Did not try it yet, looking at the unfiltered data to see the main frequencies.
Found to my dismay, that my ESC’s are not RPM locked, spoolups are locked on different RPMs. as i understand the governing mode is applicable only at 75-85%. Currently i’m at 65%.
Alas at lower RPM i get worse harmonics. modal frequencies ?
@bnsgeyer, latest development…
Heli 450 #1, with FlyBar, after long time of looking for the PSC reason to jump and be unstable… decided to change the GPS unit to an updated one, with capability of more GPS constellations… and Bingo … all is functioning well, for the first time i could leave the sticks and let the heli hold position by itself.
Dew to the long process, i think the heli is also better tuned.
