AS3X Stabilization Delivers Breakthrough Performance

Horizon Hobby has always made RC sport, scale and unique aircraft with the kind of performance experts appreciate. Now the exclusive Artificial Stability – 3 aXis (AS3X) system helps take performance expectations in ultra micro aircraft a quantum leap higher.

Based on the successful use of MEMS sensor technology within the AS3X Stabilization System essential to Blade helicopters, the specifically tuned AS3X System for airplanes helps invisibly correct for turbulence, torque and tip stalls when encountered.

ultra micro flybarless

Furthermore, the outstanding control agility delivers an ultra smooth, locked-in feel that obeys your every command with performance that’s natural feeling. It’s so gratifying, in fact, that it’s as though you’re the RC pilot of an expertly tuned, giant-scale model.

AS3X will change the way you’ll want to fly now and in the future. To see what we mean, go to www.E-fliteRC.com/AS3X.

Charging Warnings

The Battery Charger (EFLC1000) 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.

• 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 or (5–49° C) or place in direct sunlight.

Battery Charging

Your aircraft comes with a 1S 3.7V DC Li-Po battery charger and 1S 3.7V 150mAh 25C Li-Po battery. Refer to the charging 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.

Remove the cover on the bottom of the charger and install four of the included AA batteries, noting proper polarity. Replace the cover after the AA batteries are installed. Only use alkaline AA batteries.

Battery Charging Process

Notice: 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.

1. Slide the battery into the slot on the charger and press it into the charge jack/connector located at the bottom of the slot. The end cap of the battery is specifically designed to allow the battery to fit into the slot one way (usually with the label on the battery facing outward) to prevent reverse polarity connection. However, check for proper alignment and polarity.

Purchase the optional AC to 6V DC 1.5 amp Power Supply (EFLC1005) to charge your battery pack without AA batteries.

2. Always disconnect the flight battery from the charger immediately upon completion of charging.

CAUTION: Only use a charger speciﬁ cally designed to charge a Li-Po battery. Failure to do so could result in ﬁ re, causing injury or property damage.

CAUTION: Never exceed the recommended charge rate.

LED Indications

When you make the connection successfully, the LED on the charger turns solid red, indicating charging has begun.

Charging a fully discharged (not over-discharged) 150mAh battery takes approximately 30–40 minutes. As the battery nears full charge, the LED begins to blink. The intervals between blinks will increase as the battery comes closer to full charge.

When the LED blinks approximately every 20 seconds, the battery is ready to be removed. However, the battery can be left charging until the LED completely goes out for a maximum charge.

CAUTION: Only use an E-ﬂ ite® 6V power supply (EFLC1005) with this charger. DO NOT use a 12V power supply or property damage and injury could occur.

CHARGING (Solid Red) ...........................

READY (Blinking 20 sec. intervals) ........

MAX CHARGE (off) .................................

If the LED stays on when the ﬂ ight battery is removed, the AA batteries in the charger are low.

CAUTION: Once charging is complete, immediately remove the battery. Never leave a battery connected to the charger.

Transmitter Batteries Installation

Your E-ﬂ ite® 4-channel DSM2®/ DSMX® RTF transmitter comes pre-bound to the aircraft.

Remove the cover, install four of the included batteries (noting proper polarity) and reinstall the cover.

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™ DSM® technology equipped aircraft transmitter to the receiver for proper operation.

For a list of compatible DSM2/DSMX transmitters, please visit www.bindnﬂ y.com.

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.

Binding Procedure Reference Table



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. Ensure the transmitter is powered OFF.

4. Connect the ﬂ ight battery to the aircraft. The receiver LED will begin to ﬂ ash (typically after 5 seconds).

5. Make sure the transmitter controls are at neutral and the throttle is in the low position.

6. Put your transmitter into bind mode.

(If you are using the transmitter that is supplied with the RTF version, push the left control stick vertically into the case (until it clicks) while powering ON the transmitter).

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 end of the manual.

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

Digital Trims

The E-ﬂ ite® 4-channel DSM2/DSMX transmitter features digital trim buttons on all controls to make ﬁ ne adjustments. The digital trims are used to ﬁ ne-tune the model’s ﬂ ight path when in ﬂ ight.

Before the ﬁ rst ﬂ ight, center the control surfaces mechanically (see Control Centering). When pressed down, trim buttons make a sound that increases or decreases in pitch at each pressing. The

middle or neutral trim position is heard as a middle tone in the pitch range of the sounds. The end of the control range is sounded by a series of beeps.

Dual Rate Function

This transmitter’s dual rate feature lets you change between high and low control rates for the aileron, elevator and rudder.

• When powered ON, this transmitter is automatically set to high-rate mode.

• Change rate modes by pushing the right-hand control stick vertically into the case (until it clicks) while the transmitter is powered ON.

• High-rate mode is shown by the transmitter’s LED glowing solid red. In high-rate mode, the controls can reach their maximum values. This mode is typically preferred by experienced pilots for maximum control authority.

• Low-rate mode is shown by the transmitter’s LED blinking continuously. In low-rate mode, the controls are reduced to approximately 70% of their maximum values. This mode is typically preferred by (and best for) beginner pilots or others interested in smoother and more easily controlled ﬂ ight.
