Sorry for many questions here but i am trying to learn from your experience. Can you please confirm if it is necessary or recommended to change ATC_RAT_RLL_FLTT & ATC_RAT_PIT_FLTT to ZERO when conducting the Autotune? I found this recommendation from @andyp1per here:
It would be great help to include this instruction in Autotune Documentation if this is the proper way.
I followed Tuning Process Instructions — Copter documentation and the FLTT values were set to 20 when Autotune was performed. I did not set FLTT to 0 for Autotune. Could this be the reason for a bad tune and a contributing factor for the crash?
Also The magnitude of Gyro noise as per the Post Filter FFT plot is really small. Can you please point towards another parameter to look at for the amount of noise instead of FFT Magnitude?
Many Thanks
