I replaced one esc (out of four), esc that was replaced is working differently like starting before the other three, I have tried calibrating the escs all at same time and also individually using only the receiver and the transmitter, nothing helps. Hours just went into trying to crack this one, and nothing to show for it except a bunch of open tabs in browser, and headache from reading so much. I am using ardupilot apm2.8 flight controller, I have also tried to connect to the Cleanflight and BLHeli it doesn't connect .....please help..
