Hi,

Can't seem to get good PID's out of my quad. I always get vibrations when flying fast at low altitude. But much less vibrations at punch out.

My setup-
ZMR250V2, cobra 1960kv, 4S, DAL 6x4.5
Blackbox file- https://drive.google.com/file/d/0B8KR3wu0tAKhaWNtNjBCRXJEbWs/view?usp=sharing

Thanks!

As usual... it's your D term that is causing most of the noise... use this:

set dterm_lpf_hz = 40
