How do you guys calibrate non-kiss ESC in Kiss FC using Kiss firmware (or BLHELI)?

I had a maiden today it's my new build and had terrible oscillations. After a flip or roll quad was cutting motors and it was falling out of the sky. I have assigned kiss FC min and max throttle values in BLHELI. Any ideas ?

You can actually calibrate the esc's on the motors tab in blheli the same way you do in Cleanflight.

Or you can do it manually by setting up the numbers

set min throttle to 2000 and save
arm the quad and then plug in the lipo
wait for the calibration beeps then disarm- let the calibration finish
unplug
now set the min throttle to 1070 and save

Thanks. Would it be possible that desync and cutting off motors was caused by that ?

if you go 0 throttle in the air does it just wobble instead of still letting you have control? If not then it's not the same issue i think...
