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 fire, 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 fire.
• 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 40–120°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 fire.

• 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.

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 flight battery will be required to confirm 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.
2. Always disconnect the flight battery from the charger immediately upon completion of charging.

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

CAUTION: Never exceed the recommended e 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.

BNF

Transmitter and Receiver Binding

BIND-N-FLY\*

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 e 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.

Digital Trims

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

Before the first flight, 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 flight.

Flight Battery Installation and ESC Arming

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

AS3X

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.

It is normal for linear servos to make noise. Noise is not an indication of a faulty servo.

CAUTION: Always keep hands away the propeller. When armed, the motor will be propeller in response to any throttle ment.

CAUTION: Always disconnect the Li-Po rty from the aircraft receiver when not g to avoid over-discharging the battery. ries discharged to a voltage lower than west approved voltage may become ged, resulting in loss of performance and tial fi re when batteries are charged.

The CG location is 28mm 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 in the battery cavity.

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.

28mm

Control Direction Test

Bind your aircraft and transmitter before doing these tests. Move the controls on the transmitter to make sure aircraft control surfaces move correctly. Always keep throttle at the low position during testing.

Control Centering

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.

Diagram of a tool interacting with a mechanical component, showing a handle and base (no text or symbols)

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 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 fl ying, you may choose to adjust the linkage positions for the desired control response.

CAUTION: When these are incorrectly subjected for the pilot's skill level, unexpected shift response to controls can result. This can be damage to the aircraft and personal injury.

Aileron Elevator Rudder

Dual Rates

To obtain the best fl ight 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 fl ight.

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 signifi cant noise. The noise is not an indication of a faulty servo.

	Dual Rate
	High Low
Aileron 100%	70%
Elevator 100%	70%
Rudder 100%	70%

Tip: For the first flight, fly the model in low rate.

Flying Tips and Repairs

We recommend fl ying your aircraft outside in calm conditions. Always avoid fl ying near houses, trees, wires and buildings. You should also be careful to avoid fl ying in areas where there are many people, such as busy parks, schoolyards or soccer fi elds. Consult local laws and ordinances before choosing a location to fl y your aircraft.

a location to fly your aircraft.

Takeoff

Place the aircraft in position for takeoff (facing into the wind if fl ying outdoors). Set dual rates to low position and gradually increase the throttle to 34 to full and steer with the rudder. Pull back gently on the elevator and climb to check trim. Once the trim is adjusted, begin exploring the fl ight envelope of the aircraft.

Landing

Land into the wind. This is very important for this model. Fly the aircraft to approximately 6 inches (15cm) or less above the runway, using a small amount of throttle for the entire descent. Keep the throttle on until the aircraft is ready to fl are. During fl are, keep the wings level and the airplane pointed into the wind. Gently lower the throttle while pulling back on the elevator to bring the aircraft down on all three wheels.

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 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 pulses, land the aircraft immediately and replace or recharge the flight battery.

Failure to lower the throttle stick and trim to the lowest possible positions during a crash could result in damage to the ESC in the receiver unit, which may require replacement.

This aircraft is equipped with Over Current Protection (OCP). This feature protects the ESC from overheating. OCP stops the motor when the transmitter throttle is set too high and the propeller cannot turn. The OCP will only activate when the throttle stick is positioned just above 1/2 throttle. After the ESC stops the motor, fully lower the throttle to re-arm the ESC.

NOTICE: Crash damage is not covered under the warranty.

Repairs

Repair the aircraft using foam-compatible CA (cyanoacrylate adhesive) or clear tape. Only use foam-compatible CA, as other types of glue can damage the foam. When parts are not repairable, see the Replacement Parts List for ordering by item number.

For a listing of all replacement and optional parts, refer to the list at the end of this manual.

NOTICE: Use of foam-compatible CA accelerant on your aircraft can damage paint. DO NOT handle the aircraft until the accelerant fully dries.

NOTICE: When you are fi nished fl ying, never leave the aircraft in direct sunlight or in a hot, enclosed area such as a car. Doing so can damage the foam.

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 lights, set your transmitter timer or a stopwatch to 4 minutes. Adjust your timer for longer or shorter lights once you have flown the model.

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

NOTICE: Always decrease throttle at propeller strike.
