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
contact the AMA at:
Academy of Model Aeronautics

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.

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.

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 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.

3984 JR XP662 Manual 1/21/02 1:11 PM Page 16
17
XP662 MANUAL Airplane
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.

Your XP662 incorporates a special THROTTLE CUT
button located on the upper right face of the
transmitter. This feature is designed to immediately
override any current throttle/trim position and will
immediately return the throttle servo to the full low
position. This feature will allow the engine to be
automatically stopped in case of emergency, or in
the event of a crash. When adjusting your throttle
linkage, please check to ensure that when the
THROTTLE CUT button is pushed, the throttle
servo will move the carburetor barrel to the full
closed position.
Note: In some cases it will be necessary to adjust
the engines barrel stop screw so that the
carburetor can be fully closed. Please refer to your
engine instructions for more detail.
The Throttle Cut function is designed to function
only which the throttle stick is below the 1/2 position,
and a trim value has been assigned to the throttle
trim levers.

The dual rate switch position is selectable and the
elevator and aileron dual rates can be combined on
one switch. This allows a single switch to be used
when moving from high rates for wild maneuvers to
low rates for mild maneuvers. Exponential Rate
(EXP) is also available for both aileron and elevator
and works in conjunction with the dual rate function
to provide mild control movements around neutral
while allowing maximum servo travel. This reduces
sensitivity in the middle portion of the stick control
and still allows full travel at the end of the stick control.

XP662 MANUAL Airplane
Accessing the Wing Type Selection Function
Flaperon, V-tail, and Delta Mixing are available for
specialty aircraft that require those functions. The
flaperon feature mixes flaps with ailerons so the
ailerons can be drooped for takeoffs and landings
while still functioning fully as ailerons. V-Tail Mixing
combines rudder and elevator for V-Tail operations.
The Delta Wing function allows the aileron to also
act as the elevator, while retaining independent use
of both functions. The Delta Wing function allows the
ailerons to also act as the elevator, while retaining
independent use of both functions.
Flaperon Setup
When using flaperon mixing, two servos (one for
each aileron) must be used. Connect the left aileron
servo to channel #6 (Aux 1) and the right aileron
servo to channel #2 (Aile) in the receiver. Individual
functions (e.g., servo reversing, sub-trims, etc.) are
still available for each of the channels. Use sub-trims
for individual neutral adjustment. Adjust the aileron
travel values by increasing or decreasing the aileron
dual rate. Flap adjustments are made with flap
left/right travel adjustment described in Section 7.5.
Also see Aileron Differential in Section 6.18.
V-Tail
V-Tail Mixing requires two servos. Connect the left
tail servo to channel #3 (Elev) and the right tail servo
to channel #4 (Rudd) in the receiver. Individual
functions (e.g., servo reversing, sub-trims, etc.) are
available for each servo. Use sub-trims for individual
neutral adjustments described in Section 7.4. V-Tail
elevator travel is adjusted by elevator dual rates
described in Section 7.2.
Delta-Wing Mixing
Delta or Elevon Mixing as it is commonly known, is
the final wing mixing selection in your XP652. This
style of aircraft also employs two wing servos.
However, in essence, there is not an elevator present.
Instead, at an elevator stick input, the two wing
servos function in conjunction with one another in
the same direction to create an up/down movement
of the aircraft. Also, when an aileron control is given,
the two wing servos move in opposite directions to
function as ailerons as well.

The modulation select function enables your XP662
to transmit to a variety of JR receivers that are
already, or may soon be, in existence. You can select
from either PPM (FM), Z-PCM or S-PCM,depending
on the central processing unit within your receiver to
utilize existing receivers, or to upgrade your XP662
flight pack for future models. Your system comes
factory preset in the FM or PPM (Pulse Position
Modulation) position so that it is compatible with
the included R700 FM receiver.
Please refer to the receiver compatibility chart below when
selecting the modulation type for various JR receivers.
Note: Once the proper modulation has been
selected for a specific model number, the
modulation type will remain the same for that model
number, even during model number/type changes. In
other words, if you have one model on FM/PPM and
one model on PCM, the system will automatically
change modulation types once the correct
modulation has been selected for that model.

FAIL-SAFE/HOLD FUNCTION IN Z-PCM MODULATION
6.9
The Hold function is automatically activated when
the radio is turned on and is in the Z-PCM modulation.
This function stops (or holds) the servos in the
positions they were in just prior to the interference.
Therefore, your airplane maintains the position held
immediately before the interference was experienced.
When a clear signal is restored, the Hold function
releases, and control of the airplane returns to you.
If you would prefer your control surfaces to move to
a chosen position during a loss of signal, please refer
to the time delay/memory section below.
Hold (Z-PCM)
Accessing Fail-Safe/Hold (Z-PCM)
When the Fail-Safe function is activated (i.e., when
the signal is interrupted), the transmitter automatically
moves each servo to a preset position. The position
that each servo assumes is determined by you, as is
the time length of interference that must occur
before servo movement.
After the interference has ceased, control of the
airplane returns immediately to you.
There are three time delays to choose from: 1/3 (0.3)
second, 1/2 (0.5) second and 1.0 second. These time
delays are the amount of time it takes, starting the
moment the interference occurs, until the servos
assume their preset positions.
1. Press the SCROLL and INCREASE button
simultaneously and hold.
2. Turn on the transmitter to enter the System mode.
3. Press the SCROLL button until “FST” appears on
the screen.
Note: If Fail-Safe does not appear on your LCD, it is
because you are transmitting in PPM. Fail-Safe is not
applicable in the PPM mode. Refer to the Modulation
Mode Selection section for more information.
The Fail-Safe/Hold function is available only when
you use the XP662 transmitter in either of the
PCM modulations: S-PCM or Z-PCM. This function is
designed to help minimize damage to your airplane
during a loss of signal to the receiver. The servos
either assume the fail-safe presets or hold the last
good signal position.
Note: In the PCM modulations, the Fail-Safe/Hold
function cannot be totally disabled so that the servos
will react to interference in the same way as they do in
a PPM system. This is only possible with the use of a
PPM receiver and the transmitter in the PPM modulation.
Note: Since the actual screen appearance varies,
depending on the modulation of your radio, refer
to the appropriate modulation section which follows
(Z-PCM, S-PCM).
As noted earlier, if you are in the PPM modulation,
the Fail-Safe/Hold function is not applicable.
Therefore, the Fail-Safe/Hold function will not appear
on your LCD in the PPM mode.
Refer to the Modulation Selection section for more
information pertaining to the broadcast signal of
your XP662 transmitter.

The Hold function is automatically activated when
the radio is turned on and in the S-PCM modulation.
This function stops (or holds) the servos in the
positions they were in just prior to the interference.
Therefore, your aircraft maintains the position held
immediately before the interference was experienced.
When a clear signal is restored, the Hold function
releases, and control of the airplane returns to you.
The XP662 allows you to combine the hold and fail-
safe presets for all six channels on the receiver. You
can select fail-safe or hold independently for all
channels on your aircraft. In other words, some
channels will hold their last clear signal position,
while others assume the preset position. Once the
fail-safe has been activated by signal interruption
(interference), the transmitter automatically moves
the servos to a preset position. The predetermined
servo positions are set byyou. In the S-PCM fail-safe,
the time delay (the amount of time it takes, starting
the moment the interference occurs, until the servos
assume the preset positions) is fixed at .3, or 1/3, second.
After the interference has ceased, normal operation
of the airplane returns to you immediately.

Dual rate is available for the aileron and elevator
channels. The purpose of this function is to allow for
in-flight selection of two preset servo travels for each
of these channels. The amount of travel is adjustable
from 0-125%. The factory settings for both switch
positions (0 and 1) is 100%. Either position may be
selected as the low or high rate by placing the
switches in the desired position and adjusting the
value for that position. Operation of these switches
is described in Section 6.3.
Different types of maneuvers require varying
amounts of control movements. Snap rolls require
large control movements, while smooth maneuvers
like long slow rolls are best performed with smaller
control movements. Dual rates allow you to change
the control movements in flight at the flip of a
switch. This allows you to execute maneuvers
requiring both radical control movements and small
control movements during a single flight.

CHAPTER 7:FUNCTIONS (FUNCTION MODE) • Airplane
Programmable exponential adjustments are offered
on the aileron and elevator channels of your XP662
system. Exponential is a function that allows you to
tailor the response rate of the controls as compared
to the stick inputs. The purpose of exponential is to
reduce the sensitivity in the middle portion of stick
movement, while still allowing full travel at the end
of the stick movement. In other words, the end result
(travel) remains the same, although exponential
changes the rate at which it achieves this travel.
The adjustable range of the Exponential function is
from 0–100%. Zero percent (0%) is linear stick control
which means that the response rate is equal
throughout the stick control. One hundred percent
(100%) is full exponential. The larger the exponential
value, the less servo action, or sensitivity, you will
notice around the neutral setting.
Note: The Exponential function operates in
conjunction with the Dual Rate function. It is
imperative to understand the Dual Rate function
prior to adjusting the exponential values.
Exponential may be selected independently for
either the high or low rate (position 0 or 1) or both.

Sub-trim is an electronic trim that is available for

useful as it allows the mechanical trim levers to be
returned to their neutral positions by adjusting/
changing the servo’s neutral position electronically,
without the need to mechanically adjust the specific
control linkage. This allows the same mechanical
trim lever settings between the four models you can
control with this radio system. Sub-trim can also
allow additional trim travel when mechanical trims
do not provide enough movement.
Note: It is recommended to use as little subtrim as
possible for adjustment. If more that 20–30 points
are required, is it suggested that a mechanical
linkage adjustment be performed.

CHAPTER 7:FUNCTIONS (FUNCTION MODE) • Airplane
When the flaps are deployed, most airplanes exhibit
pitching tendencies (most pitch nose up). Elevator
offset trim is designed to prevent this pitching. Flap
to elevator offset trim automatically retrims the elevator
to a preset value when the flap switch is activated.
Note: Flap-to-elevator offset trim is also useful as a
dual elevator trim even for airplanes without flaps. This
is especially helpful for sailplanes that require one trim
setting for launch and another trim setting for flight.

XP662 MANUAL Airplane
The XP662 in aircraft mode offers three
programmable mixes to be used for a number of
different purposes. The functions allow mixing any
one channel to any other channel.
The mix can remain ON at all times, or be switched
OFF in flight using a number of different switches.
(Refer to Chart A). Each channel is identified by
channel numbers 1-6 (i.e., 2 = aileron, 4 = rudder,
etc.—See Chart B) The channel appearing first is
known as the “master channel,” or the channel to
which you want to mix. The second channel is known
as the “slave channel” or the channel that is being
mixed into the master channel. For example, “AILE-
RUDD” would indicate aileron-to-rudder mixing.
Each time the aileron stick is moved, the aileron will
deflect, and the rudder will automatically move in
the direction and to the value input. Mixing is
proportional, so small inputs of the master channel
will produce small outputs of the slave channel.
Each programmable mix has a mixing “offset.” The
purpose of the mixing offset is to redefine the
neutral position of the slave channel.

Note: Your transmitter has a 5-year lithium battery
to protect your pre-programmed data against main

CONTROL STICK LENGTH ADJUSTMENT
CHAPTER 1:TRANSMITTER CONTROLS • Helicopter
1.4
NECK STRAP ATTACHMENT1.6
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 back.
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 (JRPA025), 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 aircraft 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 on the ground and the trans-
mitter 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.

The modulation select function enables your XP662
to transmit to a variety of JR receivers that are
already, or may soon be, in existence. You can select
from either PPM (FM), Z-PCM or S-PCM,depending
on the central processing unit within your receiver to
utilize existing receivers, or to upgrade your XP662
flight pack for future models. Your system comes
factory preset in the FM or PPM (Pulse Position
Modulation) position so that it is compatible with
the included R700 FM receiver.
Please refer to the receiver compatibility chart
below when selecting the modulation type for
various JR receivers.
Note: Once the proper modulation has been
selected for a specific model number, the modulation
type will remain the same for that model number,
even during model number/type changes. In other
words, if you have one model on FM/PPM and one
model on PCM, the system will automatically change
modulation types once the correct modulation has
been selected for that model.

3984 JR XP662 Manual 1/21/02 1:11 PM Page 62
When the Fail-Safe function is activated (i.e., when
the signal is interrupted), the transmitter automatically
moves each servo to a preset position. The position
that each servo assumes is determined by you, as is
the time length of interference that must occur
before servo movement.
After the interference has ceased, control of the
airplane returns immediately to you.
There are three time delays to choose from: 1/3 (0.3)
second, 1/2(0.5) second and 1.0 second. These time
delays are the amount of time it takes, starting the
moment the interference occurs, until the servos
assume their preset positions.
1. Press the SCROLL and INCREASE buttons
simultaneously and hold.
2. Turn on the transmitter to enter the System mode.
3. Press the SCROLL button until “FST” appears on
the screen.
Note: If “Fail-Safe” does not appear on your LCD, it
is because you are transmitting in PPM. Fail-Safe is
not applicable in the PPM mode. Refer to the
Modulation Mode Selection section for
more information.

FAIL-SAFE/HOLD FUNCTION IN Z-PCM MODULATION
6.9
The Hold function is automatically activated when
the radio is turned on and is in the Z-PCM modulation.
This function stops (or holds) the servos in the
positions they were in just prior to the interference.
Therefore, your airplane maintains the position held
immediately before the interference was experienced.
When a clear signal is restored, the Hold function
releases, and control of the airplane returns to you.
If you would prefer your control surfaces to move to
a chosen position during a loss of signal, please refer
to the time delay/memory section below.
Hold (Z-PCM)
Accessing Fail-Safe/Hold (Z-PCM)
The Fail-Safe/Hold function is available only when
you use the XP662 transmitter in either of the
PCM modulations: S-PCM or Z-PCM. This function is
designed to help minimize damage to your airplane
during a loss of signal to the receiver. The servos
either assume the fail-safe presets or hold the last
good signal position.
Note: In the PCM modulations, the Fail-Safe/Hold
function cannot be totally disabled so that the
servos will react to interference in the same way as
they do in a PPM system. This is only possible with
the use of a PPM receiver and the transmitter in the
PPM modulation.
Note: Since the actual screen appearance varies,
depending on the modulation of your radio, refer
to the appropriate modulation section which follows
(Z-PCM, S-PCM).
As noted earlier, if you are in the PPM modulation,
the Fail-Safe/Hold function is not applicable.
Therefore, the Fail-Safe/Hold function will not appear
on your LCD in the PPM mode.
Refer to the Modulation Selection section for more
information pertaining to the broadcast signal of
your XP662 transmitter.

The Hold function is automatically activated when
the radio is turned on and in the S-PCM modulation.
This function stops (or holds) the servos in the
positions they were in just prior to the interference.
Therefore, your aircraft maintains the position held
immediately before the interference was experienced.
When a clear signal is restored, the hold function
releases, and control of the airplane returns to you.
The XP662 allows you to combine the hold and fail-
safe presets for all six channels on the receiver you
can select fail-safe or hold independently for all
channels on your aircraft. In other words, some
channels will hold their last clear signal position,
while others assume the preset position. Once the
fail-safe has been activated by signal interruption
(interference), the transmitter automatically moves
the servos to a preset position. The predetermined
servo positions are set byyou. In the S-PCM fail-safe,
the time delay (the amount of time it takes, starting
the moment the interference occurs, until the servos
assume the preset positions) is fixed at .3, or 1/3, second.
After the interference has ceased, normal operation

Accessing the Dual Rate Function
Dual rate is available for the aileron and elevator
channels. The purpose of this function is to allow for
in-flight selection of two preset servo travels for each
of these channels. The amount of travel is adjustable
from 0-125%. The factory settings for both switch
positions (0 and 1) is 100%. Either position may be
selected as the low or high rate by placing the
switches in the desired position and adjusting the
value for that position. Operation of these switches
is described in Section 6.3.
Different types of maneuvers require varying
amounts of control movements. Snap rolls require
large control movements, while smooth maneuvers
like long slow rolls are best performed with smaller
control movements. Dual rates allow you to change
the control movements in flight at the flip of a
switch. This allows you to execute maneuvers
requiring both radical control movements and small
control movements during a single flight.

CHAPTER 7:FUNCTIONS (FUNCTION MODE) • Helicopter
Programmable exponential adjustments are offered
on the aileron and elevator channels of your XP662
system. Exponential is a function that allows you to
tailor the response rate of the controls as compared
to the stick inputs. The purpose of exponential is to
reduce the sensitivity in the middle portion of stick
movement, while still allowing full travel at the end
of the stick movement. In other words, the end result
(travel) remains the same, although exponential
changes the rate at which it achieves this travel.
The adjustable range of the Exponential function is
from 0–100%. Zero percent (0%) is linear stick
control which means that the response rate is equal
throughout the stick control. One hundred percent
(100%) is full exponential. The larger the exponential
value, the less servo action, or sensitivity, you will
notice around the neutral setting.
Note: The Exponential function operates in
conjunction with the Dual Rate function. It is
imperative to understand the Dual Rate Function
prior to adjusting the exponential values.
Exponential may be selected independently for
either the high or low rate (position 0 or 1) or both.

useful as it allows the mechanical trim levers to be
returned to their neutral positions by adjusting
/changing the servo’s neutral position electronically,
without the need to mechanically adjust the specific
control linkage. This allows the same mechanical
trim lever settings between the five models you can
control with this radio system. Sub-trim can also
allow additional trim travel when mechanical trims
do not provide enough movement.
Note: It is recommended to use as little subtrim as
possible for adjustment. If more that 20–30 points
are required, is it suggested that a mechanical
linkage adjustment be performed.

The XP652 offers three separate pitch curves with
three adjustable reference points per curve. This
function allocates a separate pitch curve setting
during Normal, Stunt, and Throttle Hold modes to
maximize flight performance. Once the pitch curves
are established, each can be activated in flight using
the two-position flight mode switch and the throttle
hold switch.
Each of the three reference points of the pitch curve
are independently adjustable from 0–100%. These
three points correspond to the low, middle, and high
positions of the throttle stick (collective).
The graph below shows samples of pitch curves in
the Normal (N), Stunt (S) and Throttle Hold (H)
conditions. The factory preset values for all three
pitch curves are: Low 0%, Middle 50%, and High
100%.

Accessing the Throttle Curve Function
Adjustment of the throttle curve is very similar to
the pitch curve adjustment described in the
preceding section. A thorough understanding of the
pitch curve section will make the throttle curve
section easier to understand.
There are two independent types of throttle curves
available—normal and stunt. The normal or hover
throttle curve has three reference points (L,2, H) and
the stunt or flight throttle curve has two reference
points (L and 2).
The two throttle curves are activated by the flight
mode switch located on the top left rear corner of
the transmitter. The throttle curve is in the normal
condition when the flight mode switch is in the back
position. The throttle curve is in the stunt condition
when the flight mode switch is in the forward position.
Note: In Stunt mode (S), the high position of the
throttle curve is preset to 100%, and is not adjustable.

CHAPTER 7:FUNCTIONS (FUNCTION MODE) • Helicopter
The Revolution Mixing function combines tail rotor
input with the throttle/collective function to
counteract the torque created by the main rotor
blades. When properly adjusted, the helicopter will
climb and descend without a tendency to yaw in
either direction. Revolution mixing is for use with
non heading lock gyros only.
Since the torque created by the main rotor blades
varies with different throttle/pitch settings, it is
necessary for the tail rotor blades to change pitch at
the same time. The “U” or up mixing adjusts the tail
rotor compensation from the mid to high throttle
stick setting. The “D” or down mixing adjusts the tail
rotor compensation from the mid to the low throttle
stick setting.
Thus, if you were to move the throttle from the low
to high positions, the tail rotor servo will move from
the “D” to the “U” settings.
Revolution Mixing Set-up Procedure
First, set up the helicopter so that it will maintain a
stable hover with the tail rotor trim in the center
position. Next, bring the helicopter into a steady
vertical climb. The body of the helicopter will move
in the opposite direction to the main rotor rotation.
Increase the “U” or up mixing until the helicopter
climbs without the tendency to rotate. At a safe altitude,
reduce the throttle. The helicopter will descend, and
the body will turn in the same direction as the main
rotor blades. Increase the “D” or down mixing until
the helicopter descends without the tendency to rotate.

The XP662 in Helicopter mode offers one (1)
programmable mix to be used for a number of
different purposes. The functions allow mixing any
one channel to any other channel.
The mix can remain on at all times or be switched off
in flight using a number of different switches. (Refer
to Chart A). Each channel is identified by channel
numbers 1-6 (i.e., 2 = aileron, 4 = rudder, etc. —see
Chart B) The channel appearing first is known as the
Master Channel or the channel to which you want to
mix. The second channel is known as the Slave
Channel or the channel that is being mixed into the
Master Channel. For example, “ELEV-AILE” would
indicate elevator-to-aileron mixing each time the
elevator stick is moved, the elevator will deflect, and
the aileron will automatically move in the direction
and to the value input. Mixing is proportional, so
small inputs of the master channel will produce
small outputs of the slave channel. Each
programmable mix has a mixing “offset.” The purpose
of the mixing offset is to redefine the neutral
position of the slave channel.
The elevator-aileron mix mentioned above is most
commonly used to help trim the helicopter for proper
“loop tracking.” This type of mix should be used only
by pilots who are comfortable with their
programming abilities with the XP662.

The 120° CCPM system requires the use of three
servos to operate, Aileron, Elevator, and AUX 1
(Pitch). The labeling of these servos can become quite
confusing because with the CCPM function, the three
servos no longer work independently, but rather as a
team, and their functions are now combined. For this
reason, we will refer to the three servos in the
following manner:
Aileron Servo: We will refer to this servo as the
“Left” servo. The channel number for this servo
when using a JR radio is CH2.
Elevator Servo: We will refer to this servo as the
“Front” servo. The channel number for this servo
when using a JR radio is CH3.
AUX 1 (Pitch) Servo: We will refer to this servo as
the “Right” servo. The channel number for this
servo when using a JR radio is CH6.
Please refer to the CCPM connections chart below for
clarification. For non-JR radios, please consult your
radio instructions for proper connection.

HOW 120 CCPM WORKS
7.13
CHAPTER 7:FUNCTIONS (FUNCTION MODE) • Helicopter
As mentioned previously, 120° Three-Servo CCPM
relies on the radio’s special CCPM swashplate mixing,
rather than a conventional mechanical mixer that is
utilized to achieve the same results.
The radio’s 120° Three-Servo CCPM function
automatically mixes the three servos to provide the
correct mixing inputs for aileron (roll), elevator
(pitch), and collective. The following is an example of
how each control input affects the servo’s movement:
1. Collective
When a collective pitch input is given, all three
servos (A, B, and C) move together in the same
direction, at equal amounts, to raise and lower the
swashplate while keeping the swashplate level.
During this function, all three servos travel at the
same value (100%) so that the swashplate can
remain level during the increase and decrease in
pitch. As mentioned, this mixing of the three servos
is achieved through the radio’s CCPM program.
2. Elevator (Pitch)
When an elevator input is given, all three servos
must move to tilt the swashplate fore and aft, but
their directions vary. The two rear servos (B and C)
move together in the same direction, while the
front servo (A) moves in the opposite direction. For
example, when an up elevator (back cyclic)
command is given, the two rear servos (B and C)
will move downward, while the front servo (A)
moves upward so that the swashplate will tilt aft.
During this function, the front servo (A) travels at
100%, while the two rear servos (B and C) travel at
50% (1/2 the travel value) of the front servo. This
difference in travel is necessary due to the fact that
the position of the front control ball is two times
the distance of the two rear control ball position as
measured from the center of the swashplate. As
mentioned, this mixing of the three servos is also
achieved through the radio’s CCPM program.
3. Aileron (Roll)
When an aileron (roll) input is given, the two rear
servos (B and C) travel in opposite directions, while
the front servo (A) remains motionless. For
example, when a left aileron (roll) command is
given, the left rear servo (C) will move downward,
while the right rear servo (B) will move upward to
tilt the swashplate to the left. As mentioned, the
front servo (A) will remain motionless. The travel
value for each of the two rear servos is 100%.
Please refer to the diagram below for clarification.

HOW 120 CCPM WORKS (continued)
7.13
CHAPTER 7:FUNCTIONS (FUNCTION MODE) • Helicopter
The JR 120° CCPM or Cyclic/Collective Pitch Mixing
system offers the user a control system that can
accomplish the same control inputs as the One-Servo
Standard system, but with increased precision and
reduced complexity.
As with the One-Servo system, the JR CCPM system
utilizes three servos for the three main controls:
aileron (roll), elevator (pitch) and collective. The
CCPM lower swashplate ring is designed with only
three control balls, spaced at 120° from each other,
hence the 120° CCPM designation. Although the
control balls are not at 90° as in the standard system,
the aileron (roll) axis is still parallel to the main
mechanics of the helicopter, and the elevator (pitch)
axis still functions at 90° to the mechanics as does
the One-Servo System. Please refer to the diagram
below for clarification.
The main and important difference in the way that
these two systems operate is that unlike the One-
Servo system where the three servos work completely
independent from each other, the CCPM systems work
as a team to achieve the same control inputs. For
example, if an aileron (roll) input is given, two servos
work together to move the swashplate left and right. If
an elevator (pitch) input is given, all three servos work
together to move the swashplate fore and aft. For
collective, it’s also the strength of three servos that
will move the swashplate up and down the main rotor
shaft. With two to three servos working at the same
time during any given control input, servo torque is
maximized and servo centering is also increased. In
addition to these benefits, CCPM achieves these
control responses without the need for complex
mechanical mixing systems that require many more
control rods and parts to set up.
This amazing CCPM control is achieved through
special CCPM Swashplate Mixing that is pre-programmed
into many of today’s popular radio systems.
Since the 120° CCPM function is pre-programmed,
CCPM is no more complicated to set up than a
conventional One-Servo Standard system. When you
factor in the reduced parts count and easy
programming, CCPM is actually easier to set up and
operate than many conventional systems.

84 XP662 MANUAL Important Information
IMPORTANT INFORMATION
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 correctly. 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 experienced pilot or
your local hobby shop.
Listed below are some safety Dos and Don’ts that
must be followed by all pilots:
• Ensure that your batteries have been properly
charged prior to initial flight.
• 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 below for information on how to do so.
• Check all control surfaces prior to each takeoff.
• Use frequency flags.
• 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 can
cause similar problems.
• 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
and corrected.
1. Check the battery voltage on both the transmitter
and the receiver battery packs. Do not fly below
9.0 volts on the transmitter or below 4.7 volts
on the receiver. To do so can cause a crash of
your aircraft.
Note: When you check these batteries, ensure that
you have the polarities correct on your expanded
scale voltmeter.
2. Check all hardware (linkages, screws, nuts, bolts)
prior to each day’s flight. Be sure that binding does
not occur and that everything is properly secured.
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.
• Turn the model on.
• Slowly walk away from the model while moving
the control surfaces. The aircraft should
function properly at a distance of 75 to 100 feet.
5. Prior to starting your aircraft, turn off your
transmitter then turn it back on. Do this each
time you start your aircraft. If any critical
switches are on without your knowledge, the
transmitter alarm will warn you.
6. Ensure that all trim levers are in the proper location.
7. Be sure that all servo pigtails and switch harness
plugs are secured in the receiver. Make sure
that the switch harness moves completely in
both directions.

original purchaser of the unit and is not transferable.
This warranty does not apply to any unit which has
been improperly installed, mishandled, abused, or
damaged in a crash, or to any unit which has been
repaired or altered by any unauthorized agencies.
Under no circumstances will the buyer be entitled to
consequential or incidental damages. This limited
warranty gives you specific legal rights; you also have
other rights which may vary from state to state. As with
all fine electronic equipment, do not subject your unit
to extreme temperatures, humidity or moisture. Do
not leave it in direct sunlight for long periods of time.
In the event that your equipment needs service,
please follow the instructions listed below:
1. Check all on/off switches to be sure they are off.
This will speed the repair process of checking
battery condition.
2. Return your system components only
(transmitter, receiver, servos, etc.). Do not return
your system installed in a model car, boat,
plane, etc.
3. Use the original carton/packaging (molded foam
container), or equivalent, to ship your unit. Do
not use the carton itself as a shipping carton; you
should package the equipment carton within a
sturdy shipping container using additional packing
material to safeguard against damage during
transit. Include complete name and address
information inside the carton, as well as clearly
writing it on the outer label/return address area.
Ship your equipment fully insured and prepaid.
Horizon Service Center is not responsible for any
damages incurred during shipping.
4. Include detailed information explaining your
operation of the equipment and problem(s)
encountered. Provide an itemized list of equipment
enclosed and identify any particular area/function
which may better assist our technicians in
addressing your concerns. Date your correspondence
and include your name, mailing address, and a
phone number where you can be reached during
the business day.
5. Warranty Repairs. To receive warranty service
you must include a legible photocopy of your
original dated sales receipt to verify your proof-
of-purchase date. Providing that warranty
conditions have been met, your radio will be
repaired without charge.
6. Normal Non-Warranty Repairs. Should your
repair cost exceed 50% of the retail purchase
cost, you will be provided with an estimate
advising you of your options.
Within your letter, advise us of the payment method
you prefer to use. Horizon Service Center accepts
VISA or MasterCard, please include your card
number and expiration date.
