XP652 MANUAL Decal Sheet
Included with the XP652 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 XP652.
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
XP652 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

The XP652 is a full feature introductory computer
radio that can be used for airplanes and/or
helicopters. This manual is divided into two main
sections — the first for airplanes and the second for
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 XF652 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.

R600 Receiver
•
The R600’s extremely compact size allows it to fit
easily in limited-space airplanes and helicopters.
It’s ultra-low weight keeps overall model weight
down.
•
An independent laboratory ranked the R600
receiver with JR’s patented ABC&W circuitry as
one of the best receivers ever tested in terms of
3IM, 2IM, adjacent channel rejection, signal-tonoise ratio, and on-channel capture point.
•
A special “unwanted interference limiter” ignores
signals outside of the R600’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 in the R600 is state-of-theart 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.
•
The R600 is compatible with all JR FMtransmitting radios.

CHAPTER 4:BATTER Y 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.

The XP652 features a built-in trainer system. The
transmitter can be used as either a master (trainer)
or as a slave (trainee). The XP652 is compatible
with all other current JR radios that have built-in
trainer systems. An optional trainer cord is needed
(JRPA130).
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

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 91)
for lithium battery replacement.

CHAPTER 1:TRANSMITTER CONTROLS • Airplane continued
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
XP652 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.

It is important to correctly install the radio system
in your model. Please read and carefully follow the
suggestions listed below.
1. For added protection, wrap the Rx and the Rx
Nicad 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.

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. Refer to section 7.3 for exponential rate

Accessing the Wing T ype 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 XP652
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
XP652 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 R600 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(System Mode)
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 MODE and CHANNEL button
simultaneously and hold.
2. Turn on the transmitter to enter the System
Mode.
3. Press the MODE 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 XP652 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
XP652 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 XP652 allows you to combine the hold and fail-safe
presets for all six (6) 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 by
you. 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.
1. Turn on the transmitter.
2. Press the MODE and CHANNEL buttons

CHAPTER 6:FUNCTIONS • Airplane continued
Programmable exponential adjustments are offered
on the aileron and elevator channels of your XP652
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
each of the 6 channels. Sub-trim is particularly
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.

direction for each of the 6 channels individually.
The adjustment range is from 0% to 150%. Travel
adjustment is factory set at 100% for all channels.
The travel adjustment value displayed on the screen

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

The XP652 in aircraft mode offers three (3)
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, AILERUDD 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: If a mix switch position other than ON is
selected, it will be necessary to move the selected
switch to the ON, or active, position to adjust the
mixing value. OF will appear on the screen if the
selected mixing switch is in the off position.
The purpose of the mixing offset feature is to redefine
the neutral position of the slave channel to be mixed.
Any desired position may be selected for the offset
reference point. To set the offset position, place the
master channel’s stick to the desired position and
press either the + or - keys.
This position is now stored in the memory and its
offset value from the neutral position of the master
channel is indicated numerically on the LCD display.
Then, the mixing value at the determined offset
position is now set at 0.

XP652 MANUAL Airplane
The Trim Offset Memory Function of your XP652
allows you to test fly your aircraft and correct for
any built-in trim requirements. After you adjust the
aileron, elevator and/or rudder trim levers during
the test flights, the trim levers are no longer in their
center, or neutral, positions. The use of trim offset
allows you to return the trims to their center, or
neutral, positions without readjusting the control
surface linkages mechanically.
This function is very useful when switching from model
to model. It allows your trims to remain in their
neutral positions while retaining their corrections.
Using this feature, you can easily switch among the
five (5) model memories without the need to readjust
for each aircraft’s individual trim requirements.
1. First, test fly your aircraft and adjust the aileron,
elevator and/or rudder trim levers. After all
adjustments have been made, land your airplane.
DO NOT adjust/reposition any of the trim levers at
this time.
CAUTION: Do not attempt to adjust the Trim Offset
Memory Function while your model’s engine is
running. Please stop your aircraft’s engine before
entering the Function Mode.
2. Turn on the transmitter.

CHAPTER 1:TRANSMITTER CONTROLS • Helicopter continued
1.4
NECK STRAP A TT ACHMENT1.6
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
(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 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 XP652 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.

It is important to correctly install the radio system in
your model. Please read and carefully follow the
suggestions listed below.
1. For added protection, wrap the Rx and the Rx
Nicad 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.

The modulation select function enables your XP652
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
XP652 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 R600 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 MODULA TION (System Mode)
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 MODE and CHANNEL button
simultaneously and hold.
2. Turn on the transmitter to enter the System
Mode.
3. Press the MODE 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 XP652 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
XP652 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 XP652 allows you to combine the hold and fail-safe
presets for all six (6) 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 by
you. 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.

Accessing the Dual Rate Function
Dual rate is available for the aileron and elevator

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 • Helicopter (Function Mode) continued
Programmable exponential adjustments are offered
on the aileron and elevator channels of your XP652
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
each of the 6 channels. Sub-trim is particularly
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.

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 3 reference points (L,2, H) and the
stunt, or flight, throttle curve has 2 reference points
(L, 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

CHAPTER 7:FUNCTIONS • Helicopter (Function Mode) continued
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.
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 XP652 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 XP652.

The Stunt Trim Function is a trim position setting for
aileron, elevator and rudder for use during forward
flight maneuvers. This function is activated when in
the Flight Mode 1 position only.
Note: When this function is activated, the trim levers
of the aileron, elevator and rudder are inactive. The
maximum adjustment range is approximately 30
degrees.
To adjust the stunt trim, fly your helicopter in a
straight line at full throttle/pitch in Flight Mode 1.
Center the elevator stick. Note which direction the
helicopter pitches. If the helicopter pitches up, land
the model and add down stunt trim. Repeat until no
pitching occurs.
Next, check the rudder. Add rudder stunt trim until
the tail tracks directly behind the helicopter. Finally,
adjust the aileron stunt trim in the same manner
until no rolling occurs. When properly adjusted, your
helicopter will fly straight and level at full speed with
no correction or trim required.

The CCPM Swashplate Mixing Function (Cyclic
Collective Pitch Mixing) of the XP652 system is
designed to allow the XP652 to be used in model
helicopters that utilize a 120° CCPM-type swashplate
control system. CCPM is a type of pitch mixing where
the three servos are connected directly to the
swashplate of the helicopter and physically move both
in unison and independently for all changes in
pitch/cyclic. Please refer to the diagram below for
proper 120° three servo CCPM identification and
connection.

The Trim Offset Memory Function of your XP652
allows you to test fly your aircraft and correct for
any built-in trim requirements. After you adjust the
aileron, elevator and/or rudder trim levers during
the test flights, the trim levers are no longer in their
center, or neutral, positions. The use of trim offset
allows you to return the trims to their center, or
neutral, positions without readjusting the control
surface linkages mechanically.
This function is very useful when switching from model
to model. It allows your trims to remain in their
neutral positions while retaining their corrections.
Using this feature, you can easily switch among the
five (5) model memories without the need to readjust
for each aircraft’s individual trim requirements.
Note: In helicopter mode, the trim offset memory
values stored will alter the servo position in both
normal and stunt modes. Separate adjustments each
mode is not possible, except through the stunt trim
function (page 83).
1. First, test fly your aircraft and adjust the aileron,
elevator and/or rudder trim levers. After all
adjustments have been made, land your
helicopter. DO NOT adjust/reposition any of the
trim levers at this time.
CAUTION: Do not attempt to adjust the Trim Offset
Memory Function while your model’s engine is
running. Please stop your aircraft’s engine before
entering the Function Mode.

XP652 MANUAL Important Information
IMPORT ANT 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 75–100 feet.
5. Just prior to starting your aircraft, turn “off” your
transmitter and 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 at this time.
6. Ensure that all trim levers are in the proper
location.
7. Check to be sure that all servo pigtails and switch
harness plugs are secured in the receiver. Also,
make sure that the switch harness moves
completely in both directions.

14. WARRANTY AND SERVICE INFORMA TION
WARRANTY COVERAGE
REPAIR SERVICE INSTRUCTIONS
Your new equipment is warranted to the original
purchaser against manufacturer defects in material
and workmanship for one year from the date of
purchase. During this period, Horizon Service Center
will repair or replace, at our discretion, any
component that is found to be factory defective at no
cost to the purchaser. This warranty is limited to the
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 proofof-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.
