Hi @xfacta, you actually have helped me with the tuning previously with these quads here: Tuning a fleet of large quadrotors. Interesting that the PID tune is still the problem… they seem to be very stable and responsive with the current tune.
You can find a log with pre-filter data there, I believe. I can create a new one of course.
Reviewing my notes, the logs in this thread are from quad # 4 and # 1. I may not have updated # 1 all the way with the latest tune and HNOTCH and whatnot.
