  • No Signal from Receiver: Confirm the receiver is properly bound to your transmitter. Check the receiver's wiring to the flight controller and ensure the correct UART is configured in the flight control software.
  • Motors Not Spinning: Ensure ESCs are calibrated and motor directions are correctly set in the flight control software. Check motor connections to the ESC. Verify that the arming sequence is correctly performed.
  • OSD Not Displaying: Check OSD settings in the flight control software. Ensure the video signal is correctly routed through the OSD.
  • Unstable Flight: Review PID settings in the flight control software. Ensure all sensors (gyroscope, accelerometer) are calibrated correctly. Check for physical damage to propellers or frame.
  • Connection Issues with PC: Try a different USB cable or port. Ensure the correct drivers are installed for the flight controller.

For persistent issues, consult online communities or the manufacturer's support resources.
