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.
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 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
: Tail > Normal
3. Leave all settings at their default values.
The Gear Switch (ch 5) will control the Safe mode function.
• Switch position 0 = SAFE Mode
• Switch position 1 = AS3X Mode

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.

ESC/Receiver Arming, Battery Installation and Center of Gravity
28mm
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.
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.

Aircraft movement AS3X Reaction
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.

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

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.
Low Voltage CutOff

EN
Post Flight Checklist
1. Disconnect the flight battery from the ESC
(Required for safety and battery life).
2. Power OFF the transmitter.
3. Remove the flight battery from the aircraft.
4. Recharge the flight battery.
5. Store the flight battery apart from the aircraft and
monitor the battery charge.
6. Make note of the flight conditions and flight plan
results, planning for future flights.
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.
