Setting the Failsafe Positions
The Receiver features two types of failsafe: SmartSafe and Preset Failsafe.
SmartSafe
SmartSafe failsafe is recommended for most aircraft.
™
When the transmitter and receiver are turned on, the receiver connects to the
transmitter and normal control of all channels occurs. If loss of signal occurs,
SmartSafe moves the throttle channel to its preset failsafe position (low throttle)
that was set during binding. All other channels hold their last position. When the
receiver detects signal from the transmitter, normal aircraft operation resumes.
Programming SmartSafe
SmartSafe failsafe is on by default, no programming is necessary.
Preset Failsafe (Spektrum AS3X Application required)
Preset failsafe is ideal for sailplanes and is preferred by some modelers for
their glow- and gas-powered aircraft.
The Spektrum application enables you to program preset failsafe positions on
individual receiver channels. If loss of signal occurs, Preset failsafe drives the
selected servo channels to their preset failsafe positions.
You must use the Spektrum AS3X application to program Preset Failsafe.
Receiver Power Only
• With SmartSafe or Preset Failsafe, when the receiver only is turned on (no
transmitter signal is present), the throttle channel has no output, to avoid
operating or arming the electronic speed control.
• All other channels have no output until the receiver has linked to the transmitter.
Range Testing
Before each flying session and especially with a new model, it is important to
perform a range check. All Spektrum aircraft transmitters incorporate a range
testing system which, when activated, reduces the output power, allowing
a range check.
1. With the model restrained on the ground, stand 30 paces (approx. 90
feet/28 meters) away from the model.
2. Face the model with the transmitter in your normal flying position and place
your transmitter into range check mode.
3. You should have total control of the model with the button depressed at 30
paces (90 feet/28 meters).
4. If control issues exist, contact the appropriate product support department.
