SPEKTRUM DX18 • TRANSMITTER INSTRUCTION MANUAL
EN
You establish failsafe positions when you bind your transmitter
and receiver. If the radio signal connection is lost between the
transmitter and receiver, the receiver immediately moves the
aircraft control surfaces to the failsafe positions. 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.

Failsafe
SmartSafe failsafe is a technology that only acts on the throttle
channel and 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 position
before putting the transmitter into bind mode.
To Test the SmartSafe failsafe
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 fully restrained on
the ground. If the failsafe is not set correctly, 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 the 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 to the desired Hold Last
Command position 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 fully restrained on
the ground. If the failsafe is not set correctly, 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 sail-
planes to prevent a fl yaway if the 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 fl ash rapidly. The
orange receiver LEDs will 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 turn solid.
CAUTION: Make sure the aircraft is fully restrained on
the ground. If the failsafe is not set correctly, the aircraft
throttle might advance to mid or full throttle.
