

Transmitter Throttle ALT
The Throttle ALT function makes the throttle stick
trim active only when the throttle stick is less than
half throttle. This gives easy, accurate idle adjustments
without affecting the high throttle position.

Transmitter Crystal Replacement Notice
The Federal Communications Commission (FFC) requires that
changes in transmitter frequency must be performed only by an
authorized service technician (Horizon Service Center).Any
transmitter frequency change made by non-certified technician
may result in a violation of the FCC rules.

CHAPTER 1:TRANSMITTER CONTROLS •Airplane
To adjust the control stick length, use a 2mm Allen
wrench to unlock the set screw located inside the end
of the control stick. Turn the set screw counterclockwise
to loosen it, then turn the knurled portion of the stick
to adjust the length. Counterclockwise will lengthen
the stick and clockwise will shorten it. After the
control stick(s) has been adjusted to suit your flying
style, tighten the set screw.
For proper DSC hook-up and operation:
1. Leave the transmitter power switch off. The
transmitter will not transmit any radio
frequency (RF) in this position.
2. Plug the optional DSC Cord (JRPA132) into the
DSC port in the rear of the transmitter.
3. The encoder section of the transmitter will now
be operational and the LCD display will be lit.
4. Plug the other end of the DSC Cord into
the receiver charge receptacle. Turn on the
switch harness.
Note: When installing the optional charging
jack (JRPA024), be sure to hook the charging jack
receptacle securely into the switch harness
charge cord.
Why you should use the DSC function:
1. The DSC enables you to check the control
surfaces of your airplane without drawing the
fully operational 200mAh from your transmitter
battery pack. Instead, you will only draw 70mAh
when using the DSC function.
Note: You will need to purchase (separately)
both the DSC Cord (JRPA132) and the JR Deluxe
Switch Harness (JRPA001) to make use of the
XP662 DSC function.
2. The DSC function allows you to make final
adjustments to your airplane or helicopter
without transmitting any radio signals.
Therefore, if another pilot is flying on your
frequency, you can still adjust your aircraft and
not interfere with the other aircraft.
Note: Under no circumstances should you
attempt to fly your aircraft with the DSC Cord
plugged in! This feature is for bench checking
your aircraft only.
There is an eye hook on the front of the transmitter
for attaching an optional neck strap (JRPA023). The
eye hook is precisely positioned (see Section 1.1)
so that the transmitter will be perfectly balanced
when a neck strap is used.

Please read and carefully follow these suggestions.
1. For added protection, wrap the RX and the RX
Ni-Cd in foam rubber that is at least 1/4” thick.
2. Run the RX antenna through the fuselage and
make sure it is fully extended. Never cut or
bundle your RX antenna—this will decrease
range and performance.
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).
4. 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.
5. Before installing servo output arms, make sure
the servo is in its neutral position.
6. 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 that the switch operates freely and is
capable of traveling its full distance.
7. With your model sitting on the ground and
the transmitter antenna collapsed, check
that your system works at a distance of
75 to 100 feet.
If your system stops functioning at a distance
that is shorter than listed above, please contact
the Horizon Service Center for further
information prior to flying your model.

When the transmitter battery drops below 9.0 volts,
the display will start to flash “BAT” and an audible
alarm will sound for eight beeps. These warnings
mean you should land your aircraft immediately.
Note: During the period that the battery alarm is
flashing, the input buttons will not function. If you
are currently in the function mode, the transmitter
will exit automatically and return to the normal
display (see Section 5.1).
