2. GPS and Compass Calibration
For stable flight and accurate GPS functions, calibration is essential before each flight.

Figure 3: GPS Satellite Positioning and Return Home features.
- Follow the on-screen prompts in the app to perform compass calibration. This usually involves rotating the drone horizontally and then vertically.
- Wait for the drone to acquire sufficient GPS satellites (indicated by a solid GPS icon in the app).
3. Basic Flight Controls
- One-Key Take-off/Landing: Press the dedicated button on the remote controller or in the app for automatic take-off or landing.
- Throttle Stick (Left Stick): Control altitude (up/down) and yaw (rotate left/right).
- Directional Stick (Right Stick): Control forward/backward and left/right movement.
- Speed Modes: The drone supports slow gear (5m/s) and fast gear (8m/s) for varying flight experiences.
4. Intelligent Flight Modes
- Follow Me: The drone will automatically track your movement and capture video with a particular aerial view. Lock the human figure in the app, and the quadcopter will maintain a certain distance while tracking and shooting.

Figure 4: Drone utilizing the Follow Me function.
- Waypoint Flight: Tap points on the map within the app, and the drone will automatically fly along the designated path, allowing the pilot to focus on camera control.
- Point of Interest: Set a specific building or position as your point of interest, and the aircraft will continuously circle around the preset point.
