Ok, finally I built another quadcopter smaller than the previous one:
-F250 Multi-Copter Quadcopter Frame
-(4x)OCDAY RS2205 2205 2300KV 3-4S
-(4x)LittleBee 20A-S ESC BLHeli_S OPTO 2-4S
-(4x)propeller 5045
(I kept all the other components the same)

I use now IBUS instead of PWM, but the important thing is about ESC calibration. Now this little quadcopter flies!

The LittleBee ESCs they all come calibrated and I didnt need to do any solder or complex stuff to program them the firmware of BLHELI cause the already have it from factory.
So I recommend to not use hobbywing skywalker ESCs if you dont want to upgrade their firmware.

It was so easy to just check the configuration of the LittleBee ESCs, I really like them.
Thank you for the support and I hope this can help someone
