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.
NOTICE: Repeated flying to LVC will damage the
battery.
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.
Low Voltage Cutoff (LVC)
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. 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.

Flight Battery Installation and ESC Arming
Arming the ESC also occurs after binding as
previously described, but subsequent connection
of a flight battery requires the following steps.
It is normal for linear servos to make noise. Noise
is not an indication of a faulty servo.
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.
CAUTION: Always keep hands away
from the propeller. When armed, the motor will
turn the propeller in response to any throttle
movement.
CAUTION: Always disconnect the Li-Po
battery from the aircraft receiver 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.

The CG location is 31-37mm back from the leading
edge of the top wing.
This CG location has been determined with the
included 1S 150mAh 3.7V Li-Po battery installed
in the battery cavity located on the bottom of the
aircraft.
Balance the model on the edge of a metal ruler to
find the Center of Gravity. Place the ruler on the
underside of the airframe at the CG location shown
in the image to the right. Move the battery forward
or aft until the model closely balances at this
location. 31-37mm

Control Direction Tests
Aircraft
movement AS3X Reaction
1. Advance the throttle to 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.
ElevatorAileronRudder
Traditional Control Direction Test
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.

EN
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
For best performance with AS3X, it is important
that excessive trim is not used. If the aircraft re-
quires 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
Control Horn Settings
The table to the right shows the factory settings for
the control horns. Fly the aircraft at factory settings
before making changes.
After flying, you may choose to adjust the linkage
positions for the desired control response.
CAUTION: When these 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.
Elevator Rudder
Dual Rates
To obtain the best flight performance, we
recommend using a DSM2/DSMX radio capable
of adjustable Dual Rates. 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.

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.
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.
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.
Flying Tips and Repairs
