General Binding Tips and Failsafe BNF

• 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.

Low Voltage Cutoff (LVC)

• When a Li-Po battery is discharged below 3V per cell, it will not hold a charge. The aircraft’s ESC protects the flight battery from over-discharge using Low Voltage Cutoff (LVC).
• Once the battery discharges to 3V per cell, the LVC will reduce the power to the motor in order to leave adequate power to the receiver and servos to land the airplane.
• When the motor power decreases, land the aircraft immediately and replace or recharge the flight battery.
• Always disconnect and remove the Li-Po battery from the aircraft after each flight. Charge your Li-Po battery to about half capacity before storage. Make sure the battery charge does not fall below 3V per cell. Failure to unplug a connected battery will result in trickle discharge.
• For your first flights, set your transmitter timer or a stopwatch to 4 minutes. Adjust your timer for longer or shorter flights once you have flown the model.
  NOTICE: Repeated flying to LVC will damage the battery.

Install the Transmitter Batteries

1. Remove the battery cover.
2. Install the included four AA batteries, noting proper polarity.
3. Reinstall the battery cover.

Low Battery Alarm
When the transmitter battery voltage drops below 4.7 volts, an alarm sounds and the voltage LEDs flash. Replace the batteries immediately. If the alarm sounds while flying, land your aircraft as soon as possible.
CAUTION: Do not attempt to recharge the included AA batteries. These batteries are not rechargeable. Charging non-rechargeable batteries may cause the batteries to burst, resulting in injury to persons and/or damage to property.

Transmitter Switches and LEDs

• Bind/Panic Button : This button is used to control the Bind and Panic Recovery Mode functions.
  • See the Binding section for information on re-binding your transmitter and aircraft if necessary. The included transmitter comes bound to the receiver/aircraft from the factory, therefore binding is not typically necessary.
  • See the Sensor Assisted Flight Envelope (SAFE) Technology section for information about Panic Recovery mode.
• Hi/Lo Rate Switch: This switch supports high and low rate functions on the elevator and aileron channels.
  • We recommend using low rates when first learning to fly or for smooth and more precise maneuvering, and high rates for more aggressive maneuvers and aerobatics.
  • In the upper, or “HI” position, servo travel is 100% on these channels.
  • In the lower, or “LO,” position, servo travel decreases to 70%. Flight Mode Switch: This switch is used to select the SAFE flight mode. See the Sensor Assisted Flight Envelope (SAFE) Technology section for information  about the various SAFE flight modes.
• Throttle Cut Switch: This switch activates throttle cut. With the throttle cut on (switch position 1), throttle input from the throttle stick is deactivated. This safety feature ensures any accidental bump of the throttle stick will not activate the motor while the flight battery is connected. With the throttle cut off (switch position 0), any position of the throttle stick above the lowest setting will activate the aircraft motor.
  NOTICE: Always ensure the throttle stick is at the lowest setting before switching the throttle cut function off. Failure to do so will result in the motor activating.

LED and Audible Indications

• Flashing with beeps: The transmitter is in bind mode, because the bind button was held down while the transmitter was powered on. See the Binding section for more information.
• Pulsates with one low tone beep every 2 seconds: The transmitter battery voltage has dropped below 4.7 volts. Replace the transmitter batteries immediately. If this happens while flying, land the aircraft as soon as possible.
• Inactivity Alarm: If the transmitter is left inactive for 10 minutes, it will begin to beep until the sticks are moved or the power is turned off.

Power ON / OFF the Transmitter

Slide the power button to power the transmitter ON. The LED indicator will illuminate green when the transmitter is ON and transmitting. To power the transmitter OFF, slide the power button to the OFF position.

Transmitter Setup, BNF

IMPORTANT: This aircraft is compatible with Spektrum transmitters. Binding to an SLT transmitter other than the Spektrum SLT6LP will not provide full functionality.

Bind the Transmitter and Receiver

• Binding is the process of programming the aircraft re-ceiver with the identification code of the transmitter so the receiver will only connect to that specific transmitter.
  The included transmitter was bound to the aircraft at the factory. If the aircraft does not respond to transmitter control inputs when the batteries in the aircraft and transmitter are fully charged, the aircraft receiver and transmitter may need to be re-bound.
  To re-bind the transmitter and receiver:

  1. Power OFF the transmitter.

  2. Set the throttle stick to the low position and all other controls to neutral.* Ensure the aircraft is immobile.
     IMPORTANT: The throttle will only arm if the transmitter throttle control is at the lowest position.

  3. Connect the flight battery to the ESC. The receiver will cycle between DSMX and SLT approximately every 20 seconds. The receiver LED is visible with the wing removed.
     Transmitter| LED Pattern
     ---|---
     DSMX| rapid constant flashes
     SLT| 3 rapid flashes, 1 pause (repeat)

  4. Press and hold the bind button (button A) on the transmitter while powering ON the transmitter. The receiver LED will glow solid when the receiver and transmitter are bound. The aircraft will initialize and the controls will function normally.

• Once properly bound, the receiver and transmitter will retain their bind for future flights.

• If you encounter problems, refer to the troubleshooting guide. If necessary, contact the appropriate Horizon Hobby product support office.

* Failsafe
The receiver stores the position of the transmitter throttle control at the time of binding as the failsafe position. If the receiver should ever lose communication with the transmitter, the failsafe function will activate. Failsafe moves the throttle channel to its preset failsafe position (low throttle) that was stored during binding. All other control channels move to put the aircraft in a slowly descending circle until radio link is re- established.

Charge the Aircraft Battery

NOTICE: Inspect the battery to make sure it is not dam-aged e.g., swollen, bent, broken or punctured. Charge only batteries that are cool to the touch and are not damaged.
Always charge the aircraft battery before flying.

1. Insert the charger into a USB port.

2. Connect the battery to the charger.
   CHARGING (Solid Orange LED)
   MAX CHARGE (Solid Green LED)
   Disconnect the flight battery from the charger immediately upon completion of charging.

   • CAUTION: Only use chargers specifically designed to charge the included Li-Po battery. Failure to do so could result in fire, causing injury or property damage.
   • CAUTION: Never exceed the recommended charge rate.
   • CAUTION: Once charging is complete, immediately remove the battery.Never leave a battery connected to the charger.

Install the Aircraft Battery

• Keep the aircraft and transmitter away from large metal objects, wireless sources or other transmitters while installing the battery.
• Each time the aircraft initializes from a power cycle, it will default to SAFE mode.
  CAUTION: Always disconnect the Li-Po flight battery from the aircraft receiver when not flying to avoid over-discharging the battery. Batteries discharged to a voltage lower than the lowest approved voltage may become damaged, resulting in loss of performance and potential fire when batteries are charged.

Control Direction Test

WARNING: Do not perform this or any other equipment test without turning on throttle cut. Serious injury or property damage could result from the motor starting inadvertently.
If the control surfaces do not respond as shown, DO NOT FLY. Refer to the Troubleshooting Guide for more informa-tion. If you need more assistance, contact the appropriate Horizon Hobby Product Support department.

1. Power on the transmitter.

2. Turn on throttle cut.

3. Set the flight mode switch to Experienced Mode.
   IMPORTANT: Do NOT check the controls in the Beginner or Intermediate Modes.

4. Place the model on level ground away from obstacles.

5. Power on the aircraft, and wait for it to fully initialize.

6. Move the sticks on the transmitter as shown in the table and observe the control surfaces on the aircraft. Ensure the aircraft control surfaces respond as shown and return to neutral when the control input is released.

7. Check for any binding in the control surfaces.
   TIP: The transmitter emits a faint beep with each click of the trim buttons in either direction. Holding the button in either direction quickly adjusts the trim several steps until the button is released or until the trim reaches the end of its travel. If the trim button does not beep when clicked, the trim is at the far end of its travel. Center trim is indicated by a slightly louder beep.

Control Centering

Before the first flights, or in the event of an accident, make sure the flight control surfaces are centered. Ad-just the linkages mechanically if the control surfaces are not centered, avoid excessive use of transmitter sub- trims. Control surface centering must be done with SAFE off, and AS3X not active. Keep the throttle at zero after powering on to prevent AS3X from activating.
IMPORTANT: Enable throttle cut to help prevent accidental throttle activation.

1. Verify the trims and subtrims on your transmitter are neutral.
2. Connect a battery to the model with SAFE off and keep throttle at zero.
3. When needed, use a pair of pliers to carefully bend the metal linkage (see illustration).
4. Make the U-shape narrower to make the linkage shorter. Make the U-shape wider to make the linkage longer.

Centering Controls After First Flights
For best performance with AS3X, it is important that excessive trim is not used. If the aircraft requires exces-sive transmitter trim (4 or more clicks of trim per channel), return the transmitter trim to zero and adjust the linkages mechanically so that the control surfaces are in the flight trimmed position.

Control Horn Settings

• The illustration shows the factory settings for the control horns. Fly the aircraft at factory settings before making changes.
• After flying, you may choose to adjust the linkage positions for the desired control response.
  CAUTION: When these are incorrectly connected for the pilot’s skill level, unexpected aircraft response to controls can result. This can cause damage to the aircraft and personal injury.

Center of Gravity (CG)

The CG location is measured 43mm ± 3 behind the leading edge of the wing. This CG location has been deter-mined with the recommended 150mAh 1S 3.7V 50C Li-Po battery (SPMX1501S50) installed to the front edge of the battery tray. 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.

Flying Tips and Repairs

WARNING: Always engage throttle cut before approaching the aircraft.

Range Check the Radio System
Range check the radio system with the aircraft. Refer to your specific transmitter instruction manual for range test information.

Flying
We recommend flying your aircraft outside in no greater than a light breeze or inside in a large gymnasium. Always avoid flying near houses, trees, wires and buildings. You should also be careful to avoid flying in areas where there are many people, such as busy parks, schoolyards or soccer fields. Consult local laws and ordinances before choosing a location to fly your aircraft.

Takeoff
Place the aircraft in position for takeoff (facing into the wind if flying outdoors). Set dual rates to low position and gradually increase the throttle to ¾ to full and steer with the aileron stick. Pull back gently on the elevator and climb to check trim. Once the trim is adjusted, begin exploring the flight envelope of the aircraft.

Landing

• Always land into the wind. During the flare, keep the wings level and the aircraft pointed into the wind. Slowly lower the throttle while easing back on the elevator to bring the aircraft gently down on all three wheels.
  NOTICE: Always fully lower the throttle at touch down when landing the aircraft to prevent damage to the propeller and motor.

• Failure to lower the throttle stick and trim to the lowest possible positions during a crash could result in damage to the ESC in the receiver unit.

Over-Current Protection (OCP)
The aircraft is equipped with over-current protection. OCP protects the ESC from overheating and stops the motor when the transmitter throttle is set too high and the propeller cannot turn. OCP will only activate when the throttle is positioned just above 1/2 throttle. After the ESC stops the motor, fully lower the throttle to re-arm the ESC.

Repairs
Crash damage is not covered under warranty. Repair this aircraft using foam- compatible CA glue or clear tape. Only use foam-compatible CA glue as other types of glue can damage the foam. When parts are not repairable, see the Replacement Parts List for ordering by item number.

Hand Launching

Grip
We recommend holding the aircraft on the bottom of the fuselage, just behind the wings, as shown.

Follow Through
Use a gentle toss with the wings level and the nose of the model slightly upwards. Avoid an arcing toss which can pull the nose down at release.

Post Flight Checklist

• Disconnect the flight battery from the ESC (Required for safety and battery life).
• Power OFF the transmitter.
• Remove the flight battery from the aircraft.
• Store the flight battery apart from the aircraft and monitor the battery charge.

Power System Servicing

Disassembly
CAUTION: DO NOT handle the propeller while the flight battery is connected to the ESC. Personal injury could result.
Rotate the propeller assembly and propeller adaptor assembly to remove it from the main gear. The motor and gear remain mounted to the main gear.

Assembly
Replace the propeller assembly and propeller adaptor assembly back onto the main gear, and rotate it ¼ turn until it snaps into place.

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 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.
