6. Manteniment

• Inspecció periòdica: Periodically check all solder joints and connections for any signs of wear, corrosion, or damage.
• Neteja: Keep the flight controller and ESC free from dust, dirt, and moisture. Use a soft brush or compressed air for cleaning. Avoid using liquids directly on the electronics.
• Actualitzacions de firmware: Regularly check for new firmware releases for both the flight controller (BetaFlight) and ESC (BLHeli_32) to ensure optimal performance and access to new features.
• Emmagatzematge: Quan no l'utilitzeu, guardeu la pila en un lloc sec i fresc, allunyat de la llum solar directa i de temperatures extremes.

7. Solució De Problemes

• Sense energia: Check battery connection, XT60 power cable, and ensure the battery is charged. Inspect for any short circuits.
• No USB Connection: Ensure the Type-C USB cable is fully inserted and functional. Try a different USB port or cable. Verify that necessary drivers are installed on your computer.
• Motors que no giren: Check ESC connections to motors and flight controller. Verify ESC calibration and motor direction in BetaFlight. Ensure arming conditions are met.
• Vol inestable: Recheck mounting for proper shock absorption. Verify gyroscope calibration in BetaFlight. Review BlackBox logs for insights into vibrations or control issues.
• El receptor no respon: Confirm receiver is correctly wired to the flight controller. Check receiver protocol settings in BetaFlight (Sbus, PPM, CRSF, etc.). Ensure receiver is bound to your remote controller.

8. Consells d'usuari

• Optimal Gyroscope Performance: The unique shock absorption structure is crucial for the 42688-P gyroscope's stability. Ensure the silicone grommets are correctly installed and not overtightened to maximize vibration dampening and achieve a 'silky smooth flight experience'.
