5. Operating Instructions
5.1 Pre-Flight Checklist
- Ensure batteries are fully charged.
- Check propellers for damage and correct installation.
- Verify stable GPS signal (if flying outdoors).
- Confirm successful connection between drone, remote, and app.
5.2 Calibration
Perform compass calibration before each flight, especially when flying in a new location. Follow the instructions in the app or the included manual for precise calibration steps.
5.3 Take-off and Landing
Use the one-key take-off/landing button on the remote or app for automated ascent and descent. For manual control, slowly push the throttle stick upwards to take off and downwards to land.
5.4 Flight Controls
Familiarize yourself with the remote control sticks and buttons. The left stick typically controls altitude and yaw (rotation), while the right stick controls forward/backward and left/right movement.
6. Maintenance
- Cleaning: Regularly clean the drone body and camera lens with a soft, dry cloth. Avoid using harsh chemicals.
- Propeller Replacement: If propellers are damaged, replace them immediately using the provided spare parts and screwdriver. Ensure correct A/B matching.
- Battery Care: Store batteries in a cool, dry place. Do not overcharge or over-discharge. If not used for extended periods, charge them to about 50% capacity.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Drone does not take off or flies erratically. | Improper calibration; damaged propellers; low battery. | Perform compass calibration; replace damaged propellers; fully charge batteries. |
| Video feed is choppy or disconnects. | Weak Wi-Fi signal; too far from controller. | Ensure strong Wi-Fi connection; fly within recommended range (approx. 100m). |
| Drone flies away when Return to Home is activated. | Not connected to satellite (GPS). | Ensure strong GPS signal before activating RTH. If it flies away, hit the RTH button again to regain manual control. |
| One motor not spinning. | Motor malfunction or debris. | Check for debris obstructing the motor. If issue persists, contact customer support. |
