I want to add filters to my copter since I noticed some vibrations. Most vibrations are below 10m/s/s. I followed all the docs for setting up FFT. When I try to do a FFT analysis in fftui its showing a really low frequency input like 24Hz. I’ve enables In-Flight FFT and also tried to run it through MavProxy but it outputs “extracted 0 fft data sets”. Are there any params I am missing or have set incorrectly? This is a fairly large multicopter with 18" props.
I attached my PARAM file.
