Using This Manual
JR’s PCM10X offers the ultimate in programming capability while still retaining the “user friendliness” for which JR’s original PCM10, 10S,
10Sx, and 10SxII systems are known. While many of the screens are similar to the previous generation systems, it’ s important that you read
and understand this manual to fully appreciate and take advantage of the capabilities of the features available with the
PCM10X.
Your new JR PCM10X is also equipped with JR’s new innovative 3+1 Digital Trim System. These new 3+1 Digital Trims offer the best of
both worlds—digital trim levers on aileron, elevator, and rudder for maximum efficiency and precision, while retaining the mechanical trim
on the throttle for safety and immediate visual reference.
Refer to the T able of Contents below to find out where to look for answers to your particular questions. The features are discussed in the same
order as they appear on the LCD of your screen (numerically). An explanation of the use and purpose of each feature is provided, followed by
a labeled illustration of its LCD display. Additionally, a step-by-step example is included to clarify the set-up procedure of the feature.
You will find a blank data sheet at the end of this manual. Once you have entered all data for a particular model, we recommend that you also
record it on the data sheet. If you should experience a memory battery failure or wish to make changes to the current settings, this extra step
will save you a lot of time.

• Up to 5 available flight modes are selectable via a programmable switch location. Each flight mode allows the adjustment and selection of nearly every parameter to alter the characteristics of the helicopter for differing flight regimes (e.g., FAI
type aerobatics, 3D aerobatics, etc.). Code 17.
• Digital trims on aileron, elevator and rudder feature
adjustable trim rates, allowing the increments of each trim step to
be adjusted to the desired amount. When adjusting the digital
trims, a tone is emitted that signals each trim step. The pitch of
the tone changes based on trim position (left trim – high pitch,
right trim – low pitch ) so that the approximate trim position can
be audibly known without having to look at the transmitter.
• Digital trim positions are automatically displayed on the
Info screen. A bar graph or a digital value can be selected to display the trim position.
• Digital trim positions are automatically stored in memory
and recalled when switching from model to model.
• A mechanical trimmer is included on throttle, offering the
ease and convenience of a visual reference during engine startup.
The throttle trim rate is adjustable in Code 83.
• A DataSafe
TM
is included (complete systems only) that
allows the 10X to download model memory to any Windows
95
®
and later PC for infinite model storage and security . See the
enclosed Data-Safe manual for instructions.
• A removable 1100mAh Sanyo
®
battery pack gives nearly 5
hours of continuous use. A built-in charge receptacle allows the
battery to be charged separately or in the transmitter .
• Rudder-to-throttle mixing has separate adjustable values left
and right and can be activated in any or all flight modes.
• Aileron-to-throttle mixing has separate adjustable values
right and left and can be activated in any or all flight modes.
• Elevator-to-throttle mix has separate adjustable values up
and down and can be activated in any or all flight modes.
• Gyro gain function, Code 44, allows you to combine rudder
to Aux 3 mixes to Code 44 (gyro gain adjustment), allowing stick
priority gain control. Stick priority gain values are also displayed
on this screen.
• Five programmable tail rotor curves are available that allow
up to 7 points to be stored. The mix rate function allows the tail
curve to be expanded (1/1, 1/2, 1/4, 1/10) for a more accurate tail
adjustment.
• Swashplate mixing features independent aileron-to-elevator
and elevator-to-aileron mixing values and can be activated in any
or all fight modes. 120° and 140° 3 servo CCPM mixing is also
available.
• A servo monitor visually displays each of the ten servo
positions. This handy feature is especially useful during the setup
of mixes. CODE 75.
• The programming of the
PCM10X allows up to five flight
modes with independent throttle and pitch curves, tail rotor curve
mixing, and pre-programmed Aile/Elev/Rudd-Throttle mixing.
• An exponential function is available on the throttle and
pitch curves that automatically “smoothes out” the curve.
• When using the
PCM
10X in conjunction with a JR Piezo
Gyro, three gyro rates are available and can be selected in the six
types of flight modes (N, 1, 2, 3, 4, Hold).
• The micro computer system employs an extra large and
clearly visible
LCD touch display that makes the PCM10X the
fastest and easiest radio control transmitter system in the world
to program.
• Adjustable stick tension enables you to customize the feel
of the gimbals for more precise flying. Refer to Section 3.5 of
this manual for instructions on adjusting stick tension.
• The new central processing unit (
CPU) in the PCM10X
allows for compatibility never before available in any radio system. This transmitter can broadcast in two types of
PCM— the
new S-series (1024)
PCM and the well-known Z-series (512) PCM
— as well as PPM. This enables you to use virtually all of your
current
FM JR receivers.
•The
PCM10X is capable of storing ten (10) models in its
memory . The ten (10) model memory allows you to completely
program ten models into the
PCM10X. Or, by using more than
one program for a single aircraft, you are able to have different
set-ups available.
•The
PCM10X is equipped with a five-year lithium battery
back-up to prevent memory loss if your transmitter battery pack
should discharge completely or if the transmitter battery pack
should inadvertently be removed from the transmitter.
• A fail-safe feature when modulating in the S-series
PCM
allows you to select hold or fail-safe preset positions for the first
eight channels individually .
• Direct Servo Control (
DSC) permits operation of all controls
and servos without generating a radio signal.
• The graphic multi-point pitch and throttle curve means you
can set the pitch for 7 selectable stick positions.
• The
PCM10X offers a choice of dual rate, exponential or vari-
able trace rate (
VTR) movement for the aileron, elevator and rud-
der channels.
•The
PCM10X has eight free programmable mixes, four of
which allow the programming of up to a seven point curve that
can be turned on/off in any flight mode.

• The latest “S” type Central Processing Unit (CPU) is used
in the PCM receiver. It has the highest degree of resistance to
electro-mechanical “noise.”
• A narrow band ceramic filter for high signal selectivity also
assists in rejecting cross modulation from other common radio
frequency difficulties, such as R/C transmitters or local paging
systems.
• The receiver features Direct Servo Control (DSC) for control of surfaces without radio frequency output.
• The Central Processing Unit (CPU) improves signal reception and integrated fail-safe feature.
• The new NER-950S offers the highest resolution available
in any receiver.
• The receiver has low current consumption.
• The receiver features 3-point gold plated connectors for
increased conductivity .
DS8231 Digital
• The DS8231 features wide spaced dual ball bearings
designed to endure the high vibration environments commonly associated with many radio control models.
• A high frequency digital amplifier offers up to 5 times
greater holding torque than a conventional servo
• Super-tight deadband of .06
µs
for superior accuracy
• Up to 5 times more holding torque than a conventional
servo with less than a 10% increase in current drain
• High output F.E.T . transistor driven motor
• High resolution of 5,900 steps per 120°
• 13 bit A/D converter
T o obtain the highest performance levels from your tail rotor/
gyro system, great care and consideration must be taken in the
selection of the servo to be used.
In general, the quicker the transit time and the more accurate the
centering abilities of the servo, the better the gyro will perform.
If a servo with a slow transit time is used (more than .24 sec/60º),
in actuality the gyro system, especially a Piezo unit, may become
too quick for the servo, resulting in a “wag” or “hunting” situation which would require the user to reduce the percentage of
gain to compensate for this deficiency . This reduction in gain
would also reduce the holding power and, therefore, the performance of your gyro system.
The following optional JR servos are recommended specifically
for use on the tail rotor:
The following gyro systems are highly recommended for use
with the
PCM
10X system. Each of these gyros is designed to
make full use of the Code 44 gyro sensitivity adjustment feature
of this system.

Antenna
• The adjustable base can be locked into position by tightening the two screws just to the rear of the antenna ball mount. Do
not over-tighten. This feature allows you to determine the antenna
angle that suits you best and to lock it in place.
• The antenna can be removed and stored in the special compartment in the right side panel of the transmitter. The next time
you fly , simply thread the antenna into the ball mount. It will
automatically assume the previously set angle.
Note: Do not point your antenna directly at your model heli-
copter. The tip of the antenna is the weakest radio frequency
radiator in any radio controlled transmitter. Instead, have the
antenna at about a 20°– 45° angle away from the model.

Control Stick Length Adjustment
The PCM10X allows you to adjust the control sticks’ length.
T o adjust the stick length, use the 2mm Allen wrench (sup-
plied with your
PCM10X transmitter) to unlock the set screw .
Note: T urn the wrench counter clockwise to loosen the screw
and clockwise to tighten it.
Turn the knurled part of the stick counterclockwise to lengthen
and clockwise to shorten.
After the control stick length has been adjusted to suit your
flying style, simply tighten the 2mm set screw .
If you desire longer sticks,
JR has developed a new, thicker
stick (JRPA047) which is approximately one inch longer than the
standard sticks. This stick, crafted from bar stock aluminum, is
available at your local
JR dealer.
An eyelet is provided on the face of the
PCM10X transmitter
which enables you to connect a neck strap (JRPA023). This hook
has been positioned so that your transmitter will have the best
possible balance when you use a neck strap.
Cautionary Note: Please double check to ensure that the neck
strap is securely fastened to the transmitter.
The 10X allows you to individually tailor the tension of each of
your stick control inputs to suit your flying style. The procedure
is as follows:
1. Carefully remove the rear rubber grips. Do this by gently
prying the grip by hand from the case.
2. Carefully remove the lower right-hand rubber plug. (The
upper left rubber plug is used for adjusting Mode 1 transmitters
only.)
3. Using a small Phillips screwdriver, rotate each adjusting
screw clockwise to tighten its respective stick tension(counterclockwise to loosen).
After achieving the desired stick tension, carefully replace the
rubber grips and plugs.

Direct Servo Control (DSC)
For proper DSC hook-up and operation:
1. Leave the transmitter power switch in the “off” position.
The transmitter will not transmit any radio frequency (
RF) in this
position.
2. Plug the
DSC cord (supplied) into the DSC
port in the rear
of the transmitter.
3. The encoder section of the transmitter will now be opera-
tional and the
LCD display will be lit.
4. Plug the other end of the
DSC cord into the receiver charge
receptacle. Turn the switch harness to the “on” position.
Note: When installing the switch hareness charging jack, be
sure to hook the
charging jack r eceptacle
, JRPA024,
securely into
the switch harness charge cor d.
Why you should use the DSC function:
1. The DSC
enables you to check the control surfaces of your
helicopter without drawing the fully operational 200ma from
your transmitter battery pack. Instead, you will only draw
70ma when using the
DSC function.
2. The
DSC function allows you to make final adjustments to
your helicopter without transmitting any radio signals. Therefore,
if another pilot is flying on your frequency , you can still adjust
your helicopter and not interfere with the other pilot’s aircraft.
Note: Under no circumstances should you attempt to fly your
helicopter with the DSC cord plugged in! This feature is for
bench checking your helicopter only.
Frequency Notes
The PCM10X employs a plug-in module system for transmitter
frequency changes. If you wish to change a frequency , you can
simply change the radio frequency (
RF) module, commonly
referred to as either an
RF module or transmitter module. The JR
modules are universal for all of the modular frequency controlled
systems. In other words, if you currently own a modular JR system, you can use the
RF module from your current system with
the new
PCM10X.
The
PCM10X can transmit in either pulse code modulation (PCM
)
or in pulse position modulation (
PPM). Be certain to observe the
following guidelines:
1. Do not operate your transmitter when another transmitter is
using the same frequency , regardless of whether the second
transmitter is
PCM, PPM, AM or FM. You can never operate two
transmitters on the same frequency simultaneously without causing interference to both receivers and crashing both aircraft.
2. For operation of your
PCM10X with additional receivers, you
should refer to the receiver compatibility chart. The chart is
located in Section 8.25 of this manual.
Aircraft Only Frequencies
JR RF modules and receivers are available in 50, 53 and 72 MHz
frequencies in the United States for use with model aircraft.
Employing 72 MHz frequencies does not require a special operator’s license from the Federal Communications Commission
(FCC). However, the 50 and 53 MHz frequencies require that
you carry a T echnician no code II license.
• A chart for all available frequencies is located in Section 14
of this manual.

10X MANUAL Heli
It is extremely important that your radio system be correctly
installed in your model. Here are a few suggestions on the
installation of your
JR equipment:
1. Wrap the receiver in protective foam rubber that is no
less than 3/8 inch thick. Secure the foam to the receiver with
#64 rubber bands. This will protect the receiver in a crash or a
very hard landing.
2. The servos should be mounted using rubber grommets and
brass bushings to isolate them from vibrations. Do not overtighten the mounting screws — this will negate the vibration
absorption effect of the rubber grommets. The diagram at right
will assist you in properly mounting your servo.
The brass bushings are pushed from the bottom up in the rubber
grommets. When the servo screw is tightened securely , this will
provide the proper security as well as the proper vibration isolation for your servo.
3. The servos must be able to move freely over their entire
range of travel. Make sure that the control linkages do not bind
or impede the movement of any of the servos.
4. Mount all switches away from the engine exhaust and
away from any high vibration areas. Make sure the switch operates freely and is able to operate over its full travel.
5. Mount the receiver antenna firmly to the helicopter to
ensure that it will not become entangled in the main and/or tail
rotor blades of your helicopter.

10X MANUAL Heli
A five year lithium battery protects all pre-programmed data
against main transmitter battery failure. The lithium battery also
allows the 10X to retain all pre-programmed data in the event the
transmitter battery pack is removed from the transmitter. Should
the lithium battery fail, the display will indicate
BACK UP ERR
.
and an audible alarm will sound. If this occurs, you will have to
have the lithium battery replaced. All transmitter programs will
return to the factory default settings, and the data you have
entered will be lost and have to be re-programmed. When it
becomes necessary to replace the lithium back-up battery , please
contact Horizon Service Center. Improper removal or replacement can cause extensive damage, and only the Horizon Service
Center is authorized to make this battery change.
Note: If you are flying when the lithium back-up battery fails,
you will not lose control of your aircraft. However, when the
transmitter power is turned off, all the programmed data will be
lost. It is for this reason that we urge you to record all input data
on the data sheet provided at the back of this manual.
If any switches are on that could be dangerous (e.g., Throttle
Hold, Flight Mode-Stunt modes 1–4) when you first power up
your transmitter, an audible alarm will sound. The display shows
you which switches are out of position by flashing the name of
the activated switch as shown below .
When the switches have been returned to their normal or “off”
position, the screen changes to the standard display , and the audible alarm will cease to sound.
As a precautionary measure, we recommend that prior to starting
your model you turn your radio “off” and then return it to the
“on” position. If any of the critical switches are on without your
knowledge, the transmitter will tell you.
Your new PCM10X system is equipped with the new All Servo
Hold function, located to the lower right side of the main screen.
This feature allows you to “hold” the movement of all servos so
that the flight mode switch can be utilized to display trim values
for each of the flight modes, all while your heli’s engine is still
running.
This feature is very helpful because it allows the user to view the
individual flight mode trim values on the main screen without
having to turn off the helicopter’s engine.
The All Servo Hold function also has a special safety feature that
will not allow the servos to be re-activated until the throttle stick
is at the low position and the flight mode switch is in the low
position. A warning will be displayed on the main screen
instructing you to move the throttle stick and flight mode switch
to the correct positions (FM Normal and Low Throttle).

Reversing Switches
This is an electronic means of reversing the throw of a given
(servo) channel. All ten (10) channels of the PCM10X offer
reversible servo direction. This will ease setup during the servo
installation into your helicopter.
Accessing and Utilizing the Servo
Reversing Feature
Prior to accessing the servo reversing feature, determine which
servos’ travel needs to be reversed. T o do so, move the controls
of your
PCM10X and observe the travel direction of each servo.
If the respective servo is not moving properly , i.e., not in accordance with the control input, then reverse its direction.
Upon determining which channels need to be reversed, access
the servo reversing feature by entering Code 11 in the code number access selection or by using the direct mode method.
The screen will appear as follows:
T o reverse the travel direction of any servo (channel), simply
touch the number which correlates to that channel. Note that the
shaded portion of the upper box moves to the opposite position.
This indicates the travel has been reversed.
Upon completing the servo’s travel direction, press
ENTER to exit
this feature and memorize the servo travel direction.
Note: All servo directions are set to their normal throw at the
factory and are set at the default positions (Code 28 or clear).

T ravel Adjust/A TV/End Point Adjust
The purpose of Travel Adjust, also known as adjustable travel
volume (ATV) or end point adjust, is to allow you to adjust the
total travel of a servo in both directions. The 10X offers travel
adjust for all ten (10) channels. The travel adjustment range is
from 0% to 150% and can be adjusted for each direction individually . Use this function to set the maximum control throws that
you’ll use to fly the helicopter. However, make sure that servo
travel is not so great that it causes binding by trying to move the
surface past its physical limitations. A servo that is stalled causes
high current drain and can cause radio drop outs, a condition
where receiver voltage drops below its operational minimum,
causing intermittent loss of control. A strong servo may also
damage control surfaces and linkages if it travels too far.
Accessing and Utilizing the T ravel Adjust/A TV
Feature
T o access the Travel Adjust feature, enter Code 12 in the code
number access selection or use the direct mode method.
The screen will appear as follows:
The 10X has a new feature that makes setting up travel adjust
both quicker and easier. The 10X allows the option of both travel
adjustment directions (up/down, right/left) to be adjusted either
simultaneously or independently . From the factory default settings, the 10X is set to simultaneously adjust both directions
indicated by the shaded area. An S appears in the shaded box at
the top of the screen (see above screen). This is helpful in adjusting the overall rough travel values of the servos. T o independently fine tune travel adjustment in each direction, press the S button at the top of the screen. The shaded area now only covers one
of the values and only that value will be adjusted.
Note: In this mode the shaded box follows the directional
movement of the control. It is this value you will be adjusting.
Press the + key to increase the amount of servo travel and the
- key to shorten the amount of servo throw . If you want to reset
the travel throw to the factory default, 100%, you can either press
the + and - keys simultaneously or press the CL key .
After adjusting the travel volume for all ten (10) channels, press
the ENTER key to exit this function and memorize these values.
Note: Any time you exit the T ravel Adjust screen, the Travel

Dual Rate/Exponential Adjustments
Up to five programmable rates, each with their own exponential
values, are offered on the aileron, elevator and rudder channels
when flight modes are activated. (Three rates are available for
aileron elevator and rudder in normal mode.) In addition, rate
and expo values are independently adjustable in each direction,
allowing you to perfectly tailor the response and feel of your
helicopter. We’ve found this especially beneficial for aerobatics
as the dual rate and expo values to achieve the same response/
feel with up and down elevator can be quite different.
Dual rates offer the ability to adjust the travel of the primary control surfaces (aileron, elevator, rudder) via a switch, thus altering
the aircraft’s response rate so specific maneuvers can be
achieved. Aggressive maneuvers like 3D aerobatics require large
control throws, while slow rolls, rolling circles, etc., require
much smaller control throws to avoid over-sensitivity. Dual rates
allow you to change your aircraft’s response in flight.
Exponential does not affect the overall travel (end points) of the
channel/servo. Exponential affects the rate at which the servo
moves in intermediate positions (less than full travel) and is typically used to desensitize the neutral area such that minor corrections
can be input easily to level the helicopter . When exponential is not
used, the servo response rate is linear . That is, for every incremental
step the control stick moves, the servo also moves in the same
increments. If the stick moves 10%, the servo moves 10%.
When Exponential is activated, a positive (+) Expo value causes
the servo to move less than the stick when the stick is near the
neutral position. For example, the stick may be moved 20% while
the servo moves 10%. As the stick is moved further from center,
the servo movement is increased, and at the extremes of travel,
the % of servo travel is actually higher than the stick travel. The
larger the (+) Expo value selected, the less sensitivity (reduced
servo movement) will occur around neutral, but a greater sensitivity will occur at the extremes of travel.
As mentioned, Expo is typically used to reduce sensitivity
around neutral stick positions while still having high control
authority at the extremes of travel. This provides the pilot with
very smooth, precise control while using relatively large movements with the control sticks. If you’d like to try Expo for the
first time, a value of +20% is a good place to start. This will give
you the feel that Expo offers, but won’t be so different than what
you’ve been flying.
Note: The 10X allows a negative (-) Exponential value to be
programmed. This has the opposite effect as described above in
that (-) Expo values will cause the control response to be greater
(more sensitive) around neutral. Negative Expo values are very
seldom used and should be tried with caution.
Your 10X offers you your choice of five different response
curves for your aileron, elevator and rudder controls. We suggest
that you experiment with the curves, as they can greatly enhance
the performance of your R/C aircraft.
The graphs below are shown to help demonstrate how each of the
response curves differ:
Graph 1 represents the normal, or linear, stick control. The servo
response is equal throughout the stick movement.
Graph 2 represents the normal stick control with the introduction of positive exponential. The response or rate of servo travel
is less at the neutral point and increases as the stick reaches its
travel limits. This type of exponential rate is useful if the controls
are very sensitive around the neutral point.
Note: If negative exponential were used, the response, or
“feel,” of the control would be opposite. The response, or rate, of
servo travel would be greater near the neutral point.
Graph 3 represents the VTR (Variable Trace Rates). W ith the
VTR feature activated, your transmitter operates in the dual rate
mode until it reaches the selected VTR point (50%–90%).
Control then switches to the higher rate.
Graph 4 represents a combination of linear and exponential
rates. Your control functions on a linear curve until it reaches
50% stick travel, where it switches to an exponential curve. In
other words, it is a linear center and a expo curved a the extremes
of travel.
Graph 5 represents an Expo Linear curve. However, travel rates
are exponential around center and then switch to linear after 50%
of stick travel.

Accessing and Utilizing the
Dual Rate/Exponential Feature
T o access the Dual Rate and Exponential features, enter Code 13
in the code number access selection or use the direct mode
method.
Your screen will appear as follows:
Note: Although dual rates and exponential operate in conjunc-
tion with one another, we will cover them separately.
Dual Rates
The adjustable range for each of the dual rate positions is 0-100%.
In normal flight mode, the dual rates used are dependent on the
0 and 1 switch position for each of the applicable channels.
When the stunt modes and the throttle hold switches are activated, the rates are controlled by the auto dual rate function,
Code 23, located in Section 8.8 of this manual.
First, touch the
PAGE
key to call up the desired channel (aileron,
elevator, or rudder) for which you want to adjust the rate.
Select the switch position for which you want to adjust the rate.
Keep in mind that 0 and 1 pertain to the
D/R switches when in the
normal flight mode, while the 2 position may be called up on the
auto dual rate feature.
Next, adjust the rate for the channel and the switch position that
you have previously selected. T o decrease the throw rates, touch
the - key . To increase the throw rate, touch the + key.
Note: It is not possible to increase the throw rate from the
factory default settings. You may observe the servo changes by
moving the respective stick while increasing or decreasing the
values. The control changes accor dingly. To clear the dual rate,
touch the
CL key, or the + and - keys simultaneously.
After the rates have been dialed in to your satisfaction, begin to
adjust the exponential values. Remember that the exponential
values do not change the rates. They only alter the way in which
this travel is reached.
Adjustment of the Exponential Curves
The adjustable range of the exponential curve is ±100% for each
of the positions and the respective channels.
The greater the positive exponential value, the less servo action
or sensitivity you will notice around the neutral setting. The
opposite is also true: The greater the negative value, the more
servo action or sensitivity you will notice at the neutral point.
The following graphs may aid in understanding the exponential curve.
The response or rate of servo
travel is less at the neutral point
and increases as the stick reaches its travel limits. This type of
exponential rate is useful if the
controls are very sensitive
around the neutral point.
The response rate of this servo
is more around neutral and
decreases as the stick reaches its
travel limits. This type of exponential rate is useful if the control is very slow or unresponsive
around the neutral point.
T o adjust the exponential rate use the +, - and
CL keys. The + key
increases the exponential rate, while the - key decreases the
response rate. T o clear the exponential rate, touch the
CL key, or
the + and - keys simultaneously .
VTR: Variable Trace Rate
This feature may be thought of as a double dual rate. The
adjustable range of
VTR is from 50-90% in 10% increments.
When
VTR is active, the servo response remains linear over the
first portion of the dual rate curve and then switches to the higher
rate at the point you have selected.
T o select among the
VTR rates, touch the SEL on the lower por-
tion of the
LCD screen.
As you can see in the graphs at the bottom of the page, over the
first portion of travel the servo response rate is linear, but at the
variable trace rate, it switches to the higher rate of travel.

You also have the choice of either an exponential/linear curve or
linear/exponential. These curves appear as follows:
Up to 50% stick travel around
center at the linear rate, it then
switches to exponential. In
other words, it operates both
ways, linear over the first portion of the curve and with an
exponential rate over the last
portion.
Up to 50% stick travel around
center at the exponential rate, it
then switches to the linear rates.
In other words, it operates both
ways: exponentially over the first
portion of the curve and with a
linear rate over the last portion.
Summary of Exponential Curve Selections
Adjusting Dual Rates and Expo Value Independently
in Each Direction
The 10X allows dual rates and/or Expo values to be independently adjusted in each direction of servo travel. This is extremely
useful in that many aircraft have differing pitch, roll or yaw rates
in each direction, and a different value is needed to achieve the
same response and feel in both directions. It’s typical for an aerobatic aircraft to require slightly more down dual rate and less
Expo value to achieve the same feel for up and down elevator.
T o independently adjust the dual rate or Expo value for each
direction, simply move the appropriate stick in the desired direction, and the shaded box will highlight only the selected direction. Now adjustments can be made to that direction only .
Set Up Tip
Exponential
Many fliers have found that using exponential on fore/aft
and right/left cyclic allows them to input more precisely
minor corrections during hovering, while still allowing
adequate control throw at the end of the stick travel. We
recommend +15% expo on ailerons and elevator as a
good starting point.

Sub-T rim Adjustment
The sub-trim adjustment is a feature that allows you to electronically
fine-tune the centering of your servos. Individually adjustable for all
ten (10) channels with a range of +/-250% in increments of 2%
(+/-30° servo travel), the sub-trims can be set for the same neutral
settings for each model stored in the transmitter’s memory . This
allows the same mechanical trim tab settings between all of the models you control with the same transmitter. You don’t have to make the
precise mechanical adjustments to your aircraft to achieve these
results, as you would normally have to do with a standard transmitter.
Accessing and Utilizing the Sub-T rim
Adjustments
T o access the sub-trim adjustments, enter Code 15 in the code
number access selection or use the direct mode method.
The screen will appear as follows:
This feature enables you to electronically correct for slight mechanical misalignments that previously had to be corrected manually .
Caution: Do not use excessive sub-trim adjustments since it is
possible to overrun your servo’s maximum travel if it is offcenter. Remember that this is a trim convenience feature. It is not
intended to take the place of the proper mechanical trim adjustments that are necessary on any R/C model. Offset servos also
produce a differential throw effect.
For corrections in trim offsets of aileron, elevator, and rudder
channels, refer to Code 82, trim offset adjustment.
Press the + key to increase the amount of offset or press the - key
to decrease (actually increase) the amount of opposite offset. To
reset the sub-trims to the factory default, 0, press the + and - keys

from a previous generation JR 10-channel radio to the 10X, the
sub-trim values of the older 10-channel radio must be doubled
in order to properly match when programmed into the 10X.
Throttle Hold
The Throttle Hold function (when activated) allows you to retain
control of the collective servo, yet leave the throttle servo at a
pre-determined position. This feature is particularly useful for
autorotations. It switches the throttle servo to a preset position
and disconnects it from the control stick, but leaves the collective
pitch control with the stick position.
Accessing and Utilizing
the Throttle Hold Function
T o access the Throttle Hold function, enter Code 16 in the code
number access selection or use the direct mode method. The
screen will appear as follows:
T ouch the
ACT key to activate the throttle hold feature.
The screen will now appear as follows:
If the switch is active (as in the example) and the switch is in the
“off” position, “off” will appear below the throttle hold position.
If the switch has been activated and is in the “on” position, the
“off” indication will not appear .
If the program is returned to the inhibited selection, the values
are retained (for the hold position and automatic throttle cut
options) for the next time Throttle Hold, Code 16, is accessed
within the same model.
T ouch the + or - keys to increase/decrease, respectively, the value
(position) that the throttle servo will assume when it is put into
the throttle hold position.
Hold Position
The adjustable value for the throttle hold position is between 0 to
100 and is pro-rated to the throttle curve value.
The value (position) you program for the hold position is the
position which your throttle servo assumes when the Hold function is activated.
The word “off” may appear below the hold position value if the
throttle hold switch is in the “off” position or if the throttle stick
has not been reduced below the automatic cut position.
Note: The high and low pitch trim levers, if activated in Code
17, Function Select, still affect the high and low pitch curve, even
if the Throttle Hold function is activated.
Auto Cut Setting
The auto cut setting may be easier to think of as an automatic
throttle cut-off point, since this is the function it performs. This
feature allows you to select whatever throttle stick position activates the Throttle Hold function. Although the throttle hold
switch may be active, the throttle servo itself also remains active,
i.e., following the throttle stick movement, until you reach the
auto cut position that you are about to select.
Selecting the Auto Cut Position
This process is a very simple one. Place the throttle stick to the
position for which you desire the throttle hold to become active
and touch the key located below the auto cut. The display now
exhibits the value of the stick position that you have selected.
This value will be between 0–100%
If you want to change the auto cut point after you have already
selected one, touch the
CL key below the auto cut. This inhibits
the previous position. Next, move the throttle stick to the desired
location and press the
STORE key . The new value will be dis-
played at this time.
Most model helicopter pilots select a point very near the lowest
throttle stick position for their auto cut position.
Note: If you opt not to select a point for the auto cut to
engage, the throttle servo immediately assumes its hold position
once the throttle hold switch is activated.

The Throttle Hold Delay function is a new addition to the
PCM10X software. This feature functions as a way to delay or
“Slow” the throttle servo’s movement when switching from
throttle hold back to the previous flight mode.
This feature is very helpful when practicing autorotations as it allows
the autorotation to be aborted if necessary , without the usual harsh
return to full power. In conventional systems, when an autorotation is
aborted, the engine immediately returns to an extremely high throttle
position as indicated by the previous flight mode. This situation causes a very high load to be applied to the main gear and drive train of
the helicopter due to the engine’s immediate return to power , and in
some cases it can damage the main drive gear, or other components
of the helicopter. This sudden return to power can also cause the helicopter to rotate violently due to the immediate return of torque, which
can startle the pilot at the very least.
The Throttle Hold Delay function eliminates all of the previously
mentioned problems by bringing the engine back to full power
smoothly . This feature can be custom tailored to the individual
pilot’s requirements and is adjustable in increments of 1/4 second,1/2 second,3/4 second, and 1 second delay times.
Set Up Tip
Establishing Your Throttle Hold Delay Value
For initial testing of the Throttle Hold Delay function in
flight, it is suggested that you start at the 1/4 second setting for the first flight so you can develop the feel for this
function. Increase the delay time as needed until the
desired delay time is achieved.
Press to select the desired Throttle Hold Delay value:
1/4 second, 1/2 second, 3/4 second, 1 second
Function Select
Function Select allows you to activate/inhibit flight modes 3 and 4
and assign the switch position, to assign the function of the gear
switch (hold, gear, inhibit), to activate the function of the Aux2
switch and to activate/inhibit the low and high pitch trim levers.
This function also allows the user to inhibit the Digital Trim function in Stunt Modes 1–4 if desired.
Accessing and Utilizing the
Function Select Function
T o access the Function Select function, enter Code 17 in the code
number access selection or use the direct mode method.
The screen will appear as follows:
Extra Flight Mode Function
(Flight Mode 3 and 4)
The Extra Flight Mode function allows two additional flight
modes (3 and 4) to be activated and placed on the gear switch or
the aileron dual rate switch.
Touch
SEL located below the flight extra on the left-hand side of
the screen once to activate the Flight Modes 3 and 4 on the gear
switch (gear) and touch
SEL again to activate Flight Modes 3 and
4 on the aileron dual rate switch.
Note: Flight Modes 3 and 4 work in conjunction with the flight
modes N, 1, and 2 switch.
When the flight mode switch is in the Normal (
N) position,
Normal mode is selected regardless of the extra flight mode
switch position. When the flight mode switch is in the #1 or #2
position, the actual flight mode is relative to the position of the
extra flight mode switch. If the extra flight mode switch is on, the
position 1 and 2 on the standard flight mode switch result in
Flight Modes 3 and 4.
Separate throttle curves, pitch curves, stunt trims, tail curves,
programmable mixes, swashplate timing, auto dual rates and
gyro rates are available in Normal, Flight Mode 1, Flight Mode 2,
Flight Mode 3 and Flight Mode 4. See these sections for details.
Gear Switch
Channel 5, gear switch, can be programmed in these different ways:
When the GEAR
appears below GEAR SW on the screen, the gear
two-position switch activates on Channel 5. T ouch
SEL and
HOLD will appear. Now Channel 5 is activated with the throttle
hold switch. T ouch SEL again and INH (inhibit) appears. This
inhibits Channel 5, and Channel 5 is now useful as a Slave channel for programmable mixing in this inhibit position.
AUX2 Switch
Channel 7, Auxilary 2, can be programmed in these different
ways:
When ACT appears below AUX2 SW on the screen, the AUX2
switch on the transmitter activates the function of channel 7.
When INH appears on the screen, Channel 7 is now useful as a
slave channel for programmable mixing in this inhibited position.
Digital Trim Select
The Digital Trim Select function located at the lower right corner
of the screen, allows the user to deactivate the Digital Trim
Levers in Stunt Modes 1–4 and Hold, while retaining the previously established trim values.
