8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Helicopter does not respond to remote. | Low battery in helicopter or remote; not paired correctly. | Charge batteries; re-pair helicopter and remote (power off both, then power on helicopter first, then remote). |
| Helicopter drifts during flight. | Not calibrated on a flat surface; wind interference; trim settings incorrect. | Recalibrate on a flat surface; fly in calm conditions; use fine-tuning buttons on the remote to adjust trim. |
| Poor camera image/video quality. | Insufficient lighting; camera lens dirty; memory card issues. | Ensure good lighting; clean camera lens; check memory card for sufficient space and proper insertion. |
| Short flight time. | Battery not fully charged; old battery; aggressive flying. | Ensure full charge; consider replacing old batteries; practice smoother flying. |
| Propellers not spinning. | Obstruction; motor damage; low battery. | Check for obstructions; ensure batteries are charged; if problem persists, contact support. |
