- Einschalten: Schließen Sie den Drohnenakku an. Der Flugcontroller wird initialisiert.
- Bewaffnung: Arm the drone using your configured switch on the remote controller. Ensure propellers are clear before arming.
- Flugmodi: Select desired flight modes (e.g., Acro, Angle, Horizon) via your remote controller.
- OSD-Informationen: Batterievol überwachentage, current draw, flight time, RSSI, and other data displayed on your FPV goggles or monitor.
6. Wartung
To ensure the longevity and reliable performance of your iFlight SucceX-D F7 TwinG Flight Controller, follow these maintenance guidelines:
- Sauber halten: Regularly inspect the board for dust, dirt, or debris. Use compressed air or a soft brush to gently clean the components.
- Feuchtigkeit vermeiden: Protect the flight controller from water and excessive humidity. If exposed to moisture, ensure it is completely dry before powering on.
- Verbindungen prüfen: Periodically check all soldered joints and connectors for looseness or damage. Re-solder or replace as necessary.
- Firmware-Updates: Keep the BetaFlight firmware updated to benefit from performance improvements and bug fixes.
- Physischer Schutz: Consider using a protective enclosure or conformal coating for added durability, especially in harsh environments.
7. Fehlerbehebung
If you encounter issues with your flight controller, consider the following troubleshooting steps:
- Kein Strom/LEDs aus:
- Überprüfen Sie den Batterieanschluss und die Lautstärketage.
- Inspect power cables for damage or incorrect polarity.
- Verify BEC output if powering other components.
- No Connection to BetaFlight Configurator:
- Ensure USB Type-C cable is fully inserted and functional.
- Installieren Sie die erforderlichen VCP-Treiber (Virtual COM Port).
- Probieren Sie einen anderen USB-Anschluss oder Computer aus.
- Instabiler Flug:
- Recalibrate accelerometers in BetaFlight.
- Check for loose mounting or vibrations affecting the gyros.
- Verify PID settings are appropriate for your drone setup.
- OSD wird nicht angezeigt:
- Ensure OSD is enabled in BetaFlight and configured correctly.
- Check VTX and camera connections.
- Empfänger antwortet nicht:
- Verify receiver wiring to the correct UART.
- Ensure the correct serial receiver protocol (e.g., SBUS, Crossfire, Spektrum) is selected in BetaFlight.
