6. Operating Instructions
6.1. Basic Flight Controls
- Take-off/Landing: Use the one-key take-off/landing button for automated ascent and descent.
- Ascend/Descend: Control the left joystick (throttle) to adjust altitude.
- Forward/Backward: Control the right joystick to move the drone forward or backward.
- Turn Left/Right: Control the left joystick (yaw) to rotate the drone clockwise or counter-clockwise.
- Sideward Flight: Control the right joystick to move the drone left or right sideways.
6.2. Advanced Flight Features

- Altitude Hold: The drone can automatically lock its altitude and position, allowing the pilot to focus on camera control without constantly adjusting the throttle. This feature provides stable hovering for clearer photos and videos.
- One Key Return: With the one-key return system, the drone can automatically fly back to its take-off point, reducing the risk of loss due to improper control or signal issues.
- Track Flight (Trajectory Flight): Draw a desired flight path on your smartphone screen, and the drone will automatically follow this route, capturing footage along the way. This enhances the flight experience by allowing pre-planned aerial maneuvers.
- Gesture Recognition (Photo/Video): Perform specific hand gestures in front of the drone's camera to trigger photo capture (e.g., "Victory" gesture) or video recording (e.g., "Palm" gesture). This offers a convenient way to take selfies or start recording without touching the remote controller.
- Real-time Transmission (FPV): Connect your smartphone to the drone via Wi-Fi to receive a live video feed from the 4K camera. The FPV range is up to 80 meters, providing an immersive flying experience.
- Headless Mode: In Headless Mode, the drone's orientation is irrelevant; it will move relative to the pilot's position. This simplifies control, especially for beginners.
- Emergency Stop: In case of an emergency or loss of control, activate the emergency stop function to immediately power down the drone's motors.
- 3D Flip: Perform acrobatic 3D flips with a press of a button, adding excitement to your flight.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Drone does not power on. | Battery not installed correctly or discharged. | Ensure battery is fully charged and properly inserted. |
| Remote controller does not power on. | AAA batteries are dead or incorrectly installed. | Replace AAA batteries, ensuring correct polarity. |
| Drone does not respond to controls. | Not paired with remote controller, out of range, or interference. | Re-pair the drone and controller. Ensure you are within the 150m operating range. Avoid areas with strong Wi-Fi signals. |
| Poor image/video quality or no FPV feed. | Weak Wi-Fi signal, too far from drone, or app issue. | Ensure smartphone is connected to the drone's Wi-Fi. Fly closer to the drone (within 80m FPV range). Restart the app and drone. |
| Short flight time. | Battery not fully charged, old battery, or aggressive flying. | Fully charge the battery. Consider replacing old batteries. Fly more conservatively. |
| Drone drifts during flight. | Calibration needed or environmental factors (wind). | Perform gyroscope calibration as per the drone's specific instructions (usually a joystick combination). Fly in calm conditions. |
