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 is not receiving a proper arming signal or there is a safety issue. First, check that your transmitter and receiver are correctly bound and that the throttle stick is at its lowest position. Many ESCs require the throttle to be at zero to arm. Next, ensure the ESC calibration is correct: power up the ESC while holding the throttle at maximum, wait for the beep sequence, then lower the throttle to the minimum to set endpoints. Also, verify the battery voltage is within the ESC’s safe operating range and that all wiring is secure with no shorts. Some ESCs beep to warn of overheating or low voltage, so measure the temperature and battery voltage to rule these out. Finally, consult your ESC’s manual for specific beep codes, as they vary between models. Following these steps should help your ESC arm correctly and stop the beeping.
