Installing the Transmitter Batteries
Remove the battery cover, install the four included batteries
(noting proper polarity) and reinstall the battery cover.
Low Battery Alarm
The LED indicator ashes and the transmitter beeps progressively faster as the battery voltage drops.Replace the
transmitter batteries when the transmitter begins to beep.
CAUTION: If using rechargeable batteries, charge
only rechargeable batteries. Charging nonrechargeable batteries may cause the batteries to burst,
resulting in injury to persons and/or damage to property.
WARNING: Do not pick up the transmitter by
the antenna. Do not alter or put weight on the
antenna. Damage to antenna parts can decrease transmitter signal strength, which can result in loss of model
control, injury or property damage.
For complete transmitter instructions and features, visit
horizonhobby.com.
Battery Voltage Level
The included DXS transmitter includes a new ight battery
voltage level indicator feature.
LED SMART Battery voltage indication is based on current
voltage and will change with throttle/power usage. When
throttle is increased, voltage drops, causing the bars to
indicate lower power (e.g., fewer LEDs solid or ashing.)
When the throttle is lowered to idle/off, the bars recover
(e.g., more LEDs solid or ashing). LED bars will rise and
lower depending on throttle/power usage.
The SMART Battery low voltage alarm sounds when the
ESCs are close to reaching low voltage cutoff. The alarm
will sound for 25 seconds. If the throttle is lowered to allow
voltage recovery, the alarm will stop early.
Land the aircraft when the alarm sounds.
After landing, reset the SMART Battery low voltage warning
by either (1) powering cycling the DXS transmitter, or (2)
disconnecting the battery from the aircraft for more than
15 seconds or until the LED voltage indication bars go out.
Connect a fully charged battery to the aircraft, which will
ensure the SMART Battery low voltage warning resets prior
to the next ight.

Transmitter and Receiver Binding
CAUTION: Connecting the battery to the ESC with
reversed polarity will cause damage to the ESC,
the battery or both. Damage caused by incorrectly connecting the battery is not covered under warranty.
IMPORTANT: The included ight controller has been
programmed for operation specically in this aircraft. The
programming in this ight controller cannot be changed by
the user.
An extension is installed in the ight controller bind port
so binding may be done through the battery door in the
bottom of the aircraft without having to remove the wing
assembly. Simply insert the bind plug in the open end of
the extension marked “bind” to enter bind mode.
The included RTF transmitter is bound to the aircraft at the
factory. If you need to re-bind for any reason, follow the
binding procedure as shown.
You need to ‘bind’ your chosen Spektrum™ DSM2®/DSMX®
technology equipped aircraft transmitter to the receiver for
proper operation. Please refer to the optional parts list in this
manual or visit www.bindny.com for a list of compatible
transmitters.
Refer to your transmitter instructions for binding to a receiver.
The throttle will not arm if the transmitter’s throttle stick is not
put at the lowest position and the throttle trim centered or lower.
If you encounter problems, follow the binding instructions
and refer to the transmitter troubleshooting guide for other
instructions. If needed, contact the appropriate Horizon
Product Support ofce.
Binding Procedure Reference Table
1. Make sure the transmitter is powered off.
2. Make sure the transmitter controls are neutral, the
throttle is at the lowest position*, the throttle trim is
centered and the aircraft is immobile.
3. Install a bind plug in the bind port extension.
4. Connect the ight battery to the ESC. The ESC will
produce a long tone followed by a series of additional
short tones.
5. The status LED will begin to ash rapidly.
6. Power on the transmitter while holding the transmitter bind button or switch. Refer to your transmitter’s
manual for specic binding instructions.
7. When the receiver binds to the transmitter, the orange
bind light on the receiver will turn solid and the ESC will
produce ascending tones. The tones indicate the ESC is
armed, provided the throttle stick and throttle trim are
low enough to trigger arming.
8. Remove the bind plug from the bind port. The receiver
should retain the binding instructions received from the
transmitter until another binding is done.
9. Safely store the bind plug (some owners attach the
bind plug to their transmitter using two-part loops and
clips).
* The throttle will not arm if the transmitter’s throttle stick is not put at the lowest position. The
aircraft will not arm when it is upside down.

Applies only when the optional GPS module is installed
IMPORTANT: IF THE OPTIONAL GPS MODULE IS INSTALLED the aircraft will not respond to transmitter commands after binding if it cannot acquire a
GPS signal.
Binding: After binding with the GPS module installed, the aircraft will search for a GPS lock, indicated by the elevator slowly cycling up and down. After
acquiring a GPS lock, all ight controls will respond normally except throttle. The throttle will be limited, allowing the aircraft to be taxied out to takeoff
position on the runway. Set the home position to regain full functioning throttle. See the Powering On With GPS section of this manual for further details.
Compass calibration: After binding the rst time with the GPS module installed in the aircraft, compass calibration is required. The aircraft will automatically
enter the compass calibration sequence after installing the GPS for the rst time. This is indicated by the ailerons slowly cycling up and down. The aircraft will
not respond to transmitter commands with the GPS module installed until calibration has been completed. See the Compass Calibration section of this manual
for further details.
Subsequent binding with the GPS module will not require compass calibration.

Flight Control
EN
For smooth control of your aircraft, always make small
corrections. All directions are described as if you were
sitting in the aircraft.
• Flying faster or slower: When your aircraft is stable in
the air, push the throttle stick up to make the aircraft
go faster. Pull the throttle stick back to slow down. The
aircraft will climb when the throttle is increased.
• Elevator up and down: Push the elevator stick forward
to make the aircraft go down. Pull the elevator stick
back to go up.
• Aileron right and left: Move the aileron stick right to
make the aircraft roll or “bank” right. Move the aileron
stick left to bank left.
TIP: Always picture yourself in the aircraft when
determining which way to bank the aircraft wings.
When the aircraft is ying away from you, banking
the aircraft right or left appears normal. When ying
toward you, the aircraft will appear to bank the opposite
direction to the control input given. This will become
more instinctual with experience.
• Rudder left and right: Push the rudder stick left or right
to yaw or point the nose of the aircraft left or right. The
rudder stick is also used to steer the aircraft left and
right while taxiing on the ground.
TIP: Similar to the tip given for the aileron control, picture yourself in the aircraft to determine which direction
to point the nose depending on whether you are ying
away from yourself or toward yourself.
For rst ights, set the SAFE® ight mode switch to Begin-
ner Mode (position 0).
IMPORTANT: Even though SAFE technology is a very
helpful tool, the aircraft still needs to be own manually.
If incorrect input is given at lower altitudes or at slower
speeds, the aircraft can crash. Study these control inputs
and the aircraft response to each carefully before attempting your rst ight.

Install the Flight Battery
Battery Selection
• We recommend the E-ite® 2200mAh 11.1V 3S 30C
Li-Po (SPMX22003S30).
• If using another battery, the battery must be at least a
2200mAh battery.
• The battery should be approximately the same capacity,
dimensions and weight as the E-ite Li-Po battery to t
in the fuselage without changing the center of gravity a
large amount.
1. Lower the throttle stick to the lowest setting and center
the throttle trim. Power on the transmitter, then wait 5
seconds.
2. Apply a strip of hook tape (A) to the bottom the battery
near the end opposite the battery wires.
3. Turn the latch (B) and open the battery hatch.
4. Install the ight battery as shown. See the Adjusting the
Center of Gravity instructions for more information.
5. Make sure the ight battery is secured using the hook
and loop strap (D).
6. Connect the battery to the ESC. Close the hatch and turn
the aircraft over and place it on its wheels. Keep the
aircraft immobile and away from wind for 5 seconds.
7. Keep the aircraft immobile for 30+ seconds until GPS
lock is established as described in the Flying section.
CAUTION: Always disconnect the Li-Po ight
battery from the aircraft when not ying to avoid
over-discharging the battery. Batteries discharged to
a voltage lower than the lowest approved voltage may
become damaged, resulting in loss of performance and
potential re when batteries are charged.
CAUTION: Always keep hands away from the
propeller. When armed, the motor will turn the
propeller in response to any throttle movement.

Center of Gravity (CG)
An aircraft with the correct CG has its weight balanced on
the center of the aircraft for safe, stable ight.The aircraft
CG and weight are based on an E-ite 11.1V 2200mAh
30C battery (SPMX22003S30) installed. Make sure the
ight battery is secured using the hook and loop strap.
The CG location is 62-68mm back from the leading edge
of the wing at the root. Balance the aircraft on your ngertips near the fuselage under the wings.
• If the nose goes down, move the ight battery back
until the aircraft balances.
• If the nose goes up, move the ight battery forward
until the aircraft balances.
When in intermediate and experienced modes, if the
aircraft CG is too far forward (nose heavy), up elevator is
required to y level at 50%– 60% power. If the aircraft CG
is too far aft (tail heavy), down elevator is required to y
level. In Beginner mode the aircraft is not affected. The
SAFE system controls the aircrafts attitude.
Adjust the battery position as needed.
