Hello everyone,
I recently switched from Inav to arducopter and arducopter stock PID not suit my quad, ones I got previously on Inav wer perfect but it doesn’t look like the same kind of values (there is a picture of my inav settings)
Is there a way to “translate” PID’s from Inav to Arducopter PID’s values?
Thank you
No the systems are too different.
You have to start over
So sad but thanks for the answer! 
If you describe your quad in detail, maybe we can suggest a starting point, then there is some tuning procedures to follow. With Ardupilot there are so many different choices and hardware possibilities that tuning is not a simple few mouse clicks and couple of test flights (but it can be when you are experienced)
After the calibrations, set up voltage monitoring then use MissionPlanner Initial Parameters to put in place most things you need to do a test flight and start adjusting PIDs for stable flight.

It’s easy enough to set up the Harmonic Notch Filter, then probably run Autotune.
The 7" Tuning thread is full of knowledge too, maybe too much!
