Safety Precautions and Warnings
• Always keep a safe distance in all directions
around your model to avoid collisions or injury.
This model is controlled by a radio signal subject
to interference from many sources outside your
control. Interference can cause momentary loss
of control.
• Always operate your model in open spaces away
from full-size vehicles, traffic and people.
• Always carefully follow the directions and
warnings for this and any optional support equipment (chargers, rechargeable battery packs, etc.).
• Always keep all chemicals, small parts and
anything electrical out of the reach of children.
• Always avoid water exposure to all equipment
not specifically designed and protected for this
purpose. Moisture causes damage to electronics.
• Never place any portion of the model in your
mouth as it could cause serious injury or
even death.
• Never operate your model with low transmitter
batteries.
• Always keep aircraft in sight and under control.
• Always use fully charged batteries.
• Always keep the transmitter powered on while
aircraft is powered.
• Always remove batteries before disassembly.
• Always keep moving parts clean.
• Always keep parts dry.
• Always let parts cool after use before touching.
• Always remove batteries after use.
• Always ensure failsafe is properly set
before flying.
• Never operate aircraft with damaged wiring.
• Never touch moving parts.

Transmitter and Receiver Binding
For subsequent flights, power ON the transmitter for 5 seconds before connecting the flight battery.
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. Ensure the transmitter is powered OFF.
4. Connect the flight battery to the aircraft and turn the aircraft upright. The receiver LED will begin to
flash (typically after 5 seconds).
5. Ensure that control surface trims are centered and the throttle and throttle trims are in the low
position to correctly set the failsafe.
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.
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
aircraft.
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.
NOTICE: Repeated flying to LVC will damage the
battery.

NOTICE: Always keep material or debris away
from the intake. When armed, the rotor will turn in
response to throttle movement and could ingest in
any loose objects.
Arming the ESC/receiver also occurs after binding
as previously described, but subsequent connection
of a flight battery requires the following steps.
1. Lower the throttle and throttle trim to the
lowest settings on your transmitter.
2. Remove the battery/canopy hatch from the
fuselage and install a flight battery (A) all the
way to the back of the battery comportment.
Center of Gravity (CG)
The CG location is 34-36mm back from the leading
edge of the wing at the root. Balance the airplane
inverted on this recommended CG mark with all
landing gear installed. Adjust as needed by sliding
the battery forward or back.
3. Power on your transmitter, then
wait 5 seconds.
4. Connect the battery to the ESC, noting proper
polarity. Keep the plane immobile and away
from wind for 5 seconds to allow the AS3X
system to initialize.
A successful connection is indicated by:
– A series of tones
– A continuous LED
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.

Before the first flights, or in the event of an
accident, make sure control surfaces are
centered when the transmitter controls and
trims are neutral. The transmitter sub-trim must
be set to zero. 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.
• Make the U-shape narrower to make the
connector shorter. Make the U-shape wider to
make the linkage longer.
• Ensure that the leading edge of both the
horizontal stabilizers are 1mm above the lower
edge of the side panel, as shown in the image to
the right.

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.
Rudder Ailerons Elevator
Dual Rates and Expos
To obtain the best flight performance, we
recommend using a DSM2/DSMX transmitter
capable of Dual Rates and Expo. Before binding,
ensure that you are starting with a blank acro
model in your transmitter. Set wing type and servo
reversing to normal.
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 landing, we recommend using high rate
elevator.
