• Do not put any parts in the mouth; this can cause serious injury or death.
• Do not operate the model if the transmitter's battery is at low voltage.
• Do not look directly at the light-emitting diodes (LEDs), as it may affect eyesight.
• The motor and electric equipment will heat up after flight. Avoid touching them to prevent burns.
• To prevent damage, do not touch the high-speed rotating propellers.

Battery Usage Warnings and Guide

Using the original factory USB charger ensures charging safety. Using other chargers may cause battery damage and property damage.

Warnings! The battery will fire, explode, or leak if the following instructions are not strictly observed:

• Do not immerse the battery in water or seawater. Store the battery in a cool, dry environment during standby periods.
• Keep all batteries out of the reach of small children. Consult a doctor immediately if a battery is swallowed.
• Do not use or leave the battery near a heat source such as fire or a heater.
• Use the battery charger specifically designed for this purpose when recharging.
• Do not reverse the positive (+) and negative (-) terminals.
• Do not connect the battery to an electrical outlet.
• Do not dispose of the battery in fire or heat.
• Do not short-circuit the battery by directly connecting the positive (+) and negative (-) terminals with metal objects such as wire.
• Do not transport or store the battery together with metal objects such as necklaces, hairpins, etc.
• Do not strike or throw the battery against a hard surface.
• Do not directly solder the battery.
• Do not unpack the battery with a nail or other sharp object.
• Never disassemble the battery in any way.

Note: The battery should not be left at full power or low power for extended periods. Otherwise, it may not charge or may swell. For long-term storage, charge the battery to 3.7V and store it in a dry and safe place.

Setup

Package Contents

Ensure all items are present in the package:

• Helicopter
• Remote Control
• Lipo Battery
• USB Charger
• Phillips screwdriver + Hex wrench
• Propeller / Tail Rotor (spare)
• Instruction Manual

Remote Controller Battery Installation

1. Slide the battery lid open by following the arrow on the remote controller.
2. Insert 4 AA-sized batteries, ensuring correct polarity as indicated. Do not mix batteries of different chemistry or specifications.
3. Close the battery lid securely.

Battery Charging Method

The helicopter's Lipo battery can be charged using a USB charger. The red light on the charger indicates charging, and the light turning off indicates charging is complete.

1. Using a Computer USB Port: Connect the USB charger to a computer's USB port, then connect the helicopter battery to the USB charger.
2. Using a Power Supply Adapter: Connect the USB charger to a power supply adapter, then connect the helicopter battery to the USB charger.
3. Using a Power Bank: Connect the USB charger to a power bank, then connect the helicopter battery to the USB charger.

First Flight Preparation

1. Ensure sufficient power supply for both the transmitter and the helicopter.
2. Choose a suitable flight space, away from traffic, people, electricity pylons, and water bodies.
3. Do not overtighten the main rotor screws; they should allow the rotor to fold smoothly. Overtightening can cause the helicopter to shake during flight.
4. In an emergency, you can press the 'sharp stop' button for 3 seconds to land the helicopter without rotating. (Note: This action may cause a helicopter crash.)

Operating Instructions

Transmitter Function Overview

The remote controller features:

• Power Indicator: Shows the power status.
• One Key Take Off/Landing: Press this button for automatic take-off or landing. Long press and then power on for left/right throttle mode switch.
• Power Switch: Turns the remote controller on/off.
• Speed Button: Adjusts flight speed.
• Up, Down, Left, Right Rotation Joystick: Controls vertical movement and yaw.
• Forward, Backward, Left, Right Side Fly Joystick: Controls horizontal movement.
• Push up into 3D Tumbling Mode: Activates 3D flip mode.
• Fine-tuning Buttons: For precise adjustments to flight stability.
• LCD Display (Reserved): For displaying information.

Flight Operation Steps

1. Turn on the transmitter and keep the helicopter close to the transmitter.
2. Connect the battery to the helicopter.
3. The lights on both the helicopter and remote control will flash. Quickly push the throttle stick from top to bottom. The remote control will emit a 'DI' sound, and the indicator lights will become solid, indicating successful binding.
4. To start the helicopter, pull both joysticks to the outer eight angles. Alternatively, press the one-key takeoff button.
5. Keep the helicopter's head facing forward and maintain a safe distance from the helicopter.
6. For manual landing, keep the throttle stick at the bottom for 2-3 seconds until the propeller completely stops rotating before releasing. (This step is not needed when using the one-key landing function.)

Important:

• Do not look at the helicopter at hip level when it flies to avoid injury.
• Ensure no other transmitters are operating nearby to avoid interference during binding.

Direction of Operation

Familiarize yourself with the control directions before your first flight.

• Throttle: Up (climb), Down (descend).
• Rudder: Left (nose yaws left), Right (nose yaws right).
• Elevator: Up (forward), Down (backward).
• Aileron: Left (left side fly), Right (right side fly).

One-Key 3D Tumbling

To enter 3D roll mode, the aircraft must be at an altitude of more than 3 meters. The aircraft indicator light will flash quickly several times, indicating it's ready to perform 3D tumbling actions.

Flight Yaw Correction (Trimming)

If the helicopter exhibits yaw problems or unstable hovering, use the trimming buttons to adjust. Take off with the throttle joystick, and then press the fine-tuning button in the opposite direction of the yaw until the helicopter hovers steadily.

Gyro Calibration Method

1. If the helicopter yaws during flight, land it and calibrate the gyroscope.
2. During calibration, the aircraft must be placed on a level surface.
3. The indicator light will flash quickly during calibration and will become solid when calibration is complete, indicating it's ready for takeoff.

Maintenance and Parts Replacement

Parts Replacement Instructions

• Propeller: Remove with a hex wrench. When installing new propellers, do not overtighten.
• Tail Rod: Pull the plug backward forcefully. Pay attention to the direction during installation and align the power cord with the hole.
• Motor: Unplug the connector, then twist the motor left and right to pull it out.
• Servo: Pay attention to the connecting rod direction when disassembling and replacing the servo.
• Landing Gear: Pull out downwards. When installing, press into the corresponding holes.
• Receiver: Remove the double-sided tape. Align the new receiver with the edge of the rack and stick it tightly without skewing. Connect the servo and motor in the correct plug order.
• Big Gear: Pull out straight down. Pay attention to the direction when installing the new gear; the axis plane should align with the inner hole of the gear.
• Tail Rotor: Pay attention to the direction when removing and replacing. Align the motor shaft and press slowly to ensure smooth rotation.

User Tips

• For optimal flight, operate in calm, unwound conditions as wind can significantly affect control due to the helicopter's size.
• If initial stabilization is difficult, practice with trim adjustments. The helicopter can be very stable once trimmed correctly.
• The battery typically lasts 10-15 minutes in quiet mode. Consider purchasing additional batteries for extended flight time.
• The 3D Flip/stunt function is activated with a single click, allowing for easy 360° spins and maneuvers.
• This model is well-suited for beginners and those looking to start flying RC helicopters.
• For better visibility in the sky, some users have repainted their helicopters in fluorescent colors.
