Charger Warnings

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.

• 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.

(off) ...................................

• 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 leave charging batteries unattended.

• 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.

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) 250mAh battery takes approximately 40 minutes at the charger’s 300mA charge rate.

Transmitter and Receiver Binding

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 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.

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.

DSM2/DSMX technology

Low Voltage Cutoff (LVC)

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.

1-2-3-4-5 Sec.

ESC/Receiver Arming, Battery Installation and Center of Gravity

CAUTION: Always keep hands away from the

propellers. When armed, the motors 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 ﬂ ight battery requires the following steps.

AS3X

The AS3X 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. Attach the battery to the hook and loop strip so

system will not activate until the

the battery is as far forward as the hatch will allow.

Center of Gravity (CG)

At the wing root, measure the CG location 37mm back from the forward-most leading edge of the top wing.

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 plane immobile and away from wind for 5 seconds to allow the AS3X system to initialize. A continuous LED indicates a successful connection.

37mm

CAUTION: Always disconnect the Li-Po battery from the ESC when not ﬂ ying 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 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.
