5. Operating Instructions
5.1 Pre-Flight Checklist
- Ensure all batteries are fully charged.
- Check propellers for damage and ensure they are securely attached.
- Verify the drone arms are fully unfolded.
- Confirm the drone and remote controller are paired and connected to the app.
- Perform compass calibration as instructed by the app or manual before the first flight in a new location.
- Choose a safe, open flying area.
5.2 Basic Flight Controls
- Takeoff/Landing: Press the one-key takeoff/landing button on the remote controller or use the app. Alternatively, push both joysticks down and out to start motors, then push the left joystick up to ascend.
- Ascend/Descend: Left joystick up/down.
- Turn Left/Right (Yaw): Left joystick left/right.
- Forward/Backward: Right joystick up/down.
- Fly Left/Right (Strafe): Right joystick left/right.
5.3 GPS Mode
When GPS signal is strong (indicated by GPS icon on remote/app), the drone will automatically maintain its position and altitude. This mode enables intelligent flight functions.
5.4 Optical Flow Positioning
The bottom optical flow sensor allows the drone to maintain a stable hover indoors or in areas with weak GPS signal. Ensure good lighting and a textured surface below for optimal performance.

5.5 Headless Mode
In Headless Mode, the drone's orientation is relative to the pilot, regardless of which way the drone's front is facing. This simplifies control for beginners. Activate via the remote controller button.
5.6 Intelligent Flight Functions (GPS Required)
- Smart Return Home (RTH): The drone will automatically return to its takeoff point if the battery is low, signal is lost, or the RTH button is pressed.
- Follow Me: The drone will automatically follow the remote controller or mobile device, keeping you in the frame.
- Waypoint Flight: Draw a desired flight path on the app map, and the drone will fly along it automatically.
- Surround Shooting: Select a point of interest on the app, and the drone will circle around it, capturing footage.

5.7 Obstacle Avoidance
The drone's obstacle avoidance system uses sensors to detect obstacles in its path and automatically adjust its flight trajectory to prevent collisions. This feature enhances flight safety.
5.8 Camera and Video Recording
The 4K UHD camera with a 2-axis gimbal provides stable and high-quality aerial footage.
- Adjust Camera Angle: Use the dedicated button/dial on the remote controller to adjust the camera's tilt angle (90° range).
