3. Setup

3.1. Package Contents

The package typically includes the following items:

• Helicopter
• Remote Control
• Lipo battery
• USB charger
• Phillips screwdriver + hex wrench
• Propeller / tail rotor (spare parts)
• Instruction manual

Refer to the diagram on page 3 of the manual for a visual representation of the package contents.

3.2. Remote Controller Battery Installation

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

Refer to the diagram on page 7 of the manual for a visual guide to battery installation.

3.3. Battery Charging

Using the original factory USB charger ensures charging safety. Other chargers may cause battery damage. The blue light ladder flashes during charging, and all four lights are solid when fully charged.

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

Refer to the diagrams on page 6 of the manual for illustrations of the charging methods.

3.4. First Flight Preparation

1. Ensure sufficient power supply for both the transmitter and the helicopter.
2. Choose a suitable open space for flight, 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 rotor rotation. (Note: This action may cause a helicopter crash.)

Refer to the diagram on page 6 of the manual for a visual representation of flight preparation.

Refer to the diagram on page 4 of the manual for a detailed view of the helicopter parts.

4.3. Direction of Operation (Controls)

If you are new to RC helicopters, take some time to familiarize yourself with the controls before your first flight.

• Throttle (Left Stick Up/Down): Up for ascent, Down for descent.
• Climb/Descend (Left Stick Up/Down): Controls vertical movement.
• Rudder (Left Stick Left/Right): Left for counter-clockwise rotation (nose yaws left), Right for clockwise rotation (nose yaws right).
• Elevator (Right Stick Up/Down): Up for forward flight, Down for backward flight.
• Aileron (Right Stick Left/Right): Left for left side fly, Right for right side fly.

Refer to the diagrams on page 7 and 8 of the manual for visual representations of control inputs.

4.4. Flight Operation Steps

1. Turn on the transmitter and place the helicopter near it.
2. Install the aircraft battery safely and securely in its compartment. Press the power switch on the aircraft for 2 seconds to turn it on.
3. The helicopter and remote control lights will flash simultaneously. Quickly push the throttle stick from top to bottom. The remote control will emit a 'DI' sound, and both indicator lights will become solid, indicating successful binding.
4. To start the helicopter, push both joysticks to the outer eight angles simultaneously. Alternatively, press the one-key takeoff button.
5. Keep the helicopter's head facing forward and maintain a safe distance from it.
6. When manually landing, keep the throttle stick at the bottom for 2-3 seconds until the propellers completely stop rotating before releasing the stick. (This step is not needed for one-key landing.)
7. For taking photos or recording videos, the APP must be connected.

Note:

• To avoid injury, do not look at the helicopter at hip level during flight.
• To avoid distractions, ensure no other transmitters are operating nearby during binding.

Refer to the diagrams on page 8 of the manual for visual steps.

4.5. Flight Yaw Correction Method

If the helicopter yaws or does not hover stably, follow these steps to adjust:

1. Enter fine-tuning mode by pushing the throttle stick down for 3 seconds.
2. Control the throttle to take off.
3. Observe the current yaw direction of the aircraft.
4. Adjust the joystick in the opposite direction of the yaw until the helicopter hovers smoothly.
5. Press the spinner button down to save the setting.

Refer to the diagrams on page 9 of the manual for visual guidance on yaw correction.

4.6. Gyro Calibration Method

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

1. Place the aircraft on a level ground for calibration.
2. During calibration, the indicator light will flash quickly.
3. Once calibration is complete, the indicator light will stop flashing, and you can take off.

Trimming Notes: Maintain a flying altitude above one meter during trimming.

Refer to the diagrams on page 10 of the manual for visual steps.

4.7. APP Operating Guide

To use the APP features, install the mobile phone client by scanning the QR code provided in the manual.

1. Turn on the product power switch.
2. On your phone, go to "Settings" and enable Wi-Fi.
3. Find the device's Wi-Fi hotspot in the list and connect to it.
4. Open the APP, tap the start icon to enter the real-time interface.
5. Tap the "ACTIVATE" icon to enter the real-time control interface and control the aircraft using the APP.

Scene Application Identification (C127 AI specific, identifies 80 types of targets):

• Set the desired function within the image recognition settings in the APP.
• Lock onto a target for shooting (note: in light wind, the helicopter may rotate to follow but cannot follow forward/backward).
• Simulate human movement posture to identify body direction for more interactive fun.

Refer to the diagrams on page 5 of the manual for APP interface and scene recognition examples.

5. Maintenance

5.1. Parts Replacement Instructions

• Propeller Replacement: Use a hex wrench to remove the propeller. Ensure smooth rotation. Match 'A' blades with 'A' positions and 'B' blades with 'B' positions for balance. Do not overtighten.
• Tail Rod Replacement: First, disassemble the housing, then remove the tail motor plug. Pull the tail rod out backward, paying attention to the installation direction. After installing the new tail rod, fix the machine shell screws. When fixing the screws, ensure the tail skid direction is vertical and not deflected.
• Tail Rotor Replacement: Pay attention to the direction. Align with the motor shaft and press slowly to ensure smooth rotation.
• Steering Gear Replacement: Pay attention to the connecting rod direction.
• Other Internal Parts: Pay attention to the installation order and position.

Refer to the diagrams on page 11 of the manual for visual guidance on parts replacement.

8. User Tips

• Beginner-Friendly: Many users find these helicopters easy to fly and stable, making them suitable for beginners to learn heli flying.
• App Compatibility: The companion app may not be compatible with the latest Android versions (e.g., Android 15). This can affect video quality and color representation, especially for the AI version. Consider using an older device or a non-AI model if app features are critical for video.
• Video Quality (C127 AI): The C127 AI model's video feed might have color inversion issues (e.g., blue sky appearing yellow). If high-quality video is a priority, consider the C127 or C128 models without AI, or be aware of potential color discrepancies.
