6. Solució De Problemes
6.1 Problemes comuns i solucions
- Sense alimentació/alimentació intermitent: Check all power connections, including the battery, XT60 connector, and BEC output. Ensure the input voltage is within the specified 3-6S range.
- Motors Not Spinning/Incorrect Direction: Verify ESC connections to the flight controller and motor wiring. Use the Betaflight/INAV configurator to check motor output and direction. Calibrate ESCs if necessary using Bluejay or BLHeliSuite.
- Sense pantalla OSD: Ensure the OSD module is correctly configured in Betaflight/INAV. Check video transmission connections (digital or analog) and ensure your FPV goggles/monitor are receiving a signal.
- Vol inestable: Review PID settings in Betaflight/INAV. Ensure the flight controller is securely mounted and vibration-isolated. Check for any loose propellers or damaged motors.
- El receptor no respon: Verify receiver wiring (SBUS/CRSF) and binding with your transmitter. Check receiver settings in the flight controller software.
7. Consells d'usuari
- For optimal performance, ensure proper vibration isolation for the flight controller. Use the provided silicone vibration absorbers.
- Always double-check wiring diagrams before making connections to prevent damage to components.
- Familiarize yourself with the Betaflight or INAV configurator software for advanced tuning and customization.
- Consider using a smoke stopper during initial power-up after assembly to prevent short-circuit damage.
