6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Drone does not power on. | Battery is not charged or not properly installed. | Charge the battery fully and ensure it is correctly inserted. |
| Remote control does not connect to drone. | Incorrect pairing sequence or interference. | Ensure both devices are powered on in the correct order (drone first, then remote). Move to an area with less interference. |
| Unstable flight or drifting. | Drone not calibrated or strong wind conditions. | Perform a calibration as per the remote control guide. Fly in calmer conditions. |
| Poor image/video quality. | Dirty camera lens, low light, or unstable flight. | Clean the camera lens. Ensure adequate lighting. Utilize optical flow positioning for stable shots. |
| Drone crashes into obstacles despite avoidance feature. | Obstacle avoidance sensors obstructed or operating in complex environments. | Ensure sensors are clean. Avoid flying in extremely dense or rapidly changing environments where sensors may struggle. |
