SPEKTRUM DX18 • TRANSMITTER INSTRUCTION MANUAL

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 fl ight, ALWAYS confi rm the failsafe functions as you would expect. 

SmartSafe is a failsafe acting only on the throttle channel that 
offers the following benefi ts:

• 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.

1. Power the transmitter and receiver on.
2. Power off the transmitter. The throttle should immediately 
move to the failsafe position.

 Make sure the aircraft is restrained on the 

ground. If failsafe is not set, your aircraft might advance to mid 
or full throttle.

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. 

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.

 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.

The Preset failsafe moves all channels to their programmed 
failsafe positions. 
We recommend using Preset failsafe to deploy spoilers on 
sailplanes to prevent a fl yaway if radio signal is lost.

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 fl ash rapidly. The 
orange receiver LEDs continue fl ashing.

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.

 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.
