5. Maintenance

5.1 Cleaning

Regularly clean the drone's body and propellers with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or excessive moisture.

5.2 Propeller Replacement

If a propeller is damaged, replace it with a spare. Use the provided screwdriver to carefully remove the screw holding the damaged propeller. Replace it with a new one, ensuring you match the correct propeller type (A or B) to the corresponding motor arm, and secure it with the screw.

5.3 Storage

When not in use, fold the drone arms and store it in a cool, dry place away from direct sunlight and extreme temperatures. Ensure batteries are partially charged (around 50%) for long-term storage to maintain battery health.

6. Troubleshooting

6.1 Drone Drifts During Flight

If the drone drifts to one side, perform a gyro calibration as described in Section 4.3. If drifting persists, use the trimming buttons on the remote control to fine-tune its stability. Press the trim button opposite to the direction of drift until the drone hovers steadily.

6.2 App Connection Issues

Ensure the drone is powered on and your smartphone is connected to the drone's Wi-Fi network. Verify that the "SOTAONE FPV" app has all necessary permissions enabled (Local Network, Wireless Data, Microphone, Photos) in your phone's settings. If the issue persists, try restarting both the drone and your smartphone.

6.3 Short Flight Time

Ensure batteries are fully charged before each flight. Flight time can be affected by aggressive flying, strong winds, and low temperatures. Consider using both included batteries for extended flight sessions.
