Transmitter and Receiver Binding
Bind Plug Installation
BIND PLUG
Binding is the process of programming the receiver to recognize the GUID
(Globally Unique Identifier) code of a single specific transmitter. You need to
‘bind’ your chosen Spektrum™DSM2®/DSMX®technology equipped aircraft
transmitter to the receiver for proper operation.
IMPORTANT: Before binding a transmitter, read the Transmitter Setup section
of this manual to ensure that your transmitter is properly programmed for this
aircraft.
Binding Procedure
IMPORTANT: The included AR400 receiver has been programmed for
operation specifically for this aircraft. Refer to the receiver manual for cor-
rect setup if the receiver is replaced or is used in another aircraft.
Read the transmitter instructions for binding to a receiver (location of
transmitter’s Bind control). Please visit www.bindnfly.com for a com-
plete list of compatible transmitters.
CAUTION: When using a Futaba®transmitter with a Spektrum DSM
module, you must reverse the throttle channel and rebind. Refer to your
Spektrum module manual for binding and failsafe instructions. Refer to
your Futaba transmitter manual for instructions on reversing the throttle
channel.
1. Make sure the transmitter is powered off.
2. Move the transmitter controls to neutral (flight controls: rudder,
elevators and ailerons) or to low positions (throttle, throttle trim).**
3. Install a bind plug in the receiver bind port.
4. Connect the flight battery to the ESC. The ESC will produce a series
of sounds. 3 short tones confirm that the LVC is set correctly for the
ESC. The orange bind LED on the receiver will begin to flash rapidly.
5. Power on the transmitter while holding the transmitter bind button
or switch. Refer to your transmitter’s manual for binding.
6. 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.
7. Remove the bind plug from the bind port.
8. Safely store the bind plug (some owners attach the bind plug to their
transmitter using two-part loops and clips).
9. The receiver should retain the binding instructions received from the
transmitter until another binding is done.
* The throttle will not arm if the transmitter’s throttle control is not put at
the lowest position. If you encounter problems, follow the binding instruc-
tions and refer to the transmitter troubleshooting guide for other instruc-
tions. If needed, contact the appropriate Horizon Product Support office.
**Failsafe
If the receiver loses transmitter communication, the failsafe will activate.
When activated, the airplane controls return to the neutral position estab-
lished during step 2 of the binding procedure.

Battery Installation and ESC Arming
Battery Selection
We recommend the E-flite®1300mAh 11.1V 3S 20C Li-Po battery
(EFLB13003S20). Refer to the Optional Parts List for other recommended
batteries. If using a battery other than those listed, the battery should be within
the range of capacity, dimensions and weight of the E-flite Li-Po battery packs
to fit in the fuselage. Be sure the model balances at the recommended CG.
1. Lower the throttle and throttle trim to the lowest settings. Power on the
Transmitter, then wait 5 seconds.
2. Carefully lift the canopy hatch (B) to remove.
3. Install a fully charged battery (C) and secure it into place using the hook an
loop strap (D). See the Adjusting the Center of Gravity instructions for more
information.
4. Connect the battery to the ESC (the ESC is now armed).
• The ESC will sound a series of tones (refer to step 6 of the binding
instructions for more information).
• An LED will light on the receiver.
If the ESC sounds a continuous double beep after the flight battery is
connected, recharge or replace the battery.
5. Reinstall the canopy hatch.

CAUTION: Always
keep hands away from
the propeller. When
armed, the motor will turn
the propeller in response
to any throttle movement.

Flying Tips and Repairs
Consult local laws and ordinances before choosing a flying location.
Range Check your Radio System
Before you fly, range check the radio system. Refer to your specific transmitter
instruction manual for range test information.
Hand Launch
Set your dual rate switches to low rate. Hold the aircraft fuselage under the
wing and gradually increase the throttle to ¾. Launch the aircraft into the wind
with the wings level. Allow the aircraft to climb to a comfortable altitude.
Flying
Always choose a wide-open space for flying your aircraft. It is recommended
that you fly at a designated RC flying field. Always avoid flying near houses,
trees, wires and buildings. Avoid flying in areas where there are many people,
such as parks, schoolyards, or soccer fields.
In Flight Trimming
During your first flight, trim the aircraft for level flight at 1/2 throttle. Make
small trim adjustments with your transmitter’s trim switches to straighten the
aircraft’s flight path.
After landing, adjust the linkages mechanically to account for trim changes and
then reset the trims to neutral. Ensure the aircraft will fly straight and level
with no trim or sub-trim.
Landing
For your first flights with the recommended battery pack (EFLB13003S30), set
your transmitter timer or a stopwatch to 7 minutes. After 7 minutes, land the
aircraft. Adjust your timer for longer or shorter flights once you have flown the
model. If at any time the motor pulses, land the aircraft immediately to
recharge the flight battery. See the Low Voltage Cutoff (LVC) section for more
details on maximizing battery health and run time.
Make sure to land into the wind. Due to the high lifting efficiency of the sail-
plane design, landing requires a large landing area. While on your downwind
leg, remember that the sailplane glides much better than other aircraft. You
will need to setup for landing lower and with a more shallow descent than you
may be used to. As you are on approach for landing, ensure that the model is
descending slowly, but also not accelerating. Maintain this descent and speed,
and, as the model nears the ground (approximately 6 inches (15 cm)), slowly
apply a small amount of up elevator. Before the aircraft touches down, always
fully decrease throttle to avoid damage to the propeller, motor, ESC or other
components.
NOTICE: If a crash is imminent, reduce the throttle and
trim fully. Failure to do so could result in extra dam-
age to the airframe, as well as damage to the ESC and
motor.
NOTICE: After any impact, always ensure the receiver
is secure in the fuselage. If you replace the receiver,
install the new receiver in the same orientation as the
original receiver or damage may result.
NOTICE: Crash damage is not covered under warranty.
NOTICE: When you are finished flying, never leave the
aircraft in direct sunlight or in a hot, enclosed area
such as a car. Doing so can damage the aircraft.
Low Voltage Cutoff (LVC)
When a Li-Po battery is discharged below 3V per cell, it will not hold a charge.
The ESC protects the flight battery from over-discharge using Low Voltage
Cutoff (LVC). Before the battery charge decreases too much, LVC removes
power supplied to the motor. Power to the motor pulses, showing that some
battery power is reserved for flight control and safe landing.
Disconnect and remove the Li-Po battery from the aircraft after use to prevent
trickle discharge. Charge your Li-Po battery to about half capacity before stor-
age. During storage, make sure the battery charge does not fall below 3V
per cell. LVC does not prevent the battery from over-discharge during storage.
NOTICE: Repeated flying to LVC will damage the battery.
Tip: Monitor your aircraft battery’s voltage before and after flying by using a
Li-Po Cell Voltage Checker (EFLA111, sold separately).
Repairs
Thanks to the Z-Foam™material in this aircraft, repairs to the foam can be
made using virtually any adhesive (hot glue, regular CA, epoxy, etc). The hori-
zontal tail is not made of the same material, so use only foam-compatible
CA on the horizontal tail.
When parts are not repairable, see the Replacement Parts List for ordering by
item number. For a listing of all replacement and optional parts, refer to the list
at the end of this manual.
NOTICE: Use of CA accelerant on your aircraft can damage paint. DO NOT
handle the aircraft until accelerant fully dries.
WARNING:
Always decrease
throttle at propeller
strike.
