After power-on, the motor makes no sound (no "B" tone).

Possible cause: No battery power reaching the ESC, or reversed polarity. Fix: Check the battery-ESC connection and re-solder if loose. If polarity is reversed, disconnect power immediately—otherwise, the ESC may be damaged.

After power-on, the ESC does not respond, and the motor beeps "B--B--" every 2 seconds.

Possible cause: No throttle signal received from the receiver. Fix: Verify that the transmitter and receiver are properly bound, and check for any loose or broken connection between the ESC and receiver.

After power-on, the ESC does not respond, and the motor beeps "B-B-" every 200 ms.

Possible cause: Throttle range is set too narrow. Fix: Re-calibrate the throttle range.

During flight, power suddenly drops to 50%, and the motor beeps "B B-B B--" every 2 seconds.

Possible cause: ESC thermal protection has been triggered. Fix: Improve cooling (e.g., add a heatsink or fan), or reduce the load on the ESC.

During flight, power suddenly drops to 50%, and the motor beeps "B B B--B B B--" every 2 seconds.

Possible cause: Low-voltage cutoff (LVC) protection has been activated. Fix: Replace the battery pack, lower the cutoff voltage setting, or disable LVC (not recommended).
