|The ESC didn’t work after it was powered on while the motor kept beeping.
|“BB, BB, BB……”
|The input voltage was beyond the operating voltage range of the ESC.
|Adjust the power-on voltage and ensure it’s in the operating voltage range of the ESC.
|-
|The ESC didn’t work after it was powered on while the motor kept beeping.
|“B-, B-, B-, B-……”
|The ESC didn’t receive any throttle signal from the receiver.
|Check if the transmitter and receiver are well paired, if any poor connection exists between the ESC and receiver.

|The ESC didn’t work after it was powered on while the motor kept beeping.
|“B, B, B, B……”
|The throttle stick has not been moved to the bottom position.
|Move the throttle stick to the bottom position and calibrate the throttle range.
|-
|The ESC didn’t work after the throttle calibration while the motor kept beeping.
|“B, B, B, B……”
|The throttle range you set was too narrow.
|Re-calibrate the throttle range.
|-
|The ESC output suddenly reduced to 60% during the flight, the motor kept beeping after the flight completed but the battery was still connected to the ESC.
|“BB, BB, BB……”
|The ESC thermal protection has been activated.
|Improve the heat dissipating condition (i.e. add a cooling fan) or reduce the ESC load.
|-
|The ESC output suddenly reduced to 60% during the flight, the motor kept beeping after the flight completed but the battery was still connected to the ESC.
|“BBB, BBB, BBB……”
|The low-voltage cutoff protection has been activated.
|Change another pack; lower down the cutoff voltage or disable the LVC protection (we do not recommend this).

'''1. Start-up Protection:''' The ESC will monitor the motor speed during the start-up process. When the speed stops increasing or the speed increase is not stable, the ESC will take it as a start-up failure. At that time, if the throttle amount is less than 15%, the ESC will try to restart automatically; if it is larger than 20%, you need to move the throttle stick back to the bottom position first and then restart the ESC. (Possible causes of this problem: poor connection/disconnection between the ESC and motor wires, propellers are blocked, etc.)
