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. 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.

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.

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 29mm back from the leading
edge at the wing root.
This CG location has been determined with the
included 1S 150mAh 3.7V Li-Po battery installed
towards the rear of 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.

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

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
requires 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.
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.
