So auto-tune has usually worked pretty well for me, but I wanted to try manual tuning for fun. So raising the D term I’m looking for oscillations. Really? For P it’s obvious, but cranking the D term never makes my unit go crazy like a really high P and I. What am I looking for? As D increases you can tell it’s not flying well, but nothing dramatic. There’s a pulsing on the motors like it’s constantly hunting for the right rpm. I that it?
You saw this presumably? Manual tuning of Roll and Pitch — Copter documentation
D-term oscillation is quite high frequency
