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
9Binding 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 to position 1 (Channel 5) to make the SAFE Select system active. Flip the Gear switch back to
turn OFF SAFE Select and fly with just the assistance of AS3X®technology.
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.

EN
To obtain the best flight performance, we recommend using a DSM2®/
DSMX®transmitter capable of Dual Rates. Before binding, ensure that
you are starting with a blank acro model in your transmitter.
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 new ACRO Model.
2. Set Aircraft Type: Wing >1Ail 1Flap

Dual Rates and Expos
The suggested settings shown here are the recommended
starting settings. Adjust according to the individual preferences
after the initial flight.
NOTICE: Do not set your transmitter travel adjust over 100%.
If the TRAVEL ADJUST is set over 100%, it will not result in more
control movement, it will overdrive the servo and cause damage.
It is normal for linear servos to make significant noise. The noise
is not an indication of a faulty servo.
Tip: For the first flight, fly the model in low rate.

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. Remove the battery hatch from the fuselage.
2. Install the flight battery in the center of the
battery tray. Ensure the battery is secured by
the hook and loop strip.
Center of Gravity (CG)
Measure back 28mm from the leading edge of the
top wing, where the wing meets the fuselage and
place a mark. Balance the airplane on this CG mark.
The easiest way to achieve CG is to balance the
aircraft upright.
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.
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.

1. Advance the throttle above
25% to activate the AS3X
system.
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.

AS3X®Control Direction Test
This test ensures that the AS3X®control system is functioning properly.
Control Direction Tests
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.

Control Centering
Control Horn Settings
The illustration shows linkage positions chosen for
the best aerobatic response. Linkage connections
on the control horns directly affect aircraft response.
Aileron RudderElevator
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 it 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.
Make the U-shape narrower to make the
connector shorter. Make the U-shape wider to
make the linkage longer.
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.

Flying Tips and Repairs
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). Set dual rates to low
position and 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.
CAUTION:
Always decrease
throttle at propeller
strike.
