Smart Throttle
The AR10400T, AR14400T and AR20400T receivers throttle port includes Smart
Throttle. When equipped with Smart Throttle the normal servo connector delivers
the throttle signal to the ESC, plus the ESC can send telemetry data like voltage
and current back to the receiver. The AR10400T, AR14400T and AR20400T
receivers throttle port will automatically detect when a Smart Throttle compatible
ESC is plugged in and the throttle port will begin to operate in Smart Throttle
mode.
ESCs with Smart Throttle and IC3
®
and IC5
®
connectors can also pass along
battery data from compatible Spektrum Smart batteries.
If a standard ESC or servo is plugged into the throttle port on the AR10400T,
AR14400T and AR20400T receivers, the throttle port will operate normally
(PWM signal) like any conventional RC system. The AR10400T, AR14400T and
AR20400T receiver is compatible with the Spektrum Avian line of ESCs for Smart
Throttle.
For Smart Throttle to function you must have a Smart Throttle ESC paired with
a Smart Throttle telemetry receiver, and a Spektrum DSMX transmitter with
telemetry. An update for your transmitter may be required for Smart features.
See www.spektrumrc.com to register and update your transmitter.

To access channels above 12, you are required to enable X-Plus mode on your
transmitter. On DX18 transmitters, channels 11 and 12 will be locked at center if
X-Plus mode is not enabled.
To access 14 channel mode, you must select this option in compatible transmit-
ters.
NOTICE: When using X-Plus to get up to 20 channels, Channels 13-20
have 512ms resolution and a variable frame rate. They are intended for
auxilliary functions such as retracts, lights, etc. We do not recommend using
Channels 13-20 for flight control surfaces. Note: If using 14 channel mode
in compatible transmitters, in 14 channel mode, all 14 channels are 22ms
at 2048 resolution and can be used for flight control channels.
Note: Check your transmitter manual or receiver web site for compatibility
for 14 channel mode. 14 Channel mode is accessed through the Frame
Rate menu and will show in compatible transmitters. Transmitters may
need to be updated to add this feature if available.
See your Transmitter manual for more information about X-Plus mode
Getting Started
1. Install the receiver system in your aircraft.
2. Bind the receiver to your transmitter.
3. Complete model setup on your transmitter.
4. Conduct thorough ground testing.
5. Re-bind to set failsafe settings.
6. Range check.
7. Control surface check before flying.
8. Unplug receiver battery(s) at the end of every flying or testing session.
NOTICE: When using Y-harness or servo extensions with Spektrum
equipment, do not use reversing harnesses. Using reversing Y-harnesses or
servo extensions may cause servos to operate erratically or not function at all.

EN

Installation
1. Find a secure mounting location on a mounting tray or bulkhead
2. Self tapping mounting screws are provided to use the integrated mounting
tabs and grommets.
3. We recomend drilling a pilot hole for the mounting screws to prevent the
mounting surface from splitting.
TIP: If the screw is threading into a soft material such as balsawood,
harden the threads with thin CA before final mounting.
4. It is not neccesary to compress the grommets tightly. Use a 2mm hex driver
to install the mounting screws so the grommets are gently compressed.
5. Secure the remote receivers so they are perpendicular from each other and
located away from conductive materials. It is best to locate the remotes in
different parts of the aircraft for best performance.
TIP: If you have telemetry link performance issues, inspect and/or relocate
the SPM4651T remote receiver to optimize performance in your aicraft.
NOTICE: Do not cut the antenna wire or allow it to kink on the SPM4651T
remote receiver. The last 31mm of the wire is the active portion of the
antenna. The coaxial wire leading up to antenna will be damaged if it is cut
or kinked.
6. Mount the soft switch on the side of your aircraft and insert the switch plug
in the port marked SWITCH.*
Soft Switch
*The PowerSafe receiver uses a specific switch. Conventionally wired switches
are not compatible with the PowerSafe receiver.
• The Soft Switch is a failsafe switch, it opens the circuit to power ON the
receiver. If a switch failure occurs during operation, the system will fail to
the ON position.
• The trickle current when the receiver is powered OFF is negligible and
will not affect the charge status during a flying session. However, always
unplug the batteries from the receiver at the end of a flying session.
• Connect the lead labeled Switch into the receivers Switch port. The
second lead labeled LED PWR can be connected to any of the receiver
ports that are powered to provide power to the switches LED which
can be used to see at a glance that the system is powered on from the
switch. The switch LED is optional, if not used simply secure the LED
PWR lead.
NOTICE: Failure to unplug the receiver batteries after a flying session will
result in a trickle current that will slowly drain the receiver battery. An over-
discharged battery should never be recharged.

EN
8
Mounting the Remote Receivers
Orientation of the Remote Receivers
Mount the remote receivers in a location that allows for the best possible
signal reception when the aircraft is in all possible orientations. Three remote
receivers are included with the AR10400T and four are included with the
AR14400T and AR20400T, we recommend having one mounted with the
antennas oriented vertically, one horizontally in-line with the fuselage and one
horizontally perpendicular to the fuselage.
Locating the Remote Receivers
Find locations for the remote receivers as far from each other and metal,
electronics, carbon fiber, batteries or fuel as possible. Mount the remote
receivers securely in your aircraft, and plug them into the receiver ports.
A remote must be connected to remote port A, and at least 2 remotes must
be connected to the receiver for the receiver to connect to the transmitter and
output to the servos.
Greater antenna separation improves path diversity (RF link performance) in
critical environments. Do not extend remote receivers greater than 36" from
the main receiver.
If remote receivers are added to the system or if the remote receiver setup is
changed after initial binding, the system must be re-bound.
At minimum 1 - SPM4651T remote receiver must be installed (one is included
in every receiver) to have full range telemetry.
Battery Requirements
Battery Voltage
Select a battery for your system based on your servo selection. Ensure your
servos are rated to handle the voltage you intend to run. The low voltage
threshold for the receiver is 3.5 volts. We recommend selecting a battery rated
between 6.0 and 10.0 volts to leave a buffer under heavy loads. If input voltage
is above the 10.0 volt threshold the reciever will not connect power to the
servos. LiPo, LiIon, LiFe, NiMH, and NiCAD batteries may be used, but we do
not recommend using 4 cell NiMH or NiCAD batteries.
Voltage Regulators
Regulators may be used to supply power to the receiver. They provide a
consistant voltage supply under varying current loads. If you are using two
batteries with regulators, each battery needs to have its own dedicated
regulator plugged into separate battery ports on the receiver.
When installation is complete, we recommend thoroughly testing the batteries
under load to verify they can sustain the demands, before commiting the
aircraft to flight.

EN
9
Using One Battery
When using one battery it may be plugged into either battery port. If you are
using one battery, secure the unused battery input connector. A single blue LED
will remain illuminated when the receiver is powered by one battery.
Using Two Batteries
The PowerSafe receivers have a redundant dual battery system, each pack
functions independently and is isolated from the other. If one pack should fail
for any reason (open circuit, short-circuit, or become discharged) the other
battery will provide power to operate the system. When using dual batteries, it’s
important both batteries are the same voltage, capacity, age, and condition.
It is normal for only one blue LED (Batt 1 or Batt 2) to be illuminated when the
system is not under a heavy current load, depending on which pack is providing
more power. You may see a difference in the capacity put back in during
subsequent charging. Generally the difference is negligible, less than 10%.
Battery Capacity
Select batteries with more than adequate capacity to provide the necessary
flight time. To leave a buffer, prevent dropping the batteries below 40% of their
rated capacity during use.
Installing the Batteries
Spektrum batteries are pre-wired with EC3™or IC3™connectors and plug
directly in. Two IC3 battery connectors are included which you can solder to
your battery or regulator as neccessry to complete the connection. Mount the
batteries securely and protected from vibration. Connect the battery(s) to the
PowerSafe receiver when you are ready to fly, and unplug at the end of your
flying session.
Binding
The AR10400T, AR14400T and AR20400T PowerSafe receivers must be
bound to the transmitter before they will operate. Binding is the process of
linking the transmitter to the receiver, and defines SmartSafe™ settings. The
binding and SmartSafe process may be completed with the bind plug or the
bind button.
1. Connect the remote receivers and any telemetry sensors to the main
receiver. At least 2 remotes must be connected, and 1 must be connected
to port A.
2. Bind the transmitter to the receiver with low throttle.
3. Complete your model setup and configuration on your transmitter and
conduct a thorough ground test of all functions.
4. Before flying, re-bind the transmitter and receiver to set the SmartSafe in
the desired positions.

EN
10
Failsafe
The AR10400T, AR14400T and AR20400T PowerSafe receivers have three
failsafe features: Pre-Connect Failsafe, Preset Failsafe and SmartSafe™.
Pre-Connect Failsafe: Prevents a servo signal from being generated before
the receiver connects to a transmitter. It is not affected by failsafe bind settings.
If the receiver is powered ON with no connection, it will remain in standby
mode with no output pulses to the servos, until a bound transmitter connects.
Failsafe positions are set through forward programming. In the unlikely event
that the radio link is lost during use, the receiver will drive all channels to their
pre-programmed failsafe positions. The blue battery LEDs remain illuminated in
failsafe modes, but the orange LEDs on the main and remote receivers will not
be illuminated when a transmitter is not connected.
Preset Failsafe: With preset failsafe, you can set the specific control surface
positions you want to use if the signal is lost. When the receiver detects the
signal from the transmitter, normal aircraft operation resumes.
Only available through Forward Programming
Testing Failsafe: Secure the aircraft on the ground and remove the propeller.
Test Failsafe settings by turning the transmitter RF output off and noting how
the receiver drives the control surfaces.
Receiver Power Only
• If the receiver is turned when no transmitter signal is present, the throttle
channel will not have a control signal to avoid operating or arming the
electronic speed control.
• All other channels have no output until the receiver has linked to the
transmitter.
Forward Programming
Verify your transmitter is updated your transmitter to the latest Spektrum
AirWareTM software to take advantage of Forward Programming. See your
transmitter manual for updating instructions.
In your transmitter menu select Forward Programming ->
Other Settings ->
• Select Failsafe -> Select each channel and assign it to Preset or Hold Last.
When you select a different channel for Output, a new group of settings
appears. Capture Failsafe Postions ->
Hold the control sticks in the desired failsafe positions and select Apply.
Channel selections must be individually set in Forward Programming to
apply the preset positions or each channel will default to Hold Last. The
value captured will be reflected in the position shown for each channel.
• Initiate Receiver Bind Mode
Gives you the option of putting the receiver into Bind Mode from this menu.

EN
11
• Frame Rate
Gives you the option of adjusting the update rate from the receiver to the
servos (this does not change the frame rate from the transmitter to the
receiver.) When set to INH, the default frame rate from the transmitter will
be the servo update rate. Additional setting options are 5.5ms, 11ms, and
22ms. Some servos cannot handle fast update rates such as old analog
servos. The update rate can be selected for each output allowing different
settings per output channel allowing for high speed update rates to servos
that can handle the faster frame rates and lower update rates to servos that
cannot handle fast frame rates.
In Forward Programming -> PowerSafe Telemetry ->
Dual Battery Capacity Monitoring
The PowerSafe receivers feature dual battery capacity monitoring through
telemetry when used with Spektrum AirWare™ transmitters. Activate the
Auto Config function on the telemetry page in your transmitter to display the
capacity consumed by the receiver. The capacity used is stored flight to flight
and adds until reset. The capacity can be automatically reset when the battery
is charged, allowing easy battery capacity monitoring.
Automatic Reset
With automatic Reset you can select inhibit or active. When set to inhibit you
must manually reset the capacity used after charging the battery/ies. When
set to active the receiver will detect when the battery voltage has raised
sufficiently after a battery charge and automatically reset the capacity. The
pack voltage must drop sufficiently for automatic reset to function, typically a
couple flights are enough.
Capture Charged Voltage
When this is selected the receiver will store the current voltage as the fully
charged voltage of your battery/ies connected. Just below the Capture Charged
Voltage button/bar are the charged voltage settings currently saved, if you
press capture charged voltage just after a charge, these values will show the
set points saved. These must be set for the receiver to perform an automatic
reset if active.
12V Servo Bus
Activate this if using 12V servos and 12V battery pack/s, this will allow the
receiver to operate at 12V and disable regenerative servo support. With this
active the servo bus will not activate if the voltage exceeds 13V. Note that
any servos connected to the servo bus must be capable of handling 12V if
using 12V battery/ies and this function is active. If not using a 12V battery
system and 12V servos, leave this setting set to inhibit. When set to inhibit,
the receiver will not power the servo bus if the voltage supplied is over 10V
and the regenerative servo support will be active. Warning: If 12V Servo Bus is
active, standard servos and other devices not able to handle 12V may burn out
or otherwise be damaged.

EN
12
Reset Capacity
From the Forward Programming->PowerSafe Telemetry menu, press NEXT to
see the manual reset capacity button. Press this to reset the stored capacity
used manually. Use this when not using Automatic Reset after a charge to
reset your battery capacity used. In addition to being able to reset the capacity
through forward programming, you can also reset the capacity by pressing the
bind button while the receiver is on and connected to a transmitter.
SmartSafe Options
Preset Failsafe: If signal loss occurs, the receiver will move all the channels
to their failsafe positions.
SmartSafe +Hold Last: If signal loss occurs, SmartSafe™ technology
moves the throttle channel to its preset failsafe position, and all other channels
hold their last position. When the receiver detects a signal from the transmitter,
normal aircraft operation resumes.
If at any time you turn on the system and it fails to connect, verify the correct
model memory is selected in the transmitter.
After Connection
When the transmitter and receiver are connected, the orange LEDs on the
main receiver unit and remote receivers will remain illuminated. If for any
reason a failsafe is triggered, the system will immediately regain control upon
the connection being restored.
Flight Log
Flight Log data can help you optimize the control link for your aircraft. Flight
Log data is displayed on telemetry capable Spektrum transmitters.
Using the Flight Log
A- Fades on remote receiver con-
nected to A port.
B- Fades on remote receiver
connected to B port
L - Fades on remote receiver
connected to L port
R- Fades on remote receiver
connected to R port
F - Frame losses H- Holds
Fades
Represents the loss of one bit of information on one receiver. Fades are
used to evaluate the performance of each individual receiver. If any single
receiver displays higher fade values it should be inspected and the antenna
repositioned to optimize the RF link.
Frame Loss
A frame loss occurs when one complete data packet is missed. A single
frame loss does not represent a loss of control, but frame losses should be
monitored. In the air it's normal to experience as many as 100 frame losses
per minute of flight. On the ground the number of frame losses will be higher
because the signal is hampered by earth and moisture.

EN
13
Hold
A Hold occurs when 45 consecutive frame losses occur. This takes about one
second, and in this event the receiver moves the channel outputs to the failsafe
settings. If a hold ever occurs, it’s important to re-evaluate the system and
check every component. If your system displays a hold taking place, diagnose
the cause and resolve the issue before flying again.
It is normal to see a hold logged if you power OFF your transmitter and back ON.
IMPORTANT: The Spektrum Flight Log (SPM9540) is not compatible with
the PowerSafe receivers.
Micro SD Card
When a micro SD card is inserted into the receiver, during operation, flight
information will be logged onto a file on the card including flight log data,
battery status and other telemetry data stored over time. If not deleted, older
data logs recorded will be deleted, keeping the most recent logs. This can be
a handy tool to review flight data over time which can be helpful for diagnosis
of performance.
Micro USB Updating
The PowerSafe receivers feature a Micro USB connector which can be used
with a micro USB cable (available separately) to update both the main receiver
firmware as well as any connected remotes making it very easy to update the
receiver and any attached remote receivers. Simply connect the receiver with a
micro USB cable and use the Spektrum PC programmer to update the receiver
and any attached remote receivers. Note: The Spektrum Programmer USB cable
must be disconnected from the computer for the micro USB connection to work.
Please make sure to use the Spektrum Programmer application v3.6 or newer.
Status LED
The Status LED will give information about the status of the receiver and give
warning codes if there is an issue or condition detected: Differentiate codes/
modes by flashing count. Note: Check the website for any future updates.
• White Blinking/Breathing - Initializing, not ready to fly
• Red - Failure, failure where you can't fly. Check power or RF.
• 2 blinks - 3S Power Detected/Protection engaged
• 1 blink - No remote detected in port A or not enough remotes detected,
need at least 2 remotes connected and one must be in port A.
• Solid Blue - Ready (w/ recording). Ready to fly recording w/ SD
• Solid Green - Ready (w/o recording). Ready to fly, not recording to an
SD card.

EN
14
Range Testing
Before each flying session, and especially with a new model, it’s important to
perform a range check. All Spektrum aircraft transmitters incorporate a range
testing system, which reduces the output power to allow a range check.
1. With the model resting on the ground, stand approximately 100 feet (30
meters) away from the model.
2. Face the model with the transmitter in your normal flying position and put
your transmitter into range test mode.
3. You should have total control of the model in range test mode at 100 feet.
4. If control issues exist, call Horizon Product Support for further assistance.
Advanced Range Testing
The Standard Range Testing procedure is recommended for most sport aircraft.
For sophisticated aircraft that contain significant amounts of conductive
materials (e.g. turbine powered jets, scale aircraft with matalized finishes,
aircraft with carbon fuselages, etc.), the following advanced range check will
confirm that all receivers in the system are operating optimally as installed.
This advanced range check allows the RF performance of each receiver to
be evaluated independantly. A telemetry equipped Spektrum Transmitter is
required for the advanced range test.
1. Stand approximately 100 feet away from the model.
2. Face the model with the transmitter in your normal flying position and put
your transmitter into range test mode.
3. Have a helper position the model in various orientations (nose up, nose
down, nose toward the transmitter, nose away from the transmitter, etc.).
4. Observe the telemetry on your transmitter. Note any orientations that cause
higher fades or frame loss values. Perform this step for at least one minute.
5. Re-position any remote receivers showing higher fades as necessary.
6. Re-test to verify satisfactory results.
7. Repeat as neccesary.
After one minute, advanced testing should yield:
H- 0 holds
F- less than 10 frame losses
A, B, R, L - Fades will typically be less than 100. It’s important to compare the
relative frame losses. If a particular receiver has a significantly higher frame
loss value (2 to 3X) then the test should be redone. If the same results occur,
move the offending receiver to a different location.
TIP: Use the fade values for any SPM4651T remote receivers to investigate the
performance of the telemetry link.

EN
15
Dual Battery Capacity Monitoring
The PowerSafe receivers feature dual battery capacity monitoring through
telemetry when used with Spektrum AirWare™transmitters. Activate the
Auto Config function on the telemetry page in your transmitter to display the
capacity consumed by the receiver. The capacity used is stored flight to flight
and adds until reset. The capacity can be reset when the battery is charged,
allowing easy battery capacity monitoring.
To reset the capacity used:
1. Power on the transmitter and receiver and allow the receiver to connect to
the transmitter.
2. Once connected to the transmitter, either press the bind button on the
receiver or connect a bind plug to the bind port.
3. Capacity used will now be reset.
NOTICE: The capacity will only reset if the transmitter and receiver are
connected before pressing the Bind button or connecting a bind plug. If the
receiver is not connected, capacity used will not be reset, and the receiver
may enter bind mode, indicated by the flashing orange LEDs.
The SPM9604 Receiver sensor is not compatible with PowerSafe receivers
because its function is already built into the receiver.
For information on Spektrum Telemetry Sensors visit:
http://www.spektrumrc.com
Telemetry
The Spektrum AR10400T, AR14400T and AR20400T PowerSafe telemetry
receivers features 4 integrated telemetry ports that are compatible with
Spektrum telemetry capable transmitters.
• No telemetry module required. Telemetry is built into the receiver.
• No sensor is required to receive Flight Log or receiver pack voltage
directly on any telemetry capable Spektrum transmitter.
IMPORTANT: The SPM4651T must be connected and operating in order for
the receiver to transmit Telemetry at full range.
IMPORTANT: Additional SPM4651T remotes can be used to offer redundant
full range telemetry (system will use the strongest link to transmit data) but 1
is required for full range telemetry and is included.
• The PowerSafe telemetry receivers include the SPMA9570A Aircraft
Telemetry Flight Pack Voltage Sensor which is rated up to 60v (14s LiPo)
input.
1. Plug the Aircraft Telemetry Flight Pack Voltage Sensor into the VOLT
Telemetry Port on the PowerSafe Receivers.
2. Splice the other end into the flight battery pack noting polarity. If
you are powering the receiver through a regulator you may need
to disconnect the negative (black) lead for the voltage sensor to
operate reliably.
