How To Program
1. Insert the bind plug and power on the receiver.
2. When the receiver LEDs blink indicating bind mode, remove bind plug before
binding the transmitter to the receiver.
3. LED lights will continue to blink.
4. Move transmitter’s control sticks and switches to the desired Preset Failsafe
positions then turn it on in bind mode.
5. The system should connect in less than 15 seconds.
NOTICE: Failsafe features vary according to receiver, so if using a receiver other
than the AR12020, consult your receiver’s instructions for the failsafes that apply.
Before flight, ALWAYS confirm your binding is good and failsafe is set. To do
this, make sure the system is connected, turn your transmitter off. Confirm that
low-throttle is active.
CAUTION: Make sure the aircraft is restrained on the ground. If failsafe is
not set, your aircraft might advance to mid or full throttle.
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.
Press and hold the bind button
30 paces (90 feet/28 meters)
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. This causes reduced power output from the
transmitter.
3. You should have total control of the model in range test mode at 30 paces
(90 feet/28 meters).
4. If control issues exist, call the Horizon Product Support office.
Receiver Power System Requirements
Inadequate power systems that do not provide the necessary minimum voltage to
the receiver during flight are the number one cause of in-flight failures. Some of
the power system components that affect the ability to properly deliver adequate
power include:
• Receiver battery pack (number of cells, capacity, cell type, state of charge)
• The ESC’s capability to deliver current to the receiver in electric aircraft
• The switch harness, battery leads, servo leads, regulators etc.
