6. After setting up your model, rebind the system so the true low throttle and
neutral control surface positions are set.
NOTICE: Remove the bind plug to prevent the system from entering bind mode the
next time the power is turned on.
SmartSafe™ Failsafe
SmartSafe Failsafe is always active in both the hold last command failsafe and in
the preset failsafe. SmartSafe technology is a safety feature on the throttle channel
that offers the following benefits:
(no signal present)
throttle position after connection is made
is lost
position it was in during the binding process.
How To Program
The SmartSafe program is automatically set when the hold last command failsafe or
Preset failsafe is programmed or the system is bound. Always to have the throttle
stick in the low position to store low throttle during binding.
To Test
Confirm the failsafe setting is correct by turning off the transmitter. The throttle
should go to the preset low throttle 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
If you lose connection, all channels except for throttle channel hold last given
command and the aircraft continues on its path. So, if you were turning when
connection was lost, your aircraft would continue turning.
How to Program
1. Leave the bind plug in the bind port through the entire binding process.
2. Remove bind plug only after receiver connects to transmitter
To Test
Confirm the failsafe settings are correct by turning off the transmitter. All channels
except for the throttle should hold the last command.
CAUTION: Make sure the aircraft is restrained on the ground. If failsafe is
not set, your aircraft might advance to mid or full throttle.
Preset Failsafe
If the signal is lost, all channels are driven to their failsafe position set during
binding. Preset Failsafe is ideal for sailplanes, as spoliers can be deployed during
loss of signal, preventing a flyaway.
