6. Align the battery tray with the tracks in the battery compartment and slide the tray all the way forward until the tray locks.

7. Connect the battery to the ESC (the ESC is now armed).

8. Keep the aircraft immobile and away from wind or the system will not initialize.
   • 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 like a continuous double beep after the flight battery is connected, recharge or replace the battery.

9. Reinstall the canopy hatch.

CAUTION: Always keep your hands away from the propeller. When armed, the motor will turn the propeller in response to any throttle movement.

Transmitter and Receiver Binding / Switching ON and OFF SAFE® Select

This product requires an approved Spektrum™ DSM2®/DSMX® compatible transmitter. Visit www.bindnfly.com for a complete list of approved transmitters.
The aircraft has an optional SAFE Select feature, which can be switched ON or OFF easily by binding in a specific manner as described below.
IMPORTANT: Before binding a transmitter, read the Transmitter Setup section of this manual to ensure that your transmitter is properly programmed for this aircraft.

Bind Plug Installation

Switching ON SAFE Select Binding Sequence

Binding Procedure / Switching ON SAFE Select
IMPORTANT: The included AR631 receiver has been programmed for operation specifically for this aircraft. Refer to the receiver manual for correct setup if the receiver is replaced or is used in another aircraft.

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. Move the transmitter controls to neutral (flight controls: rudder, elevators, and ailerons) or too low positions (throttle, throttle trim).*
Install a bind plug in the receiver bind port.
Place the aircraft level on its wheels, then connect the flight battery to the ESC. The motor will produce a series of sounds. The orange bind LED on the receiver will begin to flash rapidly.

Remove the bind plug from the bind port.
Take three steps away from the aircraft /receiver and then put the transmitter in inbind mode. Refer to your transmitter’s manual for specific binding instructions.
IMPORTANT: Do not point the transmitter’s antenna directly at the receiver while binding.
IMPORTANT: Keep away from large metal objects while binding.
The receiver is bound to the transmitter when the orange bind light on the receiver stays orange. The ESC will produce a series of sounds. The tones indicate the ESC is armed, provided the throttle stick and throttle trim are low enough to trigger arming.
IMPORTANT: Once bound, the receiver will retain its bind settings for that transmitter until it has been intentionally changed, even when power is cycled ON and OFF. Repeat the binding process as necessary.
SAFE Select ON Indication
Every time the receiver is powered ON the surfaces will cycle back and forth twice with a slight pause at a neutral position to indicate that SAFE Select is switched ON.
The throttle will not arm if the transmitter’s throttle control is not put at the lowest position. If problems are encountered, follow the binding instructions and refer to the transmitter troubleshooting guide for other instructions. If needed, contact the appropriate Horizon Product Support office.

Switching OFF SAFE Select Binding Sequence

Binding Procedure / Switching OFF SAFE Select
IMPORTANT: The included AR631 receiver has been programmed for operation specifically for this aircraft. Refer to the receiver manual for correct setup if the receiver is replaced or is used in another aircraft.

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.
Move the transmitter controls to neutral (flight controls: rudder, elevators, and ailerons) or too low positions (throttle, throttle trim). *
Install a bind plug in the receiver bind port.
Place the aircraft level on its wheels, then connect the flight battery to the ESC. The motor will produce a series of sounds.
The orange bind LED on the receiver will begin to flash rapidly. DO NOT remove the bind plug at this time.

Take three steps away from the aircraft /receiver and then put the transmitter in bind mode. Refer to your transmitter’s manual for specific binding instructions.
IMPORTANT: Do not point the transmitter’s antenna directly at the receiver while binding.
IMPORTANT: Keep away from large metal objects while binding.
The receiver is bound to the transmitter when the orange bind light on the receiver stays orange. The ESC will produce a series of sounds. The tones indicate the ESC is armed, provided the throttle stick and throttle trim are low enough to trigger arming.
Remove the bind plug from the bind port.
IMPORTANT: Once bound, the receiver will retain its bind settings for that transmitter until it has been intentionally changed, even when power is cycled ON and OFF. Repeat the binding process as necessary.
SAFE Select OFF Indication
Every time the receiver is powered ON the surfaces will cycle back and forth once to indicate that SAFE Select has been switched OFF.
The throttle will not arm if the transmitter’s throttle control is not put at the lowest position. If problems are encountered, follow the binding instructions and refer to the transmitter troubleshooting guide for other instructions. If needed, contact the appropriate Horizon Product Support office.

*Failsafe
If the receiver loses transmitter communication, the failsafe will activate. When activated, failsafe move the throttle channel to its preset failsafe position (low throttle) that was set during binding. All other channels move to actively level the aircraft in flight.

SAFE® Select Switch Designation

SAFE® Select technology can be easily assigned to any open switch (two or three positions) on the transmitter. With this new feature, you now have the flexibility to enable or disable the technology while in flight.
IMPORTANT: Before assigning your desired switch, ensure that the travel for that channel is set at 100% in both directions.

Assigning a switch
Bind the aircraft correctly to activate SAFE Select. This will allow the system to be assigned to a switch.
Hold both transmitters sticks to the inside bottom corners and toggle the desired switch five times (one toggle = full up and down) to assign that switch. The control surfaces of the aircraft will move, indicating the switch has been selected.
Repeat the process to deselect the switch or to assign a different switch if desired.
TIP: SAFE Select is assignable on any unused Channels 5–9.

AS3X Control Direction Test

This test ensures that the AS3X® control system is functioning properly.
Assemble the aircraft and bind your transmitter to the receiver before performing this test.

1. Raise the throttle just above 25%, then lower the throttle to activate AS3X.
   CAUTION: Keep all body parts, hair, and loose clothing away from a moving propeller, as these items could become entangled.
   IMPORTANT: The AR631 programming for this aircraft increases control surface movement when flaps are fully down.

2. Move the entire aircraft as shown and ensure the control surfaces move in the direction indicated in the graphic. If the control surfaces do not respond
   as shown, do not fly the aircraft. Refer to the receiver manual for more information.
   Once the AS3X system is active, control surfaces may move rapidly. This is normal. AS3X remains active until the battery is disconnected.

Center of Gravity (CG)

The CG location is measured from the leading edge of the wing at the root.
This CG location has been determined with the recommended Li-Po battery (EFLB22003S30) installed to the front edge of the battery tray.
Tip: Measure the CG with the aircraft inverted.
NOTICE: Install the battery but do not arm the ESC while checking the CG.
Personal injury may result.

In-Flight Trimming

During your first flight, trim the aircraft for level flight at 3/4 throttle with flaps and gear up. Make small trim adjustments with your transmitter’s trim switches to straighten the aircraft’s flight path.
After adjusting the trim do not touch the control sticks for 3 seconds. This allows the receiver to learn the correct settings to optimize AS3X performance.
Failure to do so could affect flight performance.

Flying Tips and Repairs

Consult local laws and ordinances before choosing a flying location.
Range Check your Radio System
Before you fly, range checks the radio system. Refer to your specific transmitter instruction manual for range test information.
Oscillation
Once the AS3X system is active (after advancing the throttle for the first time), you will normally see the control surfaces react to aircraft movement. In some flight conditions, you may see oscillation (the aircraft rocks back and forth on one axis due to overcontrol). If oscillation occurs, refer to the Troubleshooting Guide for more information.
Takeoff
Place the aircraft facing into the wind. Set your transmitter at a low rate and use your flaps switch to drop the flaps to takeoff or “half position”. Gradually increase the throttle to ¾ and steer with the rudder. Flaps make takeoffs shorter. As the tail comes off the ground, pull back gently on the elevator. When airborne, flip your gear switch to raise your landing gear. Climb to a comfortable altitude and then flip your flaps switch to level the flaps.
Flying
For your first flights with the recommended battery pack (EFLB22003S30), set your transmitter timer or a stopwatch to 5 minutes. After five minutes, land the aircraft. Adjust your timer for longer or shorter flights once you have flown 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.
Landing
Land the aircraft into the wind. Use high rate Elevator for landings. Use a small amount of throttle for the entire descent. Lower the throttle to ¼ and flip your flaps switch to deploy the flaps to the landing or “full down position”. Flaps will make the landing approach steeper and slower, and allow for a smoother landing. Flip your gear switch to lower your landing gear. This will slow the aircraft further.
Keep the throttle on until the aircraft is ready to flare. During a flare, keep the wings level and the aircraft pointed into the wind. Gently lower the throttle while pulling back on the elevator to bring the aircraft down on its wheels.
If landing on grass, it is best to hold full-up elevator after touchdown and when taxiing to prevent nosing over.
Once on the ground, avoid sharp turns until the plane has slowed enough to prevent scraping the wingtips.
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 finished flying, never leave the aircraft in direct sunlight or in a hot, enclosed area such as a car. Doing so can damage the aircraft.

WARNING: Always decrease throttle at propeller strike.

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 flight battery from over-discharge using Low Voltage Cutoff (LVC). Before the battery charge decreases too much, LVC removes the power supplied to the motor. Power to the motor pulses, showing that some battery power is reserved for flight 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 flying to LVC will damage the battery.
Tip: Monitor your aircraft battery’s voltage before and after flying by using a Li-Po Cell Voltage Checker (SPMXBC100, 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). 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 the paint. DO NOT handle the aircraft until the accelerant fully dries.

1. Disconnect the flight battery from the ESC (Required for Safety and battery life).
2. Power of the transmitter.
3. Remove the flight battery from the aircraft.
4. Recharge the flight battery.
5. Repair or replace all damaged parts.
6. Store the flight battery apart from the aircraft and monitor the battery charge.
7. Make note of the flight conditions and flight plan results, planning for future flights.

Motor Service
CAUTION: Always disconnect the flight battery before performing motor service.

What is Not Covered – This warranty is not transferable and does not cover (i) cosmetic damage, (ii) damage due to acts of God, accident, misuse, abuse, negligence, commercial use, or due to improper use, installation, operation or maintenance, (iii) modification of or to any part of the Product, (iv) attempted service by anyone other than a Horizon Hobby authorized service center, (v) Product not purchased from an authorized Horizon dealer, or (vi) Product not compliant with applicable technical regulations, or (vii) use that violates any applicable laws, rules, or regulations.
OTHER THAN THE EXPRESS WARRANTY ABOVE, HORIZON MAKES NO OTHER WARRANTY OR REPRESENTATION AND HEREBY DISCLAIMS ANY  AND ALL IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF NON-INFRINGEMENT, MERCHANTABILITY, AND FITNESS FOR A PARTICULAR PURPOSE. THE PURCHASER ACKNOWLEDGES THAT THEY ALONE HAVE DETERMINED THAT THE PRODUCT WILL SUITABLY MEET THE REQUIREMENTS OF THE PURCHASER’ INTENDED USE.
Purchaser’s Remedy – Horizon’s sole obligation and purchaser’s sole and exclusive remedy shall be that Horizon will, at its option, either (i) service, or (ii) replace, any Product determined by Horizon to be defective. Horizon reserves the right to inspect any and all Product(s) involved in a warranty claim. Service or replacement decisions are at the sole discretion of Horizon. Proof of purchase is required for all warranty claims. SERVICE OR REPLACEMENT AS PROVIDED UNDER THIS WARRANTY IS THE
PURCHASER’S SOLE AND EXCLUSIVE REMEDY.
Limitation of Liability – HORIZON SHALL NOT BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, LOSS OF PROFITS OR PRODUCTION OR COMMERCIAL LOSS IN ANY WAY, REGARDLESS OF WHETHER SUCH CLAIM IS BASED IN CONTRACT, WARRANTY, TORT, NEGLIGENCE, STRICT LIABILITY OR ANY OTHER THEORY OF LIABILITY, EVEN IF HORIZON HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. Further, in no event, shall the liability of Horizon exceed the individual price of the Product on which liability is asserted. As Horizon has no control over use, setup, final assembly, modification or misuse, no liability shall be assumed nor accepted for any resulting damage or injury. By the act of use, setup, or assembly, the user accepts all resulting liability. If you as the purchaser or user are not prepared to accept the liability associated with the use of the Product, the purchaser is advised to return the Product immediately in new and unused condition to the place of purchase.
Law – These terms are governed by Illinois law (without regard to conflict of law principles). This warranty gives you specific legal rights, and you may also have other rights which vary from state to state. Horizon reserves the right to change or modify this warranty at any time without notice.

WARRANTY SERVICES
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.
Inspection or Services – If this Product needs to be inspected or serviced and is compliant in the country you live and use the Product in, please use the Horizon Online Service Request submission process found on our website or call Horizon to obtain a Return Merchandise Authorization (RMA) number. Pack the Product securely using a shipping carton. Please note that original boxes may be included, but are not designed to withstand the rigors of shipping without additional protection. Ship via a carrier that provides tracking and insurance for lost or damaged parcels, as Horizon is not responsible for merchandise until it arrives and is accepted at our facility. An Online Service Request is available at http://www.horizonhobby.com/content/_servicecenter_render- service-center. If you do not have internet access, please contact Horizon Product Support to obtain an RMA number along with instructions for submitting your product for service.

When calling
Horizon, you will be asked to provide your complete name, street address, email address, and phone number where you can be reached during business hours.
When sending products into Horizon, please include your RMA number, a list of the included items, and a brief summary of the problem.
A copy of your original sales receipt must be included for warranty consideration. Be sure your name, address, and RMA number are clearly written on the outside of the shipping carton.
NOTICE: Do not ship LiPo batteries to Horizon. If you have any issues with a LiPo battery, please contact the appropriate Horizon Product Support office. 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 ½ 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 the 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 Products for a period of 60 days from notification, after which it will be discarded.
