Why does my ESC keep beeping and won’t arm?

Question: Why does my ESC keep beeping and not arm?

Answer: Continuous beeping from your ESC usually indicates it’s not receiving the correct arming signal. First, check that your transmitter and receiver are properly bound and powered on. Next, ensure your throttle stick is at the lowest position before powering up the ESC; many ESCs refuse to arm if the throttle isn’t fully down. If the ESC still beeps, calibrate the throttle range by following your ESC’s calibration procedure—this often involves powering up the ESC with throttle at max, then moving it to minimum after a beep sequence. Also, verify all motor and ESC connections are secure and that your battery voltage is within the ESC’s operating range. Finally, consult the ESC manual for specific beep codes, as different beep patterns can signal issues like low voltage, temperature warnings, or hardware faults. Following these steps should help your ESC arm properly and stop the beeping.
