Just question #14

Closed Legista closed 6 years ago

I am sorry for writing this in Issues, but i have no idea how to ask a question about this amazing Analyzer. I just can't understand how to interpret plot "xxx step response (>500)". What values are present in this plot and how they correlate with X axis and times on this axis. Why sometimes it appears, and sometimes not. I just can't get the point. Thank you! log00011tmp_0

Oh, it seems like i got it!. it's rate, right? I.e. blue line for rates lower than 500 and yellow for rates over 500 (deg/s?). And finally i understand this explanation "If D Setpoint Transition is set in Betaflight, your tune and thus the response will differ for high RC-inputs. This fact is respected by calculating separate responses for inputs above and below 500 deg/s. With just moderate input, you will get one result, if you also do flips there will be two." I am so stupid ))

:D yep, you got it right! You can probably increase D on roll to suppress the overshoot. And maybe up P on pitch for a sharper edge, but that's hard to tell.

I am starting to get a handle on this, but only just the beginnings. Plasmatree, your program is awesome, thank you very much.
