SmartSafe ™ Failsafe
SmartSafe technology is a safety feature on the throttle channel only that offers
the following benefits:
• Prevents electric motors from operating when the receiver only is turned on
(no transmitter signal present)
• Prevents the speed controller from arming until the throttle is moved to low
throttle position after connection is made
• Powers off electric motors and reduces gas/glow engines to idle if signal is
lost (must bind the receiver at throttle off or idle position).
• If throttle is at any position other than low, the ESC won’t arm
• If connection is lost in flight, SmartSafe technology sets the throttle to the
position it was in during the binding process (normally low throttle or idle).
How to Program SmartSafe Falilsafe
SmartSafe is automatically set when the system is bound. It’s important to have
the throttle stick in the low position to store low throttle settings during binding.
CAUTION: For electric aircraft, always remove the propeller from the
motor before testing the failsafe.
Range Testing
Before each flying session, and especially with a new model, 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 on the ground and the motor off, 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. This causes reduced
power output from the transmitter.
3. You should have total control of the model in range test mode at 30 paces
(approx. 90 feet/28 meters)
4. If control issues exist, call the Horizon Product Support office.
