not specifi cally 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.

The battery charger (EFLC1008) included with your
aircraft has been designed to safely charge the
Li-Po battery.

CAUTION: All instructions and warnings must

be followed exactly. Mishandling of Li-Po
batteries can result in a fi re, personal injury and/or
property damage.

• Never leave charging batteries unattended.

• Never charge batteries overnight.

• By handling, charging or using the included Li-Po

battery, you assume all risks associated with
lithium batteries.

• If at any time the battery begins to balloon or

swell, discontinue use immediately. If charging
or discharging, discontinue and disconnect.
Continuing to use, charge or discharge a battery
that is ballooning or swelling can result in fi re.

• Always store the battery at room temperature in a

dry area for best results.

• Always transport or temporarily store the battery

in a temperature range of 40–120º F (5–49° C).
Do not store the battery or model in a car or direct
sunlight. If stored in a hot car, the battery can be
damaged or even catch fi re.

• Always charge batteries away from fl ammable
materials.

• Always inspect the battery before charging.

• Always disconnect the battery after charging, and
let the charger cool between charges.

• Always constantly monitor the temperature of the
battery pack while charging.

• ONLY USE A CHARGER SPECIFICALLY DESIGNED
TO CHARGE LI-PO BATTERIES. Failure to charge
the battery with a compatible charger may cause
a fi re resulting in personal injury and/or property
damage.

• Never discharge Li-Po cells to below 3V under
load.

• Never cover warning labels with hook and loop
strips.

• Never charge batteries outside recommended
levels.

• Never charge damaged batteries.

• Never attempt to dismantle or alter the charger.

• Never allow minors to charge battery packs.

• Never charge batteries in extremely hot or cold
places (recommended between 40–120° F (5–49°
C)) or place in direct sunlight.

Charger Warnings

CAUTION: Never exceed the recommended

charge rate.

CAUTION: Charge only batteries that are cool
to the touch and are not damaged. Look at the
battery to make sure it is not damaged e.g.,
swollen, bent, broken or punctured.

CAUTION: Always disconnect the fl ight
battery from the charger immediately upon
completion of charging.

Charging a fully discharged (not over-discharged)
150mAh battery takes approximately 45 minutes at
the charger’s 300mA charge rate.

When a Li-Po battery is discharged below 3V per
cell, it will not hold a charge. The aircraft’s ESC
protects the fl ight 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 fl ight
battery.

Always disconnect and remove the Li-Po battery

from the aircraft after each fl ight. 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 fi rst fl ights, set your transmitter timer or a
stopwatch to 5 minutes. Adjust your timer for longer
or shorter fl ights once you have fl own the model.

NOTICE: Repeated fl ying to LVC will damage the
battery.

Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifi er)
code of a single specifi c 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.

bindnfl y.com for a complete list of compatible transmitters.

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 fl ight battery is disconnected from the aircraft.

3. Power off your transmitter.

4. Connect the fl ight battery in the aircraft. The receiver LED will begin to fl ash 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 fl ight 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 fi rst
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
fl ying 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 fi re 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
fi nd 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.
