Smart Technology and Flight Times

When using the recommended 4S 2200mAh battery, the expected flight time is 3–5 minutes. Actual flight times may vary, based on the condition and performance of the particular battery, flying conditions, and throttle management. Flight times will typically be longer when using a lower power setting. Set your flight timer according to your flying style. When using a compatible Spektrum AirWare equipped transmitter and Smart-technology receiver along with the installed Smart-technology ESC, real-time battery voltage telemetry is available to minimize or eliminate the need for a timer. See the Integrated ESC Telemetry section of this manual for more information.

Receiver Selection and Installation PNP

The recommended receiver for this aircraft is the Spektrum AR631.
If you choose to install a different receiver, it needs to be a 4-channel or more full range (sport) receiver. Refer to the manual of your chosen receiver for correct installation and operation instructions.
AR631 Installation

1. Lift the rear of the canopy to remove the canopy from the top of the fuselage.
2. Attach the appropriate control surfaces to their respective ports on the receiver using the table at the right.
3. Using double-sided servo tape, mount the receiver to the flat area, as shown. The receiver should be mounted in the orientation shown, parallel to the length of the fuselage, with the label facing up and the servo ports facing the front of the aircraft. The orientation of the receiver is critical for all AS3X® and SAFE® technology setups.

CAUTION: Incorrect installation of the receiver could cause a crash.

ANTENNA INSTALLATION
The AR631 receiver has a coaxial style antenna. We recommend installing the antenna as far as possible from metal, batteries, or carbon fiber to maximize signal reception performance.NOTICE: Do not cut, kink, or modify the antenna. Damage to the coaxial portion of an antenna will reduce the performance of the antenna. Shortening or cutting off the 31mm tip will reduce the range.

Assemble the Aircraft

Horizontal Tail Installation

1. Slide the horizontal tail (A) into the slot in the rear of the fuselage. Ensure the control horn faces down.
2. With a 2mm Allen driver, secure the horizontal tail piece in place using the included M3 x 26 countersunk machine screw (B). Use caution to avoid over-tightening the screw.
3. Attach the clevis to the elevator control horn (see instructions for clevis connection).

Clevis Installation

1. Slide the retaining tube off the clevis body.
2. Carefully spread the clevis.
3. Insert clevis pin into control horn.
4. Slide the retaining tube into position on the clevis body.

Wing Installation

1. Remove the canopy hatch.
2. Guide the flap, retract and aileron servo connectors (A) through the hole (B) located in the bottom of the fuselage as shown.
3. Plug in the Y-harnesses into the receiver. The single connector side of the Y- harnesses are marked Ail, Gear, and Flap.
4. Align the wing with the fuselage, and use a 2mm Allen driver to secure it into position with the included 4 M3 x 26 countersunk machine screws (C).
5. Reinstall the canopy hatch on the fuselage. Disassemble in reverse order.

CAUTION: DO NOT crush or otherwise damage the wiring when attaching the wing to the fuselage.

Propeller Installation

IMPORTANT: Install the propeller after all system setups are complete to reduce the chance of accidental injury.

1. Install back side of propeller hub (A), propeller (B), and front side propeller hub (C) onto the motor shaft (D). The propeller size numbers (10.5 x 8) must face forward for correct propeller operation.
2. Install the spinner nut (E) to secure the propeller into place. Use a small screw driver or hex wrench inserted into the small hole (Inset) and turn clockwise to secure it into place.

Optional Drop Tank Installation

Slide the optional drop tanks (A) into the rails (B) on each wing. Check the Center of Gravity with the drop tanks installed. See Adjusting the Center of Gravity for more information.

Center of Gravity (CG)

After installing the battery (in the recommended position) and before power- ing on the ESC, verify the CG. The CG location starting point is 73mm (range: 73mm±3mm) behind the leading edge, as shown. 3S 2200mAh Smart battery CG position – The battery is installed all the way forward in battery compartment. Only the front battery strap will be used. 4S 3200mAh Smart battery CG position – The battery is installed centered in the battery tray, using both front and rear battery straps. Balance the aircraft inverted on your fingertips adjacent to the fuselage under the wings.

• If the nose goes down, move the flight battery back until the aircraft balances.
• If the nose goes up, move the flight battery forward until the aircraft balances.

**Control Surface Direction

**

Switch on the transmitter and connect the battery. Use the transmitter to operate the aileron, elevator, and rudder controls. View the aircraft from the rear when checking the control directions.

NOTICE: Bind the aircraft and transmitter before performing these tests. Move the transmitter controls to make sure the aircraft control surfaces move correctly and in the proper direction. Make sure the tail linkages move freely.

Elevators

1. Pull the elevator stick back. The elevator should move up, which will cause the aircraft to pitch up.

2. Push the elevator stick forward. The elevator should move down, which will cause the aircraft to pitch down.
   Ailerons

3. Move the aileron stick to the left. The left aileron should move up and the right aileron should move down, which will cause the aircraft to bank left.

4. Move the aileron stick to the right. The right aileron should move up and the left aileron down, which will cause the aircraft to bank right.
   Rudder

5. Move the rudder stick to the left. The rudder should move to the left, which will cause the aircraft to yaw left.

6. Move the rudder stick to the right. The rudder should move to the right, which will cause the aircraft to yaw right.

Control Centering

After assembly and transmitter setup, confirm that the control surfaces are centered. If the control surfaces are not centered, mechanically center the control surfaces by adjusting the linkages. If adjustment is required, turn the clevis on the linkage to change the length of the linkage between the servo arm and the control horn. After binding a transmitter to the aircraft receiver, set the trims and sub- trims to 0, then adjust the clevises to center the control surfaces.

**Flight Battery Installation and Electronic Speed Control (ESC)

Arming **

Battery Selection
We recommend the Spektrum™ 2200mAh 14.8V 4S 30C Li-Po battery (SP-MX22004S30). Refer to the Optional Parts List for other recommended batter-ies. If using a battery other than those listed, the battery should be within the range of capacity, dimensions and weight of the Spektrum 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 back of the canopy hatch (A) to remove.
3. For added security, apply the loop side (soft side) of the optional hook and loop tape (B) to the bottom of your battery, and the hook side to the battery tray.
4. Install the fully charged battery (C) all the way to the front of the battery compartmant as shown. Secure using the hook and loop straps (D).
5. Connect the battery to the ESC (the ESC is now armed).
6. Keep the aircraft immobile and away from wind or the system will not initialize.
   • The ESC will sound a series of tones (refer to 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.
7. Reinstall the canopy hatch.

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

General Binding Tips and Failsafe BNF

• The included receiver has been specifically programmed for the operation of this aircraft. Refer to the receiver manual for correct setup if the receiver is replaced.
• Keep away from large metal objects while binding.
• Do not point the transmitter’s antenna directly at the receiver while binding.
• The orange LED on the receiver will flash rapidly when the receiver enters bind mode.
• Once bound, the receiver will retain its bind settings for that transmitter until you re-bind.
• If the receiver loses transmitter communication, the failsafe will activate. Failsafe moves the throttle channel to low throttle. Pitch and roll channels move to actively stabilize the aircraft in a descending turn.
• If problems occur, refer to the troubleshooting guide or if needed, contact the appropriate Horizon Product Support office.

Transmitter and Receiver Binding / Enabling and Disabling SAFE Select BNF

The BNF Basic version of this airplane includes SAFE Select technology, enabling you to choose the level of flight protection. SAFE mode includes angle limits and automatic self leveling. AS3X mode provides the pilot with a direct response to the control sticks. SAFE Select is enabled or disabled during the bind process. With SAFE Select disabled the aircraft is always in AS3X mode. With SAFE Select enabled the aircraft will be in SAFE Select mode all the time, or you can assign a switch to toggle between SAFE Select and AS3X modes. Thanks to SAFE Select technology, this aircraft can be configured for full-time SAFE mode, full-time AS3X mode, or mode selection can be assigned to a switch.
IMPORTANT: Before binding, read the transmitter setup section in this manual and complete the transmitter setup table to ensure your transmitter is properly programmed for this aircraft.
IMPORTANT: Move the transmitter flight controls (rudder, elevators, and ailerons) and the throttle trim to neutral. Move the throttle to low before and during bind-ing. This process defines the failsafe settings. You can use either the bind button on the receiver case or the conventional bind plug to complete the binding and SAFE Select process. SAFE Select can also be activated via Forward Programming in compatible transmitters.

Using The Bind Button…

To Enable SAFE Select

SAFE SELECT ENABLED: The control surfaces cycle back and forth twice with a slight pause at neutral every time the receiver is powered on.

To Disable SAFE Select

SAFE SELECT DISABLED: The control surfaces cycle back and forth once every time the receiver is powered on.

Using The Bind Plug…

To Enable SAFE Select

SAFE SELECT ENABLED: The control surfaces cycle back and forth twice with a slight pause at neutral every time the receiver is powered on.

To Disable SAFE Select

SAFE SELECT DISABLED: The control surfaces cycle back and forth once every time the receiver is powered on.

SAFE® Select Switch Designation BNF

Once SAFE Select is enabled, you can choose to fly in SAFE mode full-time, or assign a switch. Any switch on any channel between 5 and 9 can be used on your transmitter.
If the aircraft is bound with SAFE Select disabled, the aircraft will be in AS3X mode exclusively.

CAUTION: Keep all body parts well clear of the propeller and keep the aircraft securely restrained in case of accidental throttle activation.

IMPORTANT: To be able to assign a switch, first verify:

• The aircraft was bound with SAFE Select enabled.
• Your choice for the SAFE Select switch is assigned to a channel between 5 and 9 (Gear, Aux1-4), and travel is set at 100% in each direction.
• The aileron, elevator, rudder and throttle direction are set to normal, not reverse.
• The aileron, elevator, rudder and throttle are set to 100% travel. If dual rates are in use, the switches need to be in the 100% position.

See your transmitter manual for more information about assigning a switch to a channel.

Assigning a Switch

1. Power on the transmitter.
2. Power on the aircraft.
3. Hold both transmitter sticks to the inside bottom corners, and toggle the desired switch 5 times quickly (1 toggle = full up and down).
4. The control surfaces of the aircraft will move, indicating the switch has been selected.

Repeat the process to assign a different switch or to deactivate the current switch.

TIP: Use the channel monitor to verify channel movement.

• This example of the channel monitor shows the stick positions for assigning a switch, the switch selection on Aux2, and +/- 100%travel on the switch.

Forward Programming
Assign the SAFE Select channel through forward programming on your compatible Spektrum transmitter.

Forward Programming SAFE Select Setup

DX series, NX series, iX series

| 1. Begin with the transmitter bound to the receiver.

In Flight Trimming BNF

During your first flight, trim the aircraft for your flying style in AS3X flight mode. Flight trim is usually performed between 70–100% power setting, per your preference. 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 check 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 past 25% for the first time), the control surfaces react to aircraft movement. In some flight conditions you may see oscillation about an axis. If oscillation occurs, refer to the Troubleshooting Guide for more information.
Takeoff
Place the aircraft facing into the wind. Set the transmitter in low rate, and use the flaps switch to drop the flaps to the half, or partial flap 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 the aircraft is airborne, flip the gear switch to raise the landing gear. Climb to a comfortable altitude, and then flip the flaps switch to raise the flaps.
Flying
For your first flight with the recommended battery pack (SPMX22004S30). Set the transmitter timer or monitor the flight battery voltage telemetry as described in the Smart Technology and Flight Times section. If at any time the motor pulses, land the aircraft immediately to recharge the flight battery. See the Low Voltage Cutoff (LVC) section for 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 the flaps switch to deploy the flaps to the appropriate position, usually full down. Flaps will make the landing approach steeper and slower, and allow for a smoother landing. Flip the gear switch to lower the landing gear. This will slow the aircraft further. Keep the throttle on until the aircraft is ready to flare. During 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. When landing on grass, 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. Failure to do so could result in extra damage to the airframe, as well as damage to the ESC and motor.

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 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 the 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.

Tip: Monitor your aircraft battery’s voltage before and after flying by using a Li-Po Battery Voltage Checker (SPMXBC100, sold separately).
Repairs
Thanks to the EPO 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.

AMA National Model Aircraft Safety Code

Effective January 1, 2018
A model aircraft is a non-human-carrying device capable of sustained flight within visual line of sight of the pilot or spotter(s). It may not exceed limitations of this code and is intended exclusively for sport, recreation, education and/or competition. All model flights must be conducted in accordance with this safety code and related AMA guidelines, any additional rules specific to the flying site, as well as all applicable laws and regulations.
As an AMA member I agree:

• I will not fly a model aircraft in a careless or reckless manner.
• I will not interfere with and will yield the right of way to all human-carrying aircraftusing AMA’s See and Avoid Guidance and a spotter when appropriate.
• I will not operate any model aircraft while I am under the influence of alcohol or any drug that could adversely affect my ability to safely control the model.
• I will avoid flying directly over unprotected people, moving vehicles, and occupied structures.
• I will fly Free Flight (FF) and Control Line (CL) models in compliance with AMA’s safety programming.
• I will maintain visual contact of an RC model aircraft without enhancement other than corrective lenses prescribed to me. When using an advanced flight system, such as an autopilot, or flying First-Person View (FPV), I will comply with AMA’s Advanced Flight System programming.
• I will only fly models weighing more than 55 pounds, including fuel, if certified through AMA’s Large Model Airplane Program.
• I will only fly a turbine-powered model aircraft in compliance with AMA’s Gas Turbine Program.
• I will not fly a powered model outdoors closer than 25 feet to any individual, except for myself or my helper(s) located at the flightline, unless I am taking off and landing, or as otherwise provided in AMA’s Competition Regulation.
• I will use an established safety line to separate all model aircraft operations from spectators and bystanders.
