PROGRAMMING FAIlSAFE POSITIONS

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.
SmartSafe™ Failsafe
SmartSafe failsafe is a technology that only acts on the
throttle channel and 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.

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.

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 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 rapidly flash.
The orange receiver LEDs will continue flashing.

NOTICE: Failsafe features vary according to receiver. Always
read the receiver instruction manual for failsafe features.
Before flight, ALWAYS confirm the failsafe functions as you
would expect.
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.
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.
3. Move the transmitter control sticks and switches to the
desired Preset failsafe position. Power the transmitter
on and place the transmitter in Bind mode.
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.
