Hi Craig,
I tried to calibrate the ESCs step by step by your instructions using joystick. But it did not work for me, because when I do Kill ArduCopter commands (step 5), the connection to the GCS is lost, and therefore I can not Set Joystick throttle to max (step 6). I clicked on the link Cannot calibrate ESC and connect to GCS simultaneously, but I did not find a solution there because in that case I don’t use the RC
I appreciate all the help I can get.
And in step 5 is this button need click?“Click ESC Calibration Button in Mission Planner”
