Spektrum’s DX3R was designed by top level
racers to be the ultimate uncompromising racing
radio. Featuring DSM2™ next generation 2.4GHz
technology, the DX3R offers the fastest possible
response rate that’s up to 4 times faster than
conventional 75 and 27MHz radio systems.
Sophisticated software combined with an easy­to-use one-touch roller 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 left­handed 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!

ModelMaTCh/bIndIng

The DX3R features ModelMatch™ (patent pending).
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 and 23 for specific
details on Binding and ModelMatch.

The transmitter requires 4 AA batteries: brand
name alkaline AA’s providing 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 NiCd or NiMH 1.2-volt AA rechargeable
batteries can also be used. A charge jack located
below the on/off switch is provided for convenient
recharging.

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

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.

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 8 cells to power the transmitter, the DX3R
uses 4 cells. This is due to the electronics being
more efficient. When charging, be sure to use a
charger designed for 4 cells (4.8-volt battery pack)
when charging the transmitter. 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.

sTeerIng TensIon adjusTMenT

Steering tension is adjusted via the recessed
screw located below the steering wheel (see
Steering Tension Adjustment on the previous page).
Using a small Phillips screwdriver, turning the
screw clockwise increases steering tension while
turning the screw counterclockwise reduces
steering tension.

ModelMaTCh

The DX3R features patented 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

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).

bIndIng

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).

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 SR3100 features DSM2 second­generation technology and is only compatible
with transmitters that utilize DSM2 protocol (Like
the DX3R) DSM1 transmitters will not operate the
SR3100 receiver.

1. With the receiver off, insert the bind plug into the Batt/
Bind port in the receiver.

2. Power the receiver. The amber LED will flash
continuously, indicating that the receiver is in bind
mode.

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.

5. Rotate the roller to highlight the Bind screen and press
the roller to access this screen.

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: Some Spektrum receivers like the
AR3000 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.

6. Rotate the roller to highlight BIND.

The DX3R features DSM2 technology but is also
compatible with most DSM1 Spektrum surface
receivers. When the fastest response rate is desired,
using the system with a DSM2 receiver like the
AR3100 is recommended as this combination gives
the lowest possible latency/ quickest response rate.
During the binding process the transmitter actually
“learns” the receiver type (DSM1 or DSM2) and
configures itself to transmit that protocol.

ChangIng To
lefT-handed ConfIguraTIon

The DX3R is shipped set up for right-handed use but
can easily be switched to left-handed configuration.
All the parts necessary to convert to left-handed,
including the grip plates, the back cover and the
front shell are included. A 3/32-inch hex wrench and
a small Phillips screwdriver will be needed.

3. Use a 3/32inch hex wrench remove the three
screws on the front of the steering housing
as shown.

1. Remove the batteries from the transmitter. This
prevents the possibility of accidentally causing a
short during the conversion.

2. Carefully remove the grip cover by prying
with your fingers at the forward edge of the
rubber grip.

4. Carefully remove the steering mechanism
and unplug the steering connector. Also
remove the backplate.

5. Using a small Phillips screwdriver, remove the
four Phillips screws (two per side) that fasten the
grip plates in place and remove the grip plate that
doesn’t have the buttons attached.

10 SPEKTRUM DX3R PROGRAMMING GUIDE

6. Carefully pull out the grip plate that contains
buttons D, E and F. Use a Phillips screwdriver
remove the PC board and backplate from the grip
plate. Note the positions of the three buttons.

7. Transfer the three buttons (D,E and F) to the other
“handed” grip plate noting that the buttons fit in
a specific direction such that they fit the external
contour of the grip plate.

9. Place both grip plates in place and fasten them
using four Phillips screws (two per side).

10. Push the steering wheel connector through the

transmitter case to the opposite side.

8. Carefully screw the PC board and backplate
in place and test that all buttons are
depressing properly.

11. Select the opposite “handed” steering shell and
pass the steering wheel mechanism connector
through the hole in the shell.
