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 fl ight, ALWAYS confi rm the failsafe functions as you would expect.
SmartSafe Failsafe
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.
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.
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 fl yaway 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 fl ash rapidly. The
orange receiver LEDs continue fl ashing.

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.
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.
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.
