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 hasn’t received the correct arming signal or there’s a setup issue. First, check that your transmitter and receiver are bound and working properly. Next, ensure your throttle stick is at the lowest position before powering up the ESC, as many ESCs require this to arm. If the ESC still beeps, calibrate the throttle range by following the ESC manual: typically, this involves powering the ESC with the throttle at max, then lowering it to minimum when you hear specific beeps. Also, verify all motor and ESC connections are secure and correctly wired. If your ESC has a programming card or software, check the settings for throttle range and motor direction. Finally, confirm the battery voltage is within the ESC’s operating range. Following these steps should help your ESC arm correctly and stop the beeping.
