motor will turn the propeller in response to any throttle movement. Binding

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 / Enabling 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.

• 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 trims to neutral. Move the throttle to low before and
  during binding.

• You can use either the bind button on the receiver or the conventional bind plug to complete the binding process.

• A bind plug extension has been provided in BNF Basic version models. It will be labeled and located in the battery or radio compartment for easy access.

SAFE Select can also be activated via Forward Programming in compatible transmitters.

SAFE® Select Switch Designation BNF
Stick Inputs

• 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.
• TIP: If a SAFE Select switch is desired for your 6-function aircraft, and you are using a 6 channel transmitter, the SAFE Select switch channel will have to be shared with either channel 5 or 6 of the transmitter.

Forward Programming

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

• For more information about setting SAFE Select and using Forward Programming, please refer to the following link for a detailed video:
• https://www.youtube.com/watch?v=o-46P066cik

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.
SAFE Select Switch Assignment Stick Positions

• 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 SAFE Select Setup

DX series, NX series, iX series| 1. Begin with the transmitter bound to the receiver.
2. Power ON the transmitter.
3. Assign a switch for SAFE Select that is not already in use for another function. Use any open channel between 5 and 9 (Gear, Aux1-4).

Control Direction Test

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.
The BNF Basic version of this model has a built in aileron to rudder mix, when the ailerons are deflected the rudder will move.
Elevator

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

Ailerons

1. 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.
2. Move the aileron stick to the left. The left aileron should move up and the right aileron down, which will cause the aircraft to bank left.

Rudders

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

Flaps

1. Move your flap control switch to the partial flaps position.
2. Confirm that the flaps move down.
3. Move flap control switch to the full flaps position.
4. Confirm the flaps move farther down than in step two.

AS3X 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 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.
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.
   • Due to different effects of torque, lift, and drag some aircraft require trim changes with different speeds and throttle settings. Mixes are preloaded into the receiver to compensate for these changes. The mixes become active the first time the throttle is raised above 25%. The control surfaces may be offset slightly at different throttle settings after the first time throttle is raised.
   • Trimming the plane in flight should be done at 80-100% throttle for best results.

Control Surface Centering and Adjusting a Clevis

• IMPORTANT: Perform the Control Direction Test before performing control surface centering.
• While SAFE is inactive, mechanically center the control surfaces.
• IMPORTANT: Correct operation of the SAFE system requires sub-trim and trim at 0.
  After binding a transmitter to the receiver, set the trims and sub-trims to 0, ensure the servo arms are in the correct positions, then adjust the linkages to center the control surfaces.

Control Horn and Servo Arm Factory 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.
• After flying, you may choose to adjust the linkage positions for the desired control response. See the table to the right.

Dual Rates and Control Throws

• Program your transmitter to set the rates and control throws to the values given. These values have been tested and are a good starting point to achieve successful flight.
• After flying, you may choose to adjust the values for the desired control response.

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 (SPMX22004S30) installed to the front edge of the battery tray. Check the CG with the model inverted, with the landing gear retracted. Adjust the battery forward or aft as needed to achieve the proper CG location.
• CAUTION: Install the battery but do not arm the ESC while checking the CG. Personal injury may result.

SAFE Select Flying Tips BNF

• 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. 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. Holding deliberate control inputs will command the aircraft to fly at a specific angle, and the model will make all corrections to maintain that flight attitude.
• When flying with SAFE Select, throttle will make the aircraft climb or descend. Full throttle will cause the aircraft to pitch up and climb slightly. Mid throttle will keep the airplane flying level. Low throttle will cause the airplane to descend slightly nose-down.
• 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 modes
  This section is generally accurate but does not take into account flight speed, battery charge status, and other limiting factors.

slowly
Holding full control| Aircraft will bank or pitch to the predetermined limits and maintain the attitude| Aircraft will continue to roll or pitch rapidly
Throttle| Full throttle: Climb Neutral: Level flight Low throttle: Descend| Throttle will not affect flight response.

In-Flight Trimming

• During your first flight, trim the aircraft for level flight at 80-100% throttle. Make small trim adjustments with your transmitter’s trim switches to achieve straight and level flight.
• After adjusting 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.
