Transmitter and Receiver Binding

Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifier) code of a single specific transmitter. You need to 'bind' your chosen Spektrum™ DSM2®/DSMX® technology equipped aircraft transmitter to the receiver for proper operation.

IMPORTANT: Before binding a transmitter, read the Transmitter Setup section of this manual to ensure that your transmitter is properly programmed for this aircraft.

IMPORTANT: The included AR400 receiver has been programmed for operation specifi cally for this aircraft. Refer to the receiver manual for cor-rect setup if the receiver is replaced or is used in another aircraft.

Read the transmitter instructions for binding to a receiver (location of transmitter's Bind control). Please visit www.bindnfl y.com for a com-plete list of compatible transmitters.

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. Make sure the transmitter is powered off.

2. Move the transmitter controls to neutral (fl ight controls: rudder, elevators and ailerons) or to low positions (throttle, throttle trim).**

3. Install a bind plug in the receiver bind port.

4. Connect the fl ight battery to the ESC. The ESC will produce a series of sounds. 3 short tones confi rm that the LVC is set correctly for the ESC. The orange bind LED on the receiver will begin to fl ash rapidly.

5. Power on the transmitter while holding the transmitter bind button or switch. Refer to your transmitter's manual for binding.

6. When the receiver binds to the transmitter, the orange bind light on the receiver will turn solid and the ESC will produce ascending tones. The tones indicate the ESC is armed, provided the throttle stick and throttle trim are low enough to trigger arming.

7. Remove the bind plug from the bind port.

8. Safely store the bind plug (some owners attach the bind plug to their transmitter using two-part loops and clips).

9. The receiver should retain the binding instructions received from the transmitter until another binding is done.

* The throttle will not arm if the transmitter's throttle control is not put at the lowest position. If you encounter problems, follow the binding instructions and refer to the transmitter troubleshooting guide for other instructions. If needed, contact the appropriate Horizon Product Support offi ce.

\*\*Failsafe

If the receiver loses transmitter communication, the failsafe will activate. When activated, the airplane controls return to the neutral position established during step 2 of the binding procedure.

Battery Installation and ESC Arming

Battery Selection

We recommend the E-fl ite® 1300mAh 11.1V 3S 20C Li-Po battery (EFLB13003S20). Refer to the Optional Parts List for other recommended batteries. If using a battery other than those listed, the battery should be within the range of capacity, dimensions and weight of the E-fl ite Li-Po battery packs to fit in the fuselage. Be sure the model balances at the recommended CG.

1. Lower the throttle and throttle trim to the lowest settings. Power on the Transmitter, then wait 5 seconds.
2. Carefully lift the canopy hatch (B) to remove.
3. Install a fully charged battery (C) and secure it into place using the hook and loop strap (D). See the Adjusting the Center of Gravity instructions for more information.
4. Connect the battery to the ESC (the ESC is now armed).

- The ESC will sound a series of tones (refer to step 6 of the binding instructions for more information).

- An LED will light on the receiver.

If the ESC sounds a continuous double beep after the flight battery is connected, recharge or replace the battery.

1. Reinstall the canopy hatch.

Flying Tips and Repairs

Consult local laws and ordinances before choosing a fl ying location.

Range Check your Radio System

Before you fly, range check the radio system. Refer to your specific transmitter instruction manual for range test information.

Hand Launch

Set your dual rate switches to low rate. Hold the aircraft fuselage under the wing and gradually increase the throttle to 34 . Launch the aircraft into the wind with the wings level. Allow the aircraft to climb to a comfortable altitude.

Diagram illustrating wind-induced aircraft movement with a person carrying an airplane and wind direction indicated by arrows

Flying

Always choose a wide-open space for fl ying your aircraft. It is recommended that you fl y at a designated RC fl ying fi eld. Always avoid fl ying near houses, trees, wires and buildings. Avoid fl ying in areas where there are many people, such as parks, schoolyards, or soccer fi elds.

In Flight Trimming

During your fi rst fl ight, trim the aircraft for level fl ight at 1/2 throttle. Make small trim adjustments with your transmitter's trim switches to straighten the aircraft's fl ight path.

After landing, adjust the linkages mechanically to account for trim changes and then reset the trims to neutral. Ensure the aircraft will fly straight and level with no trim or sub-trim.

Landing

For your fi rst fl ights with the recommended battery pack (EFLB13003S30), set your transmitter timer or a stopwatch to 7 minutes. After 7 minutes, land the aircraft. Adjust your timer for longer or shorter fl ights once you have fl own the model. If at any time the motor pulses, land the aircraft immediately to recharge the flight battery. See the Low Voltage Cutoff (LVC) section for more details on maximizing battery health and run time.

Make sure to land into the wind. Due to the high lifting efficiency of the sailplane design, landing requires a large landing area. While on your downwind leg, remember that the sailplane glides much better than other aircraft. You will need to setup for landing lower and with a more shallow descent than you may be used to. As you are on approach for landing, ensure that the model is descending slowly, but also not accelerating. Maintain this descent and speed, and, as the model nears the ground (approximately 6 inches (15 cm)), slowly apply a small amount of up elevator. Before the aircraft touches down, always fully decrease throttle to avoid damage to the propeller, motor, ESC or other components.

NOTICE: If a crash is imminent, reduce the throttle and trim fully. Failure to do so could result in extra damage to the airframe, as well as damage to the ESC and motor.

NOTICE: After any impact, always ensure the receiver is secure in the fuselage. If you replace the receiver, install the new receiver in the same orientation as the original receiver or damage may result.

NOTICE: Crash damage is not covered under warranty.

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 aircraft.

Low Voltage Cutoff (LVC)

When a Li-Po battery is discharged below 3V per cell, it will not hold a charge. The ESC protects the fl light 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 pulses, showing that some battery power is reserved for fl light control and safe landing.

Disconnect and remove the Li-Po battery from the aircraft after use to prevent trickle discharge. Charge your Li-Po battery to about half capacity before storage. During storage, make sure the battery charge does not fall below 3V per cell. LVC does not prevent the battery from over-discharge during storage.

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

Tip: Monitor your aircraft battery's voltage before and after fl ying by using a Li-Po Cell Voltage Checker (EFLA111, sold separately).

Repairs

Thanks to the Z-Foam™ material in this aircraft, repairs to the foam can be made using virtually any adhesive (hot glue, regular CA, epoxy, etc). The horizontal tail is not made of the same material, so use only foam-compatible CA on the horizontal tail.

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 CA accelerant on your aircraft can damage paint. DO NOT handle the aircraft until accelerant fully dries.

Post Flight

1	Disconnect the fl ight battery from the ESC (Required for Safety and battery life).
2	Power OFF the transmitter.
3	Remove the fl ight battery from the aircraft.
4	Recharge the fl ight battery.

5	Repair or replace all damaged parts.
6	Store the fl ight battery apart from the aircraft and monitor the battery charge.

Questions, Assistance, and Services

Your local hobby store and/or place of purchase cannot provide warranty support or service. Once assembly, setup or use of the Product has been started, you must contact your local distributor or Horizon directly. This will enable Horizon to better answer your questions and service you in the event that you may need any assistance. For questions or assistance, please visit our website at www.horizonhobby.com, submit a Product Support Inquiry, or call the toll free telephone number referenced in the Warranty and Service Contact Information section to speak with a Product Support representative.

Warranty Requirements

For Warranty consideration, you must include your original sales receipt verifying the proof-of-purchase date. Provided warranty conditions have been met, your Product will be serviced or replaced free of charge. Service or replacement decisions are at the sole discretion of Horizon.

Non-Warranty Service

Should your service not be covered by warranty, service will be completed and payment will be required without notification or estimate of the expense unless the expense exceeds 50% of the retail purchase cost. By submitting the item for service you are agreeing to payment of the service without notification. Service estimates are available upon request. You must include this request with your item submitted for service. Non-warranty service estimates will be billed a minimum of 12 hour of labor. In addition you will be billed for return freight. Horizon accepts money orders and cashier's checks, as well as Visa, MasterCard, American Express, and Discover cards. By submitting any item to Horizon for service, you are agreeing to Horizon's Terms and Conditions found on our website http://www.horizonhobby.com/content/_service-center_render-service-center.

ATTENTION: Horizon service is limited to Product compliant in the country of use and ownership. If received, a non-compliant Product will not be serviced. Further, the sender will be responsible for arranging return shipment of the un-serviced Product, through a carrier of the sender's choice and at the sender's expense. Horizon will hold non-compliant Product for a period of 60 days from notification, after which it will be discarded.
