SPEKTRUM DX3R USER GUIDE
Spektrum’s DX3R was designed by top level racers
to be the ultimate uncompromising racing radio.
Featuring DSM2™ 2.4GHz technology, the DX3R
offers the fastest possible response rate that’s up to
four times faster than conventional 75 and 27MHz
radio systems. Sophisticated software combined with
an easy-to-use one-touch rolling selector makes
programming quick and easy. User-programmable
switches and buttons allow functions like throttle trim,
steering rate, auxiliary channel functions, brakes,
timers, steering rate override, and even throttle and
steering exponential adjustments to be assigned to
any of six programmable switch/button positions.
Plus the DX3R can easily be converted for right- or
left-handed drivers.
Spektrum™ technology offers a bulletproof radio
link that’s immune to internal (noisy motors/ESC’s,
etc.) and external interfering sources. No longer
will you have to wait for a frequency or worry about
someone else being on the same channel. With
Spektrum, when you’re ready to race there’s nothing
stopping you!
SPEKTRUM DX3R USER GUIDE

ModelMatch/Binding
The DX3R features patent pending ModelMatch™.
ModelMatch prevents a model from being operated
using the wrong model memory. If the wrong model
memory is selected, the receiver simply won’t respond
to the transmitter preventing driving the car using the
wrong model memory.
It’s necessary to program the receiver to a specific
model memory (called binding) so that the receiver
will only recognize and respond to that specific model
memory. See pages 22–23 for specific details on
Binding and ModelMatch.

Installing the Batteries
The transmitter requires 4 AA batteries. Brand name
alkaline batteries provide over 15 hours of run time.
Many racers prefer alkaline batteries over rechargeable
batteries, finding it more convenient to simply replace
the batteries when depleted rather than taking the time
to recharge.
Optional NiMH 1.2-volt AA rechargeable batteries
(SPM9525) can also be used. A charge jack located
below the on/off switch is provided for convenient
recharging with Spektrum’s charger SPM9526.
Remove the battery door and install 4 AA batteries,
noting that the polarity of each corresponds with
the diagram in the battery holder. Replace the
battery door.
Charging
Charger Pigtail for Transmitter
BLACK TO POSITIVE
A charging jack is located just below the on/off
switch. If rechargeable batteries are used, they can
be conveniently charged without removing them from
the transmitter using the charge jack. Use Spektrum’s
charger (SPM9526) to charge rechargeable batteries
in the DX3R.
IMPORTANT: All Spektrum charge jacks are center
pin negative. This is the opposite of many chargers.
Before using a charger, make sure the connector
is center pin negative. This can be done using a
voltmeter. Also, unlike conventional radio systems that
use eight cells to power the transmitter, the DX3R uses
four cells. This is due to the electronics being more
efficient. When charging, be sure to use a charger
designed for four cells (4.8-volt battery pack). Many
racers simply make a harness and use the same
charger used to charge their car packs but turn the
current rate down to 1 to 2 amps.
WARNING: Charge only rechargeable batteries.
Non-rechargeable batteries may burst causing injury
to persons and/or damage to property, and they may
cause fire. Dry location use only.

functions including:
SPEKTRUM DX3R USER GUIDE
In order to operate, the receiver must be bound to the
transmitter. Binding is the process of teaching the
receiver the specific transmitter’s code called GUID
(Globally Unique Identifier). When a receiver is bound
to a transmitter/model memory, the receiver will only
respond to that specific transmitter/model memory
(see ModelMatch).
SPEKTRUM DX3R USER GUIDE
ModelMatch
The DX3R features patent pending ModelMatch
technology that prevents operating a model using the
wrong model memory. During the binding process,
the receiver actually stores the code that is assigned
to the specific model that is currently selected in the
transmitter. For example: if the model that is selected
in the transmitter is model #3, when a receiver is
bound to that transmitter, the receiver will only operate
when model #3 is selected. If another model memory
is selected (model #5 for example) the receiver will
not connect. If model #3 is again selected in the
transmitter, the receiver bound to model #3 will
connect. ModelMatch prevents operating a model
using the wrong model memory.
Failsafe
Failsafe positions are also set during binding. In the
unlikely event that the radio link is lost during use, the
receiver will drive the servos to their preprogrammed
failsafe positions (normally full brakes and straight
steering). If the receiver is turned on prior to turning
on the transmitter, the receiver will enter the failsafe
mode, driving the servos to their preset failsafe
positions. When the transmitter is turned on, normal
control is resumed. Failsafe servo positions are set
during binding (see binding a receiver below).
Calibration
The DX3R can be recalibrated to ensure the
potentiometers exactly correlate with the software
providing the ultimate in accuracy. Instructions on
calibrating the radio are on page 26; however, note
that if calibration is not properly done the radio will
not function. If after calibration the steering or throttle
does not function properly (the travel is reduced or
no servo travel) it will be necessary to recalibrate the
transmitter.

Binding a Receiver
Note: The SR3000HRS (model # SPM1202)
receiver is designed to be used with Spektrum’s
Futaba HRS compatible module system only and
is not compatible with the DX3R.
then the transmitter will beep, indicating the process is
complete. The LED on the receiver should now be solid,
indicating a successful bind has taken place.
Note: Marine compatible DX3R transmitters can
be identified by the following logo located on the
back of the transmitter.
8.Remove the bind plug and store it in a
convenient place.
Note: The only time it’s necessary to do a rebind
is if different failsafe positions are desired or if
the receiver is to be bound to a different model
memory.
Note: The SR3100 operates in DSM2 mode and
is compatible with transmitters that utilize DSM2
protocol.
Note: Some Spektrum receivers like the SR3000
use a bind button rather than a bind plug. The
binding process is the same with this receiver;
however, instead of inserting the plug before
powering up the receiver, press and hold the
bind button while powering up the receiver to
enter bind mode.
1.With the receiver off, insert the bind plug into the Batt/
Bind port in the receiver.

Plug the voltmeter into an open channel port in the
receiver and with the system on, load the servos
(apply pressure with your hand) while monitoring
the voltage at the receiver. The voltage should remain
above 4.8 volts even when all servos are loaded.
For gas vehicles, tap and twist the Rx battery pack
while watching the voltmeter. Some battery packs
have poorly welded tabs that give only intermittent
power. Such a defect will show up during shock
and vibration, so this test will verify that the battery
construction is good.

If a questionable power system is being used (e.g.
small or old battery, ESC that may not have a BEC
that will support the servo’s current draw, etc.), it is
recommended that a voltmeter be used to perform the
following test.
Receiver Connection and
Installation
Receiver Compatibility
The DX3R features DSM2 technology but is also
compatible with Spektrum DSM surface receivers and
Spektrum Marine receivers. When the fastest response
rate is desired, using the system with a DSM2 receiver
like the SR3100 is recommended as this combination
gives the lowest possible latency/quickest response
rate. During the binding process the transmitter
actually “learns” the receiver type (DSM, DSM2 or
Marine) and configures itself to transmit that protocol.
All Spektrum receivers have a minimum operational
voltage of 3.5 volts. If the voltage drops below 3.5
volts, the system will cease control until power is
regained.

2.Power up the receiver. If using an electronic speed
controller the lead should be plugged into the throttle

is used, plug the battery lead into any open port noting
the polarity.
• The ESC’s capability to deliver current to the receiver and
servos in electric vehicles
• The switch harness, battery leads, servo leads, regulators
etc.
Receiver Power System
Requirements
Your system’s range can vary greatly due to your
installation and the environment. In most cases you
should be able to have full control of your vehicle to
the limits of sight (about 300 ft with a 1/10-scale car).
If range issues exist your installation can be optimized
by extending the receiver’s antenna as vertically as
possible locating it as high in the vehicle as practical
and also by routing the antenna away from any
onboard electronics.
Inadequate or intermittent power to the receiver that
is unable to provide the necessary minimum voltage
during operation is the number one cause of control
failures with Spektrum systems. Some of the power
system components that affect the ability to properly
deliver adequate power include:
• Receiver battery pack (number of cells, battery
construction quality, connector and state of charge)

Programming is very intuitive and always starts
with a press, then a roll, then a press, roll and
so on. Most find that within a few minutes they’re able
to easily program their car without reading
the instructions. However, to realize the full benefit
of the programming, it’s recommended that the
manual be read.
Most racers find it’s most convenient to use their
thumb when making programming changes, as
this allows for one-handed programming, even
allowing the car to be run in one hand while making
programming adjustments in the other.

Steering rate (also known as dual rate) allows on-thefly steering travel adjustments to be made using any of
the programmable grip trimmers (A,B,C,D, or E). The
Steering Rate screen also offers a Steering override
function that allows a second steering rate (normally
100%) to be accessed at the touch of a button or
trimmer. This is especially helpful for oval racers
that program minimal steering throw to desensitize
steering during racing but require maximum steering
angle to drive out of a crash or get turned around on
the track. The user name, model number and model
name are also displayed in this screen.
Note: An adjustable S/R rate can be assigned
to any of the trimmers (A,B,C,D and E) and is
defaulted to trimmer D. This trimmer works in
unison with the S/R Rate screen and the value
can be adjusted from either the screen or from
the programmable trimmer. If it’s desired to
not have an on-the-fly adjustable Steering Rate
the S/R trimmer can be inhibited. See System
function under switch selection on page 29 for
more details.
Note: In order for the S/R Override to operate
it must be assigned to a switch or trimmer. The
default position for this function is inhibited. To

Exponential is used to affect the response rate
of the steering, throttle and/or brake. Typically positive
Exponential is used for steering, reducing steering
sensitivity around neutral and making it easier to
drive the car at high speeds in a straight line. But
exponential still allows for the maximum turning
radius.
The DX3R’s Exponential function (Expo for short)
allows independent Expo values in each direction
of all three channels (steering, throttle and
auxiliary). A graphic illustration displays the effect
of exponential adjustment.
To access the
Exponential function
From the List screen rotate the roller to highlight the
Exponential function.

Rotate the roller to highlight the values at the
bottom of the screen; then press the roller to
select the values.
Rotating the roller will now adjust both the right and
left values simultaneously. To adjust the right or left
Expo values independently, move the corresponding
channel’s wheel, throttle stick or trigger the trimmer
that the Aux channel is assigned to, and that value
alone will be highlighted. For example turning the
steering wheel to the right will highlight the right value
only and subsequent adjustment will affect the right
travel only.
Note: Positive and negative Expo values are
available. A positive Expo value results in the
center being less sensitive (desirable most of
the time) while a negative value increases the
sensitivity around center (normally not used).
Note: The DX3R features “sticky gooey.”
When the corresponding channel is moved
in the desired direction (as illustrated above)
and released, the value on that side remains
highlighted. Moving the channel in the opposite
direction will then highlight the opposite value
direction. This allows convenient independent
exponential adjustments without having to hold
the wheel or stick in the desired position. To
highlight both values again after moving the
wheel in one direction, simply press the roller
once with the trigger centered and both values
will be highlighted.

The Sub Trim function is normally used to correct for
minor angular inaccuracies that occur when placing
the servo horn on the servo. In many cases, the servo
horn is not exactly perpendicular to the servo (or in
the exact optimum desired position). Minor sub trim
values can be used to correct this offset inaccuracy.
However, it’s important to understand that large sub
trim values can limit the total throw of the servo
in that direction so small sub-trim values only are
recommended.

The DX3R offers three types of timers.
Internal timer
Automatically records the time that the transmitter is
turned on. Timer A is defaulted to the internal timer.
Up timer
The Up Timer is triggered via a selectable button/
switch and counts up from 00:00 seconds, functioning
as a stopwatch. It is useful for timing a fuel run
to determine fuel mileage/pit stop strategy or, for
electrics, to time the run time of a pack to determine
gear ratio and setup information. To pause the
Up timer, press the button/switch that the timer is
programmed to. To reset the UP timer to 00:00, press
and hold the programmed button for more than three
seconds.
Can be programmed for up to 99 minutes and 99
seconds in one-second increments. Normally this
timer is programmed for the length of the race with
electrics and is defaulted to 5:00 minutes, or the
duration of the fuel tank in gas, warning the driver that
it’s time to pit and refuel. The Down timer is started
via a selectable programmable switch. When the down
timer expires, an alarm will sound and the timer will
begin to count up. To pause the Down timer, press
the button/switch that the timer is programmed to.
To reset the Down timer to its preprogrammed value,
press and hold the programmed button for more than
three seconds. Timer B is defaulted to the Down timer,
the time is defaulted to 5:00 minutes and button F is
defaulted to actuate the down timer.
Two of the three timers can be selected and displayed
on the main screen. The user name, model number

BIND
Failsafe
The DX3R features patent pending ModelMatch
technology that prevents operating a model using the
wrong model memory. During the binding process,
the receiver actually stores the code that is assigned
to the specific model that is currently selected in the
transmitter. For example: if the model that is selected
in the transmitter is model #3, when a receiver is
bound to that transmitter, the receiver will only operate
when model #3 is selected. If another model memory
is selected (model #5 for example) the receiver will
not connect. If model three is again selected in the
transmitter, the receiver bound to model #3 will
connect. ModelMatch prevents operating a model
using the wrong model memory.

Failsafe positions are also set during binding. In the
unlikely event that the radio link is lost during use, the
receiver will drive the servos to their preprogrammed
failsafe positions (normally full brakes and straight
steering). If the receiver is turned on prior to turning
on the transmitter, the receiver will enter the failsafe
mode, driving the servos to their preset failsafe
positions. When the transmitter is turned on, normal
control is resumed. Failsafe servo positions are set
during binding (see Bind on the previous page).
BIND
Binding a Receiver
Binding is the process of teaching the receiver the
specific transmitter’s code called GUID (Globally
Unique Identifier) and storing failsafe values. When a
receiver is bound to a transmitter/model memory, the
receiver will only respond to that specific transmitter/
model memory (see ModelMatch below). It’s also
important to understand that during the binding
process the transmitter is learning the type of receiver
that it’s being bound to, and the transmitter configures
itself to transmit in DSM or DSM2 protocol depending
on the type of receiver that it’s being bound to. Note
that the DX3R stores this information for each model
memory and recalls the proper protocol when that
model is selected. See ModelMatch below.
Note: If a receiver is not bound to a specific
model memory, it will not operate.
6.Rotate the roller to highlight BIND.
Note: The SR3100 operates in DSM2 mode and
is compatible with transmitters that utilize DSM2
protocol.
1.With the receiver off insert the bind plug into the Batt/
Bind port in the receiver.
2. Power up the receiver. If using an electronic speed
controller the lead should be plugged into the throttle
port and the switch turned on. If a receiver battery pack
is used, plug the battery lead into any open port noting
the polarity.
3.Turn on the transmitter and make sure the transmitter is
in the desired model number that you intend to use.
4.Press the rolling selector to access the List screen.

7.With the steering wheel, throttle stick and Aux
channel (if applicable) in the desired preset failsafe
positions, press the roller to initiate the bind process
and to store the failsafe positions. BIND will flash for
a few seconds; then the transmitter will beep, indicating
the process is complete. The LED on the receiver should
now be solid, indicating a successful bind has taken
place.
8.Remove the bind plug and store it in a
convenient place.
Note: The only time it’s necessary to do a rebind
is when different failsafe positions are desired,
or if the receiver is to be bound to a different
model memory.
Note: Some Spektrum receivers, like the
SR3000, use a bind button rather than a bind
plug. The binding process is the same with this
receiver. However, instead of inserting the plug
before powering up the receiver, press and hold
the bind button while powering up the receiver
to enter the bind mode.

General Notes
Radio controlled models are a great source of
pleasure. Unfortunately, they can also pose a potential
hazard if not operated and maintained properly.
It is imperative to install your radio control system
correctly. Additionally, your level of operating
competency must be high enough to ensure you are
able to control your model under all conditions. If you
are a newcomer to radio controlled models, please
seek help from an experienced modeler or your local
hobby shop.
Safety Points to Obey for Modelers
• Ensure your batteries (both transmitter and receiver)
have been properly charged for your model.
• Keep track of the time the system is turned on so you
will know how long you can safely operate your DX3R.
• Check all servos and their connections prior to
each run.
• Do not operate your model near spectators, parking
areas or any other area that could result in injury to
people or damage of property.
• Do not operate your model during adverse weather
conditions. Poor visibility can cause disorientation and
loss of control of your model.
• 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 the operation
of your model you observe any erratic or abnormal
operation, immediately stop operation of your model
until the cause of the problem has been ascertained
and corrected. Safety can never be taken lightly.

Tips on Using Spektrum 2.4GHz
While your DSM equipped 2.4GHz system is intuitive
to operate, functioning nearly identically to 27
and 75MHz systems, following are a few common
questions from customers.
1. Q: Which do I turn on first, the transmitter or the
receiver?
A : It doesn’t matter, although it is suggested to
turn the transmitter on first. If the receiver is turned
on first, all channels will be driven to the failsafe
position set during binding. When the transmitter
is then turned on, the transmitter scans the 2.4GHz
band and acquires an open channel. Then the
receiver that was previously bound to the transmitter
scans the band and finds the GUID (Globally Unique
Identifier code) stored during binding. The system
then connects and operates normally.
If the transmitter is turned on first, the transmitter
scans the 2.4GHz band and acquires an open
channel. When the receiver is turned on, the receiver
scans the 2.4GHz band looking for the previously
stored GUID. When it locates the specific GUID
code and confirms uncorrupted repeatable packet
information, the system connects and normal
operation takes place. Typically this takes 2 to 6
seconds.
3. Q: I’ve heard that the DSM system is less tolerant of
low voltage. Is this correct?
A : All Spektrum surface receivers have an
operational voltage range of 3.5 to 9.6 volts. With
most systems this is not a problem as in fact most
servos cease to operate at around 3.8 volts. When
using multiple high-current draw servos with a
single or inadequate battery/power source, heavy
momentary loads can cause the voltage to dip below
this 3.5-volt threshold, causing the entire system
(servos and receiver) to brown out.
4. Q: Sometimes my receiver loses its bind and won’t
connect requiring rebinding. What happens if the
bind is lost during use?
A : The receiver will never lose its bind unless it’s
instructed to. It’s important to understand that during
the binding process the receiver not only learns the
GUID (code) of the transmitter but the transmitter
learns and stores the type of receiver that it’s bound
to. If the system fails to connect, more than likely the
transmitter is near conductive material (transmitter
case, truck bed, etc.) and the reflected 2.4GHz
energy is preventing the system from connecting.
(See tip #2)
2. Q: Sometimes the system takes longer to connect
and sometimes it doesn’t connect at all?
Warning
An RC model is not a toy! If misused, it can cause
serious bodily harm and damage to property. Operate
only in open areas, following all instructions included

THAT THEY ALONE HAVE DETERMINED THAT
THE PRODUCT WILL SUITABLY MEET THE
REQUIREMENTS OF THE PURCHASER’S INTENDED
USE.
A : In order for the system to connect (after the
receiver is bound) the receiver must receive a
large number of consecutive uninterrupted perfect
packets from the transmitter in order to connect.
This process is purposely critical of the environment
ensuring that it’s safe to operate when the system
does connect. If the transmitter is too close to the
receiver (less than 4 ft) or if the transmitter is located
near metal objects (metal TX case, the bed of a truck,
the top of a metal work bench, etc.) connection
will take longer and in some cases connection
will not occur as the system is receiving reflected
2.4GHz energy from itself and is interpreting this
as unfriendly noise. Moving the system away from
metal objects or moving the transmitter away from
the receiver and powering the system again will
cause a connection to occur. This only happens
during the initial connection. Once connected the
system is locked in and should a loss of signal
occur (failsafe) the system connects immediately
(4ms) when signal is regained.
