General Binding Tips and Failsafe

  • The included receiver has been specifically programmed for 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 / Switching ON and OFF SAFE Select

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 binding. This process defines the failsafe settings. You can use either the bind button on the receiver case OR a conventional bind plug to complete the binding and SAFE Select process.

Using The Bind Button…To Enable SAFE SelectSAFE SELECT ENABLED: The control surfaces cycle back and forth twice with a slight pause at neutral position every time the receiver is powered on.

Battery Installation and ESC Arming

Battery SelectionA 3S 2200mAh LiPo battery is required. The Spektrum 2200mAh 11.1V 3S 30C IC3 LiPo battery (SPMX22003S30) is recommended. 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 Spektrum Li-Po battery packs to fit in the fuselage. Be sure the model balances at the recommended CG before flying.

  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 (A) to remove.
  3. Install a fully charged battery B) and secure it into place using the hook an loop strap (C). See the Adjusting the Center of Gravity instructions for more information.
  4. Connect the battery to the ESC. If you have not completed the bind sequence, do so at this time as outlined in this manual.CAUTION: Always keep hands away from the propellers. When armed, the motor will turn the propellers in response to any throttle movement.
  5. Keep the aircraft immobile and away from wind or the system will not initialize.• The motor will emit a series of rising tones when the battery is connected, and then tones indicating the number of cells connected.• An LED will light on the receiver when it is initialized
  6. Reinstall the battery hatch.ESC TonesIf the ESC sounds a continuous double beep after the flight battery is connected, recharge or replace the battery.

Throttle travel reduced below 100%
Throttle reversed
Throttle trim raised
Continuous double tones Battery voltage is beyond acceptable range Verify battery is a 11.1V 3-cell LiPo
Verify battery is fully charged

Control Surface Centering

After assembly and transmitter setup, confirm that the control surfaces are centered. The model must be powered up and bound to the transmitter in AS3X mode, with the throttle left at zero. When enabled, SAFE mode is active at power up. AS3X mode is activated when the throttle is raised above 25% for the first time after being powered on. It is normal for the control surfaces to respond to aircraft movement if the aircraft is in AS3X or SAFE modes.

  1. Verify the trims and subtrims on your transmitter are zero
  2. Power up the model in AS3X mode and leave the throttle at zeroNOTICE: Be aware of the pushrod bottoming out in the clevis. Do not thread the pushrod too far into the clevis or the pushrod will damage the clevis.
  3. Center the rudder with the vertical stabilizer. If adjustment is required, turn the clevis on the linkage to change the length between the servo arm and the control horn until the rudder is straight.
  4. Center the elevator by aligning the elevator with the horizontal stabilizer. If adjustment is required, adjust the linkage length as in step 3 as necessary.
  • Turn the linkage clockwise or counterclockwise until the control surface is centered.
  • Attach the linkage to the servo arm or control horn after adjustment

Control Horn and Servo Arm Settings

The table to the right shows the factory settings for the control horns and servo arms. Fly the aircraft at factory settings before making changes.NOTICE: If control throws are changed from the factory settings, the AR631 gain values may need to be adjusted. Refer to the Spektrum AR631 manual for adjustment of gain values.After flying, you may choose to adjust the linkage positions for the desired control response. See the table to the right.

SAFE® Select Switch Designation

SAFE ® Select technology can be assigned to any open switch (2 or 3 position) controlling a channel (5–9) on your transmitter. Once assigned to a switch, SAFE select ON gives you the flexibility to choose SAFE technology or AS3X mode while in flight. If the aircraft is bound with SAFE select OFF, the aircraft will be in AS3X mode exclusively.

IMPORTANT: Before assigning your desired switch, ensure that the travel for that channel is set at 100% in both directions and the aileron, elevator, rudder and throttle are all on high rate with the travel at 100%.

CAUTION: Keep all body parts well clear of the rotor and keep the aircraft securely restrained in case of accidental throttle activation.TIP: SAFE Select is assignable on any unused channels 5–9. See your transmitter manual for more information about assigning a switch to a channel.TIP: Use your radio channel monitor to confirm that the four primary channels are showing 100% travel while assigning the switch.TIP: Use the channel monitor to make sure the switch you are assigning for SAFE Select is active and driving a channel between 5-9 and that it is traveling 100% in each direction.TIP: Make sure your four primary channels are not reversed if you are having trouble assigning a SAFE Select switch.

Assigning a switch

  1. Bind the aircraft to choose SAFE Select ON. This will allow the system to be assigned to a switch.
  2. Hold both transmitters sticks to the inside bottom corners and toggle the desired switch 5 times (1 toggle = full up and down) to assign that witch. 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 if desired.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 Aux3, and +/- 100% travel on the switch.

Smart Technology Telemetry

This aircraft includes Spektrum Smart Technology in the ESC and receiver, which can provide telemetry information such as battery voltage and ESC temperature.To take advantage of Smart Technology, you will need a compatible transmitter. A firmware update for your transmitter may be required.To access all the available features of Smart Technology, use Spektrum Smart batteries to power this aircraft. In addition to ESC data, Spektrum Smart batteries can communicate detailed battery data through the Smart Technology system.

To View Smart Telemetry:

  1. Begin with the transmitter bound to the receiver
  2. Power on the transmitter.
  3. Power on the aircraft.
  4. The Smart Logo appears under the battery logo on the home page. A signal bar appears in the top left corner of the screen.*
  5. Scroll past the servo monitor to view Smart technology screens.* If the transmitter that you intend to use with this aircraft is not displaying telemetry data, visit spektrumrc.com and update your firmware. With the latest firmware installed on your transmitter the telemetry option should now be functional on your transmitter. For more information about compatible transmitters, firmware updates, and how to usethe Smart Technology on your transmitter, visit spektrumrc.com.

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.Elevators

  1. Pull the elevator stick back. The stabilators should move up, which will cause the aircraft to pitch up.
  2. Push the elevator stick forward. The stabilators should move down, which will cause the aircraft to pitch down.

Rudder

  1. Move the rudder stick to the left. The rudder and the nose wheel should move to the left, which will cause the aircraft to yaw left.
  2. Move the rudder stick to the right. The rudder and the nose wheel should move to the right, which will cause the aircraft to yaw right.

AS3X Control Response 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 to any setting above 25%, then lower the throttle to activate AS3X technology. CAUTION: Keep all body parts, hair and loose clothing away from the Propeller, as these items could become entangled.
  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

WARNING: Install the battery but do not connect it to the ESC while checking the CG. Personal injury may result.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 (SPMX22003S30) installed all the way forward in the battery compartment.

Dual Rates

To obtain the best flight 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 flight.

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

In Flight Trimming (BNF Basic)

During your first flight, trim the aircraft for level flight. 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 SystemBefore you fly, range check the radio system. Refer to your specific transmitter instruction manual for range test information.

Hand LaunchSet your dual rate switches to low rate. Hold the aircraft fuselage under the wing and gradually increase the throttle to ¾. Launch the aircraft into the wind with the wings level. Allow the aircraft to climb to a comfortable altitude.

FlyingAlways choose a wide-open space for flying your aircraft. It is recommended that you fly at a designated RC flying field. Always avoid flying near houses, trees, wires and buildings. Avoid flying in areas where there are many people, such as parks, schoolyards, or soccer fields.

OscillationOnce 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.

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.

LandingFor your first flights with the recommended battery pack ( SPMX22003S30), set your transmitter timer or a stopwatch to 8 minutes. After 8 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.

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.

WARNING: Always decrease throttle at propeller strike.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.

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 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).

RepairsThanks to the EPO 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 paint. DO NOT handle the aircraft until accelerant fully dries.

SAFE Select Flying Tips

When flying in SAFE Select mode the aircraft will return to level flight any time the aileron and elevator controls are at neutral. Applying aileron or elevator control will cause the airplane to bank, climb or dive, and the amount the stick is moved will determine the attitude the airplane flies. Holding full control will push the aircraft to the pre-determined bank and roll limits but it will not go past those angles. When flying with SAFE Select it is normal to hold the control stick deflected with moderate aileron input when flying through a turn. To fly smoothly with SAFE Select avoid making frequent control changes and don’t attempt to correct for minor deviations. With SAFE Select, holding deliberate control inputs will command theaircraft to fly at a specific angle and the model will make all corrections to maintain that flight attitude.

Return the elevator and aileron controls to neutral before switching from SAFE Select mode to AS3X mode. If you do not neutralize controls when switching into AS3X mode, the control inputs used for SAFE Select mode will be excessive for AS3X mode and the aircraft will react immediately.

Differences between SAFE Select and AS3X modesThis section is generally accurate but does not take into account flight speed, battery charge status, and many other limiting factors.

  • In SAFE Select mode the aircraft will self level when the control stick is neutralized.In AS3X mode the aircraft will continue to fly at its present attitude when the control stick is neutralized.
  • In SAFE Select mode holding a small amount of control will result in the model banking or pitching to a moderate angle and remaining at that angle as long as the control stick doesn’t move.In AS3X mode holding a small amount of control will result in the model continuing to pitch or roll at a slow rate as long as the control stick doesn’t move.
  • In SAFE Select mode holding full control will result in the airplane banking or pitching to the predetermined limits and the aircraft will keep flying at that attitude as long as the control stick is fully deflected.In AS3X mode holding full control will result in the aircraft pitching or rolling as fast as possible, and it will continue to rapidly change attitude as long as the control stick is fully deflected.

Post Flight

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

AMA National Model Aircraft Safety Code

Academy of Model AeronauticsNational Model Aircraft Safety Code

Effective January 1, 2018A 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 aircraft using 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.
