Motors got calibrated , I was able to run them And once I disconnect the lipo and re connect back again motors are beeping The throttle was down while powering back. Radio was calibrated before esc callibration! Still every time I power on motors beeps But if I press safety switch for 2seconds till solid red …motors gives callibrated sound And stops sounding. They r quiet. Once dis-connect lipo and reconnect …beeping restarts… What could be the issue?? ---

[![](https://img.youtube.com/vi/nm_HgdDpong/maxresdefault.jpg "motor beeping and can not calibrate motor how to fix safety switch") ](https://www.youtube.com/watch?v=nm_HgdDpong) This this thing helped me Disable safety switch, solved the issue of continuous motors beeping So what I realised is: motors beeping continuously is not an error but safety switch was preventing the fc to write minimum pulse to esc. When safety switch is long pressed, for 2 seconds motors gets activated as FC starts writing minimum pulse to esc By disabling safety switch FC starts writing minimum pulse right from start up(of course after 2seconds booting delay) ---
