Thanks for the log review, Allister. I’m glad you were able to get some confirmation on the FFT plot values. That is strange that your ubuntu install is having those issues.
I’ve been trying to find more info on the below ~25Hz guidance, and have had a little luck in this post Tuning the Harmonic Notch - #868 by andyp1per .
But I’m a bit confused on why you mention the 60Hz settings are better. When I look at those FFT plots, compared to the pre-harmonic notch plots, the 60Hz dynamic notch seems to have quelled the peak at about 136Hz, but a peak remains at 60Hz and I get couple other small peaks, so I end up with more peaks overall. However, when I look at the 136hz plots, it appears to have nearly eliminated an entire peak, resulting in less peaks overall in the plots. Wouldn’t this be more of an improvement? I’m wondering if the 60Hz is a frame resonance issue or something similar that would be better suited to a static notch.
I’m totally new to this process, so please forgive any misunderstandings.
Thanks for the tips on trying to improve vibration levels on the frame. My FC is also mounted on some of the DuBro vibration dampening foam to get the even close to acceptable levels of vibration right now. A new frame is on order - fingers crossed it arrives soon!
