i succeeded to calibrate the esc one time but when i unplug the lipo the caibration is gone

do you have some idea on what i do bad
Thank’s a lot for your time

Start here:

Then use the motor test to get the speeds set:

Make sure the props are off!!!

Also make sure you note that the motor test A,B,C,D is NOT the same as the motor order for installation.
