SAFETY PRECAUTIONS

• Always ensure all batteries have been properly charged
prior to using the model.

• Always check all servos and their connections prior to each run.

• Never operate your model near spectators, parking areas
or any other area that could result in injury to people or
damage of property.

• Never operate your model during adverse weather
conditions. Poor visibility can cause disorientation and loss
of control of your model.

• Never point the transmitter antenna directly toward the
model. The radiation pattern from the tip of the antenna is
inherently low.

• 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.

INSTALLING THE BATTERIES

CAUTION: Risk of explosion if battery is replaced

by an incorrect type. Dispose of used batteries

according to national regulations.

CAUTION: If using rechargeable batteries, charge

only rechargeable batteries. Charging non­rechargeable batteries may cause the batteries to burst,
resulting in injury to persons and/or damage to property.

RECEIVER COMPATIBILITY

The DX2E is compatible with all Spektrum

™

DSMR® and

DSM2® receivers.

RECEIVER CONNECTION AND IN­STALLATION

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 failsafe mode. When the transmitter is turned on,
normal control is resumed. For more information on setting
the failsafe, refer to the Binding a Receiver section above.

TYPICAL ELECTRIC INSTALLATION

Install the Receiver in your vehicle using double-sided foam
servo tape. Foam servo tape will hold the receiver in place
and help isolate it from vibrations. Mount the antenna up
and away from the vehicle in an antenna tube. The higher up
the antenna is, the better signal it will receive.

CAUTION: Do not cut the antenna.

TYPICAL GAS INSTALLATION

BINDING A RECEIVER

Binding is the process of programming the receiver to
recognize the GUID (Globally Unique Identifier) code of a
single specific transmitter. When a receiver is bound to a
transmitter, the receiver will only respond to that specific
transmitter. The DX2E and SR310 are bound at the factory,
but if you need to rebind for any reason, please follow these
steps:

1. With the receiver off, insert the bind plug into the BIND
port on the receiver.

2. Power the receiver through any other port. The green
LED will flash continuously, indicating the receiver is in
bind mode.

3. With the steering wheel and throttle trigger in the desired
preset failsafe positions (see the Failsafe section on this
page for more information), press and hold the bind
button and turn on the transmitter. The green LED on the
front of the transmitter will flash within three seconds,
indicating the transmitter is in bind mode. Release the
bind button when the green LED flashes. Continue to
hold the failsafe positions until the binding process is
complete.

4. The LED on the receiver will glow solid when the
transmitter and receiver are bound.

5. Remove the bind plug and store it in a convenient place.

You must rebind when:

• Different failsafe positions are desired e.g., when throttle
or steering reversing has been changed.

• Changing receiver types e.g., changing from a DSM2
receiver to DSMR receiver.

• Binding the receiver to a different transmitter.

Solid Green Battery is good (Above 4V)
Flashing Green Battery voltage is critically low.

Replace batteries (below 4V)

SERVO REVERSING

If a right steering command does not result in the wheels
turning right (and vice versa), the channel may need to be
reversed. To reverse a channel, switch the position of the
correlating switch—“N” is for normal, “R” is for reverse.

THROTTLE LIMITER

The Throttle Limiter switch limits the throttle ouput from
50/70/100%.This is useful for limiting motor ouput on slick or
loose traction tracks or to limit vehicle speeds for new drivers.

3-POSITION SWITCH

The 3-Position Switch is used to control a third channel and
is factory preset at -100%/Neutral/100%.

STEERING TRIM

The steering trim dial is used to adjust the steering trim
when the wheel is centered. Rotating the dial changes the
steering trim (the steering at rest position). Normally, the
steering trim is adjusted until the vehicle tracks straight.

THROTTLE TRIM

The throttle trim dial is used to adjust the throttle trim
when the throttle stick is released (neutral position). This is
typically used to adjust the brakes. Rotating the dial causes
the throttle trim (the throttle position at rest) to be changed.

CHANGING THE TRAVEL ADJUST
SETTINGS

The travel function supports precise endpoint adjustments in
each direction for the steering and throttle channels.

1. Hold the trigger in the full brake position and the steering wheel
in full right position while powering on the transmitter. The LED
flashes rapidly, indicating the programming mode is active.

2. Throttle End Point: Hold the trigger in the full throttle position.
Turn the TH TRIM knob to adjust the full throttle end point.

3. Brake End Point: Hold the trigger in the full brake position.
Turn the TH TRIM knob to adjust the full brake end point.
Return the trigger to the center position.

4. Left Steering End Point: Hold the steering wheel in the full left
position. Turn the ST TRIM knob to adjust the left end point.

5. Right Steering End Point: Hold the steering wheel in the full
right position. Turn the ST TRIM knob to adjust the right end
point. Return the steering wheel to the center position.

6. Power off the transmitter to save the travel adjust settings.
The minimum Travel is 75%, and the Maximum travel is
150%. The default travel settings are 125% steering and
100% throttle.

IMPORTANT: If the travel is changed on the DX2E, you must
rebind and calibrate AVC® Receivers.

STEERING RATE AND GAIN CONTROL

Steering rate (also known as dual rate) allows on-the-fly
steering travel adjustments to be made using the ST Rate
dial. Steering rate limits the amount of travel of the steering
servo. The steering rate cannot be greater than 100%.
When the DX2E is bound to a DSMR® AVC® receiver, the
ST RATE knob controls the sensor gain value. Turn the knob
counterclockwise to reduce the gain or clockwise to increase
the gain.
