Y-Harnesses and Servo Extensions
Do not use amplified Y-harnesses or amplified servo extensions with Spektrum equipment.
Use only standard non-amplified Y-harnesses and servo extensions. When converting existing
models to Spektrum devices, replace all amplified Y-harnesses and servo extensions.
SmartSafe
SmartSafe 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
SmartSafe sets the throttle to the position it was in during the binding process (normally low
throttle or idle).
How To Program
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 during binding.
To Test
Electric helicopters: Remove the pinion gear from the motor before testing.
Gas or glow helicopters: Test the servo positions with the engine off.
Confirm the failsafe setting is correct by turning off the transmitter. The throttle should go to
the preset low throttle position. All other channels should hold the last commanded position.

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/engine 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.
4. If control issues exist, call the Horizon Product Support office.
