• Right Stick (Mode 2): Controls Forward/Backward (Elevator) and Left/Right Side Fly (Aileron).
• Fine-tuning Buttons: Adjust trim for throttle, rudder, elevator, and aileron to correct unwanted drift.

4. Battery Information

4.1. Battery Safety Warnings

Failure to strictly observe these warnings may result in battery fire, explosion, or leakage.

• Do not immerse the battery in water or seawater. Store in a cool, dry environment.
• Keep batteries out of reach of children. If swallowed, seek medical attention immediately.
• Do not use or leave the battery near heat sources (fire, heater).
• Use only the specified battery charger for recharging.
• Do not reverse positive (+) and negative (-) terminals.
• Do not connect the battery directly to an electrical outlet.
• Do not dispose of the battery in fire or heat.
• Do not short-circuit the battery with metal objects.
• Do not transport or store the battery with metal objects like necklaces or hairpins.
• Do not strike or throw the battery against hard surfaces.
• Do not directly solder the battery.
• Do not unpack the battery with sharp objects.
• Never disassemble the battery.

4.2. Battery Charging Methods

Image: Diagram showing three methods for charging the helicopter battery: via computer USB, power adapter, and power bank.

Using the original factory USB charger ensures charging safety. Other chargers may cause battery damage.

1. Via Computer USB Port: Connect the USB charger to a computer's USB port, then connect the battery. Blue lights will flash while charging; four solid lights indicate full charge.
2. Via Power Supply Adapter: Connect the USB charger to a power adapter (e.g., phone charger), then connect the battery. Blue lights will flash while charging; four solid lights indicate full charge.
3. Via Power Bank: Connect the USB charger to a power bank, then connect the battery. Blue lights will flash while charging; four solid lights indicate full charge.

Note: Do not store the battery fully charged or completely discharged for long periods. For long-term storage, charge the battery to 3.7V and store it in a dry, safe place.

5. Setup

5.1. Installing Transmitter Batteries

Image: Diagram showing how to open the battery compartment and insert AA batteries into the remote control transmitter.

1. Slide the battery lid open in the direction of the arrow.
2. Insert 4 AA-sized batteries, ensuring correct polarity (+/-). Do not mix batteries of different chemistry or specifications.
3. Close the battery lid securely.

5.2. First Flight Preparation

Image: Diagram illustrating pre-flight checks, including ensuring sufficient power and checking main rotor screw tightness.

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

6. Operating Instructions

6.1. Flight Operation Steps

Image: Diagram showing the sequence of steps for starting and binding the helicopter with the remote control.

1. Turn on the transmitter and place the helicopter near it.
2. Install the helicopter battery securely in its compartment. Press the helicopter's power switch for 2 seconds to turn it on.
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 make a 'DI' sound, and both indicator lights will become solid, indicating successful binding.
4. To start the helicopter, pull both joysticks to the outer eight angles simultaneously. Alternatively, press the one-key take-off button.
5. Keep the helicopter's head facing forward and maintain a safe distance.
6. For manual landing, keep the throttle stick at the bottom for 2-3 seconds until the propeller stops rotating completely, then release it. (This step is not needed for one-key landing).

Note:

• Do not look at the helicopter at hip level during flight to avoid hitting it.
• Ensure no other transmitters are operating nearby to avoid interference.

6.2. Control Directions (Mode 2)

Image: Diagram illustrating the effects of moving the throttle and rudder sticks on the helicopter's movement.

Image: Diagram illustrating the effects of moving the elevator and aileron sticks on the helicopter's movement.

Familiarize yourself with these controls before your first flight:

• Throttle (Left Stick Up/Down): Controls altitude (Throttle Up = Climb, Throttle Down = Descend).
• Rudder (Left Stick Left/Right): Controls yaw (Rudder Left = Nose Yaws Left, Rudder Right = Nose Yaws Right).
• Elevator (Right Stick Up/Down): Controls forward/backward movement (Elevator Up = Forward, Elevator Down = Backward).
• Aileron (Right Stick Left/Right): Controls side-to-side movement (Aileron Left = Left Side Fly, Aileron Right = Right Side Fly).

6.3. Flight Yaw Correction

Image: Diagram showing how to use the fine-tuning buttons on the transmitter to correct unwanted yaw (drift) in forward/backward, left/right, and side-fly directions.

If the helicopter drifts or has unwanted yaw during hover, use the fine-tuning buttons:

1. Take off the helicopter using the throttle joystick.
2. Observe the direction of yaw.
3. Press the fine-tuning button on the transmitter in the opposite direction of the yaw until the helicopter hovers stably.

6.4. Gyro Calibration

Image: Diagram illustrating the process of calibrating the gyroscope, emphasizing the need for a level surface.

If the helicopter yaws during flight, land it and calibrate the gyroscope:

1. Place the aircraft on a perfectly level ground.
2. Initiate gyro calibration (refer to transmitter manual for specific button combination, usually by moving both sticks to a specific corner).
3. The indicator light will flash quickly during calibration. It will stop flashing and become solid when calibration is complete, indicating it's ready for take-off.

7. Maintenance

7.1. Commonly Used Parts Replacement

Image: Diagrams showing how to replace the propeller, motor, main gear, and tail rotor.

• Propeller Replacement: Use a hex wrench to remove the old propeller. Be careful not to overtighten when installing the new one.
• Motor Replacement: Unplug the motor, then twist it left and right to pull it out.
• Main Gear Replacement: First, remove the screw, then pull the big gear directly downward. Pay attention to the direction when installing the new gear; the plane of the shaft should align with the plane of the inner hole of the gear.
• Tail Rotor Replacement: Pay attention to the direction when removing and replacing the tail rotor. Align the motor shaft and press it slowly to ensure smooth rotation.
