General Binding Tips and Failsafe
• The included receiver has been specically programmed
for operation of this aircraft. Refer to the receiver manual
for correct setup if the receiver is replaced.
• Keep away from large metal objects while binding.
• Do not point the transmitter’s antenna directly at the receiver while binding.
• The orange LED on the receiver will ash rapidly
when the receiver enters bind mode.
• Once bound, the receiver will retain its bind settings
for that transmitter until you re-bind.
• If the receiver loses transmitter communication, the failsafe will activate.
Failsafe moves the throttle channel to low throttle. Pitch and roll
channels move to actively stabilize the aircraft in a descending turn.
• If problems occur, refer to the troubleshooting guide or if needed,
contact the appropriate Horizon Product Support ofce.
Transmitter and Receiver Binding / Enabling SAFE Select
The BNF Basic version of this airplane includes SAFE Select technology, enabling you to choose the level of ight protection. SAFE mode includes angle limits and
automatic self leveling. AS3X mode provides the pilot with a direct response to the control sticks. SAFE Select is enabled or disabled during the bind process.
With SAFE Select disabled the aircraft is always in AS3X mode. With SAFE Select enabled the aircraft will be in SAFE Select mode all the time, or you can assign a switch
to toggle between SAFE Select and AS3X modes.
IMPORTANT: Before binding, read the transmitter setup section in this manual and complete the transmitter setup table to ensure your transmitter is properly
programmed for this aircraft.
IMPORTANT: Move the transmitter ight controls (rudder, elevators, and ailerons) and the throttle trims to neutral. Move the throttle to low before and
during binding.
You can use either the bind button on the receiver or the conventional bind plug to complete the binding process.
A bind plug extension has been provided in BNF Basic version models. It will be labeled and located in the battery or radio compartment for easy access.

AS3X Response Test
Aircraft movement AS3X Reaction
ElevatorAileronRudder
This test ensures that the AS3X®control system is functioning properly. Assemble
the aircraft and bind your transmitter to the receiver before performing this test.
1. Raise the throttle just above 25%, then lower the throttle to activate AS3X.
CAUTION: Keep all body parts, hair and loose clothing away from a
moving propeller, as these items could become entangled.
2. Move the entire aircraft as shown and ensure the control surfaces move in
the direction indicated in the graphic. If the control surfaces do not respond
as shown, do not y the aircraft. Refer to the receiver manual for more
information.
Once the AS3X system is active, control surfaces may move rapidly. This is normal.
AS3X remains active until the battery is disconnected.
Due to different effects of torque, lift, and drag some aircraft require trim changes
with different speeds and throttle settings. Mixes are preloaded into the receiver to
compensate for these changes. The mixes become active the rst time the throttle
is raised above 25%. The control surfaces may be offset slightly at different throttle
settings after the rst time throttle is raised. Trimming the plane in ight should be
done at 80-100% throttle for best results.

SAFE Select Flying Tips
When flying in SAFE Select mode the aircraft will return to level flight any time the
aileron and elevator controls are at neutral. Applying aileron or elevator control
will cause the airplane to bank, climb or dive. The amount the stick is moved will
determine the attitude the airplane flies. Holding full control will push the aircraft
to the pre-determined bank and roll limits, but it will not go past those angles.
When flying with SAFE Select, it is normal to hold the control stick deflected with
moderate aileron input when flying through a turn. To fly smoothly with SAFE Select,
avoid making frequent control changes and don’t attempt to correct for minor devia-
tions. Holding deliberate control inputs will command the aircraft to fly at a specific
angle, and the model will make all corrections to maintain that flight attitude.
When flying with SAFE Select, throttle will make the aircraft climb or descend. Full
throttle will cause the aircraft to pitch up and climb slightly. Mid throttle will keep the
airplane flying level. Low throttle will cause the airplane to descend slightly nose-down.
Return the elevator and aileron controls to neutral before switching from SAFE
Select mode to AS3X mode. If you do not neutralize controls when switching into
AS3X mode, the control inputs used for SAFE Select mode will be excessive for
AS3X mode and the aircraft will react immediately.
Differences between SAFE Select and AS3X modes
This section is generally accurate but does not take into account flight speed,
battery charge status, and other limiting factors.

Center of Gravity (CG)
The CG location is measured from the leading edge of the wing. This CG location
has been determined with the recommended 3S 1300mAh Li-Po battery
(SPMX133S30) installed to the front edge of the battery tray. Adjust the battery
forward or aft as needed to achieve the proper CG location.
CAUTION: Install the battery but do not arm the ESC while checking the CG.
Personal injury may result.

edge.
In-Flight Trimming
During your rst ight, trim the aircraft for level ight at 80-100% throttle. Make
small trim adjustments with your transmitter’s trim switches to achieve straight
and level ight.
After adjusting trim do not touch the control sticks for 3 seconds. This allows the
receiver to learn the correct settings to optimize AS3X performance.
Failure to do so could affect ight performance.
