Hi Everyone,
In this video I go through:
1. The theory of Betaflight filter tuning
2. How to set up gyro-scaled logging so you can look at your gyro noise
3. How to view those logs in Blackbox explorer to see your gyro noise
4. How to use the information to get your perfect filter tune first time every time!
This filter tuning approach is pretty much the same as that used by @uavtech. I didn't invent this but I hope that this explanation is helpful nonetheless.

If you want to run the lowest possible filtering check out my frame the AOS 5: https://youtu.be/DYTmbUuNps8
