5. Gweithrediad

5.1 Rheolwr Hedfan

Once the FC is correctly wired and flashed with your preferred firmware (Betaflight, INAV, or Ardupilot), connect it to your computer via USB. Use the corresponding configurator software to perform initial setup, calibrate sensors, configure modes, and tune PID settings for optimal flight performance.

5.2 Electronic Speed Controller (ESC)

The GOKU G45M 4in1 ESC supports BL32 and AM32 firmwares. Ensure your ESC firmware is compatible with your FC firmware and motor protocol (Dshot300, Dshot600, Dshot1200). Calibrate your ESCs if required by your chosen firmware.

5.3 10V Switchable BEC

The integrated 10V BEC can be activated or deactivated via user modes, which is crucial for preventing VTX overheating during drone debugging or specific flight conditions. Configure this setting within your flight control software.
