Preflight Checklist
9
1. Charge flight battery.
2. Install flight battery in aircraft
(once it has been fully
charged).
3. Bind aircraft to transmitter.
4. Make sure linkages move
freely.
5. Perform Control Direction
Test with transmitter.
6. Adjust center of gravity.
7. Perform a radio system
Range Check.
8. Find a safe and open area.
9. Plan flight for flying field
conditions.
Low Voltage Cutoff (LVC)
When a Li-Po battery is discharged below 3V per cell, it
will not hold a charge. The aircraft’s ESC protects the flight
battery from over-discharge using Low Voltage Cutoff (LVC).
Once the battery discharges to 3V per cell, the LVC will
reduce the power to the motor in order to leave adequate
power to the receiver and servos to land the airplane.
When the motor power decreases, land the aircraft
immediately and replace or recharge the flight battery.
Always disconnect and remove the Li-Po battery from the
aircraft after each flight. Charge your Li-Po battery to about
half capacity before storage. Make sure the battery charge
does not fall below 3V per cell. Failure to unplug a connected
battery will result in trickle discharge.
For your first flights, set your transmitter timer or a stopwatch
to 5 minutes. Adjust your timer for longer or shorter flights
once you have flown the model. Flights of 7 minutes are
achievable if using proper throttle management.
NOTICE: Repeated flying to LVC will damage the battery.
9Binding Procedure
1. Refer to your transmitter’s unique instructions for binding to a
receiver (location of transmitter’s Bind control).
2. Make sure the flight battery is disconnected from the aircraft.
3. Power off the transmitter.
4. Bind the AR6310 receiver to a DSM2 transmitter by shorting
the bind pins (A) with tweezers, a hemostat or small needle-
nose pliers. Metal to metal contact is needed to complete the
circuit. Do not bend the bind pins.
5. Put your transmitter into bind mode. Refer to your transmit-
ter’s manual for binding button or switch instructions.
6. Ensure that control surface trims are centered and the throttle
and throttle trims are in the low position to correctly set the
failsafe.
7. Connect the flight battery to the aircraft. Short the pins until
the receiver LED begins to flash rapidly (typically after 5
seconds).
8. After 5 to 10 seconds, the receiver status LED will become
solid, indicating that the receiver is bound to the transmitter. If
the LED does not turn solid, refer to the Troubleshooting Guide
at the back of the manual.
Binding is the process of programming the receiver
of the control unit 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.
Any full range Spektrum DSM2/DSMX transmitter can bind to
the DSM2/DSMX receiver. Please visit www.bindnfly.com for a
complete list of compatible transmitters.
Transmitter and Receiver Binding
A
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 instruct-
ions. Refer to your Futaba transmitter
manual for instructions on reversing the
throttle channel.

Installing the Flight Battery
1. Remove the battery hatch from the nose of
the aircraft.
2. Apply the included strip of hook and loop
tape to the bottom of your battery near the
battery leads. This position allows easier
battery installation and removal.
3. For the recommended CG, install the battery
fully forward in the compartment (against the
firewall), then press the battery onto the hook
and loop strip (A). See the Adjusting the Center
of Gravity instructions for more information.
4. Connect a fully charged flight battery to the
ESC. See the Arming the ESC instructions for
correct connection of the battery to the ESC.
5. Reinstall the battery hatch.
CAUTION: Always disconnect the Li-Po
battery from the ESC when not flying to eliminate
power supplied to the motor. The ESC does not have
an arming switch and will respond to any
transmitter input when a signal is present.
CAUTION: Always disconnect the Li-Po
battery from the ESC when not flying 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 fire when batteries
are charged.

EN
Arming the ESC
Arming the ESC also occurs after binding as
previously described, but subsequent connection of
a flight battery requires the steps below.
Tip: If the ESC sounds a continuous double beep
after the flight battery is connected, recharge or
replace the battery.
If you accidentally connect the battery while the
throttle is fully opened, a musical tone will sound
after 5 seconds and the ESC will enter programming
mode. Disconnect the battery immediately.
CAUTION: Always keep hands away from the
propeller. When armed, the motor will turn the
propeller in response to any throttle movement.
Lower throttle and throttle trim to lowest
settings.
Power on the Transmitter.

Remove the magnetic battery hatch and
install the flight battery to the hook and
loop strip, then connect the battery to the
ESC, noting proper polarity.

1. Slide the wing tube into the right wing.
2. Insert the right wing with the wing tube (A)
into the round hole in the wing slot of
the fuselage while connecting the right
aileron control.
NOTICE: When disconnecting the servo
connectors, do not pull on the servo wires.
Use a screwdriver or pliers to break the friction
fit of the servo connectors. Failure to do so
could result in damage to the servo wiring.
3. Install the left wing (B) by sliding it over
the wing tube to the fuselage while
connecting the left aileron control.
4. Invert the fuselage so the landing gear is
facing up. Secure the left and right wing to
the fuselage using the included screws (C).
6. Remove the screw (D) and the receiver
cover (E) from the bottom of the fuselage.
7. Connect the aileron servos in the wings
to the Y-harness connectors in the
fuselage. The left and right aileron
servos can be connected to either side
of the Y-harness.
Tip: If you are using dual aileron/flaperon
transmitter programming, connect the aileron
servo connectors to the AILE and AUX1 ports on
the receiver instead of using the
included Y-harness.
After connecting the servos to the separate
ports, program your transmitter for dual aileron/
flaperon and differential to benefit from the high
performance characteristics of this aircraft.

Before the first flights, or in the event of an
accident, make sure the flight control surfaces
are centered. Adjust the linkages mechanically if
the control surfaces are not centered. Use of the
transmitter sub-trims may not correctly center the
aircraft control surfaces due to the mechanical
limits of linear servos.
1. Make sure the control surfaces are neutral
when the transmitter controls and trims are
centered. The transmitter sub-trim must
always be set to zero.
2. When needed, use a pair of pliers to carefully
bend the metal linkage (see illustration).
3. Make the U-shape narrower to make the
connector shorter. Make the U-shape wider
to make the linkage longer.
Centering Controls After First Flights
If the model requires excessive transmitter trim
(4 or more clicks of trim per channel), return the
transmitter trim to zero and adjust the linkages
mechanically so that the control surfaces are in the
flight trimmed position.
Control Centering
Settings for Servo Arms
The following illustration shows the factory settings
for linkages on the servo arms. After flying, you
may choose to adjust the linkage positions for the
desired control response.
Control Direction Test
You should bind your aircraft and transmitter
before doing these tests. Move the controls on
the transmitter to make sure the aircraft control
surfaces move correctly and in the proper direction.
Make sure the tail linkages move freely and that
paint or decals are not adhered to them.

EN
Dual Rates and Expos
We recommend using a DSM radio capable
of dual rates and expo. The settings below are
recommended starting settings for intermediate
pilots. Adjust according to individual preferences
after the initial flight.
Tip: For the first flight, fly the model at LOW RATE.

Adjusting Center of Gravity (CG)
The CG location is 40-42mm back from the leading
edge of the wing at the root.
The battery cavity is oversized to allow for Center
of Gravity adjustment. Start by placing the
battery fully forward against the firewall with the
connectors facing the rear of the aircraft. Adjust as
needed by sliding the battery back.
40-42mm
Applying Decals
Customize your aircraft by applying water-based
number decals (A) on both sides of the fuselage.
1. Ensure the fuselage is clean.
2. Cut around the desired numbers on the
decal sheet.
3. Soak the decals in water for 10 to 15 seconds.
4. Wet the fuselage with water, then move each
decal from the backing to the fuselage.
5. Pat each decal dry with a towel to
remove bubbles.
6. Allow the decals to dry.
