Can someone tell me how to calibrate ESC on kiss fc with the littlebees and rg20 ESC?

I succesfully built a quad with kiss esc, but not sure if these combos need the same calibration or i have to setup the esc first in blheli (ppm ranges)

The steps in the manual are missing a few items.

After setting the Min Throttle to 2000, you save it and disconnect and then power up the board again.

Then Arm it with the switch followed by the LIPO connection. YOu'll get confirmation beeps.

Then Disarm it. If you don't get the confirmation beeps, Bump up your Min Throttle Command value by 5 points. Each receiver setting is slightly different. With my Spektrum Satellite, my Min Command had to be at 1085 or higher to get the disarm confirmation beeps of the ESC Calibration steps.

Also if the steps are still inconsistent in results, turn off Oneshot125 / 42 and then try the ESC Calibration steps again.

Don't forget to set your MinThrottle back to 1070 after getting the disarm confirmation beeps.

Note: On Power Up, you need to wait for the blue LED to turn OFF before trying arm it.
