Question: Why does my ESC keep beeping and not arm?
Answer: Continuous beeping from your ESC usually indicates it hasn’t received the proper arming signal or there’s a setup issue. First, check your transmitter throttle stick is fully down when powering up the ESC, as many ESCs require this to arm. Next, ensure your receiver and ESC are correctly calibrated: power up the ESC with the throttle at max, wait for the tones, then lower the throttle to minimum to complete calibration. Also, verify your ESC’s battery connection and voltage are stable and within spec. If the ESC has a throttle cut or safety feature, make sure it’s disabled or properly configured. Finally, inspect all wiring for loose connections or shorts. Following these steps should resolve the beeping and allow the ESC to arm properly.
