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.
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
Binding Procedure
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. 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 your transmitter.
4. Set the aircraft upright on its wheels and connect the flight battery in the aircraft. The receiver LED
will begin to flash rapidly (typically after 5 seconds)
5. Make sure the transmitter controls are neutral and the throttle and throttle trim are in low position.
6. Put your transmitter into bind mode. Refer to your transmitter’s manual for binding button or switch
instructions.
7. After 5 to 10 seconds, the receiver status LED will turn 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.
For subsequent flights, power ON the transmitter for 5 seconds before connecting the flight battery.
SAFE®Select Technology
The evolutionary SAFE®Select technology can offer an extra level of protection so you can perform the first
flight with confidence. No complex transmitter programming is required. Just simply flip your GEAR switch
(Channel 5) to position 0 to make the SAFE Select system active. Flip the Gear switch to position 1 to turn
OFF SAFE Select and fly with just the assistance of AS3X.
When activated, bank and pitch limitations keep you from over-controlling and automatic self-leveling
makes recovery from risky or confusing attitudes as simple as releasing the sticks. In fact, with the aileron,
elevator and rudder sticks in the neutral position, SAFE Select will automatically keep the airplane in a
straight and level attitude.
Expand the advantage of what SAFE®Select technology offers by assigning it to a switch. No transmitter
programming is required and you’ll be able to turn the system ON and OFF with the flip of a switch. For ex-
ample, turn SAFE select ON for takeoffs for worry free takeoffs. Turn it OFF in flight for unrestricted aerobatic
performance, and turn it back ON when a buddy wants to try out your cool aircraft. Turn SAFE Select ON for
landings, SAFE Select reduces your work load by compensating for pitch changes automatically, regard-
less of throttle position. It will help keep the correct pitch attitude and wings level during the final approach.
Whether you’re a beginner or an expert, SAFE Select can make your flights a great experience.
When the SAFE Select system is turned OFF it leaves the specially tuned AS3X®technology in place to
deliver a pure, unrestricted flight experience.

LVC is a feature built into your ESC to protect the
battery from over-discharge. When the battery
charge becomes too low, LVC limits power supplied
to the motor. When you hear the motor power pulse,
land the aircraft immediately and recharge the flight
battery.
NOTICE: Do not rely on LVC to determine when
to land your aircraft. Set a flight timer to the
recommended flight time. Repeated flying to LVC
will damage the battery.
Low Voltage Cutoff (LVC)
IMPORTANT: After you set up your model,
always rebind the transmitter and receiver
to set the desired failsafe positions.
Program Your Transmitter
1. Start with a clean model memory slot.
2. Set the model type to “Airplane.”
3. Leave all settings at their default values.
Switch A will now control the flight mode
function.
• Switch position 0 = SAFE Mode
• Switch position 1 = AS3X Mode

ESC/Receiver Arming, Battery Installation and Center of Gravity
CAUTION: Always keep hands away from the
propeller. When armed, the motor will turn the
propeller in response to any throttle movement.
Arming the ESC/receiver also occurs after binding
as previously described, but subsequent connection
of a flight battery requires the following steps.
AS3X
The AS3X®system will not activate until the
throttle stick or trim is increased for the first
time. Once active, the control surfaces may
move rapidly and noisily on the aircraft.
This is normal. AS3X technology will remain
active until the battery is disconnected.
1. Open the battery hatch located at the bottom of
the fuselage.
2. Install the flight battery in the center of battery
try. Ensure the battery is secured by the hook
and loop strip.
Center of Gravity (CG)
Measure back 39mm from the leading edge of the
wing, where the wing meets the fuselage and place
a mark. Balance the airplane on this CG mark.
3. Lower the throttle and throttle trim to the
lowest settings on your transmitter. Power
on your transmitter, then wait 5 seconds.
4. Connect the battery to the ESC, noting proper
polarity. Keep the aircraft upright (on its gear)
and immobile and away from wind for 5
seconds to allow the AS3X system to initialize.
A series of tones and a continuous LED
indicates a successful connection.
Every time the receiver is powered ON the
control surfaces will cycle back and forth
twice with a slight pause at neutral position to
indicate that SAFE Select is switched ON.
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.

Control Direction Tests
Aircraft
movement AS3X Reaction
1. Flip the Gear Switch to put
aircraft into SAFE mode.
2. Fully lower the throttle.
3. 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 fly 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
is active until the battery is
disconnected.

Traditional 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.
AS3X®/SAFE®Control Direction Test
This test is meant to check that the AS3X®system is functioning properly.

EN
Before your first flight make sure the aircraft’s
control surfaces are centered.
1. Power on the transmitter and then the aircraft.
2. Set all transmitter trims and sub-trims to zero.
3. Check the control surfaces to make sure they
are centered.
4. If centering is required, use a pair of pliers to
carefully bend the metal linkage
(see illustration).
In flight trimming may be required
During your first flight, the aircraft should fly
straight and level. Use your transmitter trims to fine
tune the aircraft’s flight path until its flight path has
been corrected. Any transmitter trim that requires
4 or more clicks of trim (per channel), should be
mechanically centered. Note the control surface’s
postion and return the transmitter trim to zero.
Adjust the linkages mechanically so that the control
surfaces are in the flight trimmed position.
Control Centering
Factory Control Horn Settings
The illustration shows the factory settings for
linkages on the control horns. Linkage connections
on the control horns directly affect aircraft response.
CAUTION: When the control horns and
arms are incorrectly connected for the
pilot’s skill level, unexpected aircraft response to
controls can result. This can cause damage to the
aircraft and personal injury.
Aileron Elevator Rudder
Make the U-shape narrower to make the
connector shorter. Make the U-shape wider to
make the linkage longer.

EN
We recommend flying your aircraft outside in calm
conditions. Always avoid flying near houses, trees,
wires and buildings. You should also be careful to
avoid flying in areas where there are many people,
such as busy parks, schoolyards or soccer fields.
Consult local laws and ordinances before choosing
a location to fly your aircraft.
Takeoff
Place the aircraft in position for takeoff (facing into
the wind if flying outdoors). Gradually increase the
throttle to ¾ to full and steer with the rudder. Pull
back gently on the elevator and climb to check trim.
Once the trim is adjusted, begin exploring the flight
envelope of the aircraft.
Landing
Land into the wind. This is very important for this
model. Fly the aircraft to approximately 6 inches
(15cm) or less above the runway, using a small
amount of throttle for the entire descent. Keep the
throttle on until the aircraft is ready to flare.
During flare, keep the wings level and the airplane
pointed into the wind. Gently lower the throttle while
pulling back on the elevator to bring the aircraft
down on all three wheels.
Failure to lower the throttle
stick and trim to the lowest
possible positions during a
crash could result in damage
to the ESC in the receiver
unit, which may require
replacement.
Over Current Protection
(OCP)
This aircraft is equipped with
Over Current Protection (OCP).
This feature protects the ESC
from overheating. OCP stops
the motor when the transmitter throttle is set too
high and the propeller cannot turn. The OCP will
only activate when the throttle stick is positioned
just above 1/2 throttle. After the ESC stops the
motor, fully lower the throttle to re-arm the ESC.
NOTICE: Crash damage is not covered under the
warranty.
Repairs
Repair the aircraft using foam-compatible CA
(cyanoacrylate adhesive) or clear tape. Only use
foam-compatible CA, as other types of glue can
damage the foam. 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 foam-compatible CA accelerant
on your aircraft can damage paint. DO NOT handle
the aircraft until the accelerant fully dries.
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 foam.
