BINDING
Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifier) code of a single specific trans-
mitter. The DX18 and AR9020 are pre-bound at the factory. You will need to rebind after the model programming is initially set up to
fully program the model’s failsafe positions.

PROGRAMMING FAILSAFE POSITIONS
You establish failsafe positions when you bind your transmitter and receiver. If radio signal connection is lost between the transmitter
and receiver, the receiver immediately moves the aircraft control surfaces to the failsafe positions. The Spektrum AR9020 receiver
has three failsafes programming options: SmartSafe, Hold Last Command, and Preset.
If you assign the receiver THRO channel to a transmitter channel other than throttle , we recommend using Preset failsafe with the
throttle in the low position.
NOTICE: Failsafe features vary according to receiver. Always consult the receiver instruction manual for failsafe features.
Before flight, ALWAYS confirm the failsafe functions as you would expect.
SmartSafe Failsafe
SmartSafe is a failsafe acting only on the throttle channel that
offers the following benefits:
• Prevents electric motors from operating when the receiver
power is on and the transmitter power is off.
• Prevents the speed controller from arming until the throttle is
moved to the low throttle position.
• Powers off an electric motor and reduces gas/glow engines
to idle if signal is lost.
To Program SmartSafe, move the throttle to the low or off posi-
tion before putting the transmitter in bind mode.
To Test the SmartSafe
1. Power the transmitter and receiver on.
2. Power off the transmitter. The throttle should immediately
move to the failsafe position.
CAUTION: Make sure the aircraft is restrained on the
ground. If failsafe is not set, your aircraft might advance to mid
or full throttle.
Hold Last Command
The Hold Last Command failsafe maintains the last command
on all channels except throttle; if radio signal is lost, the aircraft
maintains the commanded heading until the receiver regains
signal.
To program Hold Last Command, follow the provided binding
instructions in this instruction manual.
To Test Hold Last Command
1. Power on the transmitter and receiver.
2. Move one of the control sticks and hold the input.
3. While holding the control input, for example, a small amount
of rudder, power off the transmitter. The rudder should
maintain the input command.
CAUTION: Make sure the aircraft is restrained on the
ground. If the failsafe does not function as you would expect, the
aircraft throttle might advance to mid or full throttle.
Preset Failsafe
The Preset failsafe moves all channels to their programmed
failsafe positions.
We recommend using Preset failsafe to deploy spoilers on
sailplanes to prevent a flyaway if radio signal is lost.
To program Preset failsafe:
1. Insert the bind plug in the bind port on the receiver and
power on the receiver.
2. Remove the bind plug when the orange LED on the main
receiver and all attached remote receivers flash rapidly. The
orange receiver LEDs continue flashing.
3. Move the transmitter control sticks and switches to the
desired Preset failsafe position. Power the transmitter on.
4. Failsafe programming is complete when the orange LEDs on
the transmitter and all receivers are on solid.
CAUTION: Make sure the aircraft is restrained on the
ground. If the failsafe does not function as you would
expect, the aircraft throttle might advance to mid or full throttle.

X-Plus Channels and Failsafe
Failsafe is not supported for servos connected to the X-Plus
Module. We recommend that no failsafe should be expected or
attempted for a servo connected through the X-Plus Module.
However, servos connected to the X-Plus Module will hold last
command in the event of a failsafe condition.

1. Open the Frame Rate Menu in System Setup.
2. Scrolll to X-Plus and press the scroll wheel to activate. The
X-Plus Inputs screen is now active in the Channel Assign
menu.
AUX6 and AUX7 channels are available on 12-channel receivers
when X-Plus is active. AUX6 and AUX7 are 2048 resolution and
22ms frame rate (12-channel receivers only).
Channels X+1 and X+2 are duplicate channels of channels 11
and 12 on a 12 channel receiver with X-Plus active. If chan-
nels 11 and 12 require any adjustment for travel adjust, servo
reversing, sub trim or any other function, adjust channels X+1
and X+2. Note that channels 11 and 12 will also show on the
X-Plus monitor as channels X+1 and X+2.
If you select 11ms frame rate before you activate X-Plus, the
transmitter reverts to 22ms frame rate when X-Plus is active.
CAUTION: Do NOT connect throttle or any primary
control surface to the X-Plus Module. The X-Plus chan-
nels are intended to be used for auxiliary functions only. X-Plus
channels have a resolution of 512 and variable latency from
22ms to about 88ms. When X-Plus is active, the first 10 chan-
nels default to 22ms.
Refer to community.spektrumrc.com for more information about
X-Plus options.

Frame Rate
The Frame Rate menu enables you to change the frame rate,
modulation mode and activate XPLUS.
Select the option you wish to change and press the scroll wheel.
Frame Rate
You must use digital servos if you select 11ms frame rate.
Analog or digital servos can be used with 22ms frame rate.
Modulation Mode
We recommend using DSMX (default) modulation mode. When
DSMX is active, the transmitter operates in DSMX with DSMX
receivers and DSM2 with DSM2 receivers. The transmitter au-
tomatically detects DSM2 or DSMX during binding and changes
the mode accordingly to match the receiver type you are using.
If you select DSM2, the transmitter operates in DSM2 regardless
of whether it is bound to a DSM2 or DSMX receiver.
X-Plus Activation
Activate X-Plus channels in the Frame Rate Screen. You can set
X-Plus to INH (inhibit) or Act (activate).
NOTICE: While DSMX allows you to use more than 40 trans-
mitters simultaneously, do not use more than 40 transmitters
simultaneously when using a DSM2 receiver or a transmitter in
DSM2 mode.
CAUTION: Do NOT connect throttle or any primary
control surface to the X-Plus Module. The X-Plus
channels are intended to be used for auxiliary functions only.
X-Plus channels have a resolution of 512 and variable latency
from 22ms to about 88ms. When X-Plus is active, the first 10
channels default to 22ms.
Preflight Setup
The Preflight Setup menu option enables you to program a
pre-flight checklist that appears each time you power on the
transmitter or when you select a new model memory. Each item
on the list must be confirmed before you can access the Main

Enabled
When Enabled is set to NO, Data Logging is turned off.
Select YES to save Telemetry data to the SD Card. The SD Card
must be installed in the transmitter to select YES.
CAUTION: If you access the Telemetry menu from the
Function List, you may see a Frame Loss appear when
you exit the menu. The Frame Loss is not an error, however there
is a momentary loss of radio signal when exiting the Telemetry
screen. Do NOT access the Telemetry menu during flight.
Bind
The Bind menu enables you to bind a transmitter and receiver
without powering off the transmitter. This menu is helpful if you
are programming a model and need to bind the receiver for
failsafe positions.
See “Programming Failsafe Positions” for more information.

Trainer
The DX18 features a programmable trainer function with 4
trainer modes. The transmitter assigns the trainer function to
Switch I. The 4 trainer modes include:
Inhibit
In Inhibit, the slave transmitter must have the same program-
ming as the master transmitter (e.g., servo reversing, travel
adjust, sub-trim, trims).
Programmable
Programmable mode enables you to program the master trans-
mitter to transfer any or all individual channels when you activate
the trainer switch. This mode is ideal for beginners learning to
control individual channels while the master transmitter
maintains control of all other channels.
The slave transmitter should be in PilotLink Slave mode, if
available. It is not necessary to have model programming in the
slave transmitter.
Pilot Link Master
When Pilot Link Master is active, the slave transmitter controls
the primary stick functions (Throttle, aileron, elevator and rudder)
while the master maintains control of all other channels and
functions (including dual rates and auxillary switch positions).
PilotLink Master is ideal for complex models as the master
transmitter maintains control of all secondary functions, for
example filght modes, retracts, flaps and brakes.
Slave
Use Slave mode when using the DX18 as a slave transmitter and
PilotLink is active in the master transmitter.
DX18 Trainer Operation
1. Bind the master transmitter to the model.
2. Connect the trainer cord (SPM6805) to the back of the
master transmitter.
3. Make sure the master and slave transmitter battery packs
are fully charged.

transmitter receives power when you connect the trainer
cord.
5. Connect the trainer cord to the slave transmitter.
6. The slave transmitter screen displays information but does
not send a signal to the model.
7. Press the trainer button on the master transmitter to transfer
model control from the master to the slave.
8. Release the trainer button and the master transmitter
regains control of the model..
