Autotune issue?

Hi All,
I am trying to tune the ZOHD Talon GT Rebel because I am seeing many vibrations on the plane when flying in FBWA or AUTO. I tried Autotune and here is the log for Auto tune:

and a screenshot:

and here is the logs for the flights after:

I still saw the vibrations after the autotune, it was a windy day but not too bad… the vibrations did not improve a lot after the autotune…
I did autotune because of the recommendation of this thread:

Plane 4.1 Became unstable on Auto

I was flying the other day and set up a mission with take off. I am in Plane v.4.1.2 It seemed the whole mission went well, when I landed and wanted to do the mission again, I set the plane to Auto and if took off but it very quickly became unstable, like doing strange maneuvers and stalls that didn’t do in the first flight. I have reviewed the logs and it seemed that it started arming and disarming right after take off of the second time… I am not sure why it would do that but from my little …

I really don’t think the vibrations are normal, but not sure what could cause it since I’m new at this…
is it noisy gyro, faulty FC, needs more autotune time…?

Any help really appreciate it
Thanks in advance

Try the autotune with more patience on a less windy day first.

Good luck!!!

I have also struggled with AP 4.1.x autotuning the roll axis on my ZOHD Talon GT. Reducing RLL_RATE_SMAX and following the directions for tuning “light, agile aircraft” helped, but I still see intermittent high-frequency roll oscillations.
