Battery Warnings

The included battery charger (EFLUC1007) 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

4EN4

in a temperature range of 40–120º F. Do not store 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.

• NEVER USE AN Ni-Cd OR Ni-MH CHARGER. Failure to charge the battery with a compatible charger may cause 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 safe temperature range.

• Never charge damaged batteries.

Charging the Battery

Your aircraft comes with a 2-Cell 7.4V 200mAh 25C Li-Po battery and a Celectra Charger that requires a 12V (11V-14V) DC power source.

Refer to the battery warnings. It is recommended to charge the battery pack while you are inspecting the aircraft. The ﬂ ight battery will be required to conﬁ rm proper aircraft operation in future steps.

Please visit www.horizonhobby.com for optional battery adapters.

The Battery Charging Process

1. 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.

2. The connector of the battery is speciﬁ cally designed to allow it to ﬁ t into the charge port one way to prevent reverse polarity connection. However, check for proper alignment and polarity before proceeding to the next step.

3. Gently press the battery connector into the charge port located on the front of the charger.

4. When you make the connection successfully, the green LED blinking on the charger slows, indicating proper connection.

5. Press the button on the charger. The red LED will illuminate, indicating charging has begun.

Charging a fully discharged (not over-discharged) 200mAh battery takes approximately 50–60 minutes at the charger’s 300mA charge rate. The included battery can be charged at a rate of up to 3C (600mA).

7. When the battery is fully charged, the green LED will turn solid.

8. Always unplug the battery from the charger immediately upon completion of charging.

CAUTION: Overcharging a battery can cause a ﬁ re.

Transmitter and Receiver Binding

Binding is the process of programming the receiver of the control unit to recognize the GUID (Globally Unique Identiﬁ er) code of a single speciﬁ c transmitter. You need to ‘bind’ your chosen SpektrumTM DSM2

DSMX

technology equipped aircraft transmitter to the receiver for proper operation.

™

Any JR® or Spektrum DSM2/DSMX transmitter can bind to the AS3X™ DSM® receiver. For best ﬂ ight performance of the UMX™ Gee Bee R2™, it is recommended that you use a transmitter with exponential and

dual rates. Please visit www.bindnﬂ y.com for a complete list of compatible transmitters. NOTICE: When using a Futaba® transmitter with a Spektrum DSM module, reversing the throttle channel

is required.

Binding Procedure



1. Refer to your transmitter’s unique instructions for binding to a receiver.

2. Make sure the ﬂ ight battery is disconnected from the aircraft.

3. Power off the 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 at neutral and the throttle and throttle trim are in the 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 become 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.

For subsequent ﬂ ights, power on the transmitter for 5 seconds before connecting the ﬂ ight battery.

Installing the Flight Battery

1. Remove the battery hatch.

2. Attach the flight battery to the hook and loop

strip (A) on the battery tray. See the Adjusting the Center of Gravity instructions for the battery’s position.

3. Place the aircraft on the ground out of the wind and connect a fully charged flight battery.

Ensure the aircraft is immobile for 5 seconds so the AS3X system initializes correctly. See the Arming the ESC instructions

for correct connection of the battery to the ESC.

4. Install the battery hatch.

NOTICE: If using a different battery than the recommended 2-Cell 7.4V 200mAh 25C Li-Po, you will need to apply a circle of hook and loop fastener to the battery in order to hold the battery in place.

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.

Arming the ESC

Arming the ESC also occurs after binding as previously described, but subsequent connection of a ﬂ ight battery requires the steps below.

Lower throttle and throttle trim to lowest settings.

Power on the Transmitter then wait 5 seconds

If you accidentally connect the battery while the throttle is fully raised, the ESC will enter programming mode. Disconnect the battery immediately.

The AS3X system will not activate until the throttle stick or trim is increased for the ﬁ rst time. Once the AS3X is active, the control surfaces may move rapidly on the aircraft. This is normal.

AS3X 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.

Install ﬂ ight battery and connect it to the ESC.

Keep plane immobile and away from wind for 5 seconds.

Series of tones Continuous LED

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). Before the battery charge decreases too much, LVC removes power supplied to the motor. Power to the motor quickly decreases and increases, showing that some battery power is reserved for ﬂ ight control and safe landing.

When the motor power pulses, land the aircraft immediately and recharge the ﬂ ight battery.

Disconnect and remove the Li-Po battery from the aircraft after use to prevent trickle discharge. Before storage, charge the Li-Po battery to full capacity.

During storage, make sure battery charge does not fall below 3V per cell.

Tip: Due to the quiet nature of the aircraft, you may not hear the pulsing of the motor.

For your ﬁ rst ﬂ ights, set your transmitter timer or a stopwatch to 3 minutes. Adjust your timer for longer or shorter ﬂ ights once you have ﬂ own the model. Flights of 4.5 minutes or more are achievable if using proper throttle management.

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