Title: Help needed for tuning PID in hyd Post by: AshwinRwt on January 08, 2015, 02:17:35 PM Hi, is there anyone in kompally area, Hyderabad, who could help me tune PI parameters of my quad (kk2.1 based).
Thanks Title: Re: Help needed for tuning PID in hyd Post by: sooraj.palakkad on January 08, 2015, 02:20:15 PM What is problem with your PI values ?
is the quad drifting on it's own ? Title: Re: Help needed for tuning PID in hyd Post by: AshwinRwt on January 08, 2015, 02:25:44 PM Its my first quad so I don't really know how it should behave, so I was wondering if someone with experience could check it out.
Well, the quad is drifting a lot on it own. Its a x525 arf kit from quadkopters.com. Title: Re: Help needed for tuning PID in hyd Post by: sooraj.palakkad on January 08, 2015, 02:31:50 PM Drifting is not related to PI dude, you have to trim your Transmitter channels to stabilize the quad.

Title: Re: Help needed for tuning PID in hyd Post by: sooraj.palakkad on January 08, 2015, 02:41:12 PM use trims to prevent quad from drifting . Let me assume you know how :headscratch:
tweak PI values only after Trimming it level . Title: Re: Help needed for tuning PID in hyd Post by: AshwinRwt on January 08, 2015, 02:44:25 PM Okey, how much altitude should I get before doing this? Ground turbulence is messing with the stability big time, I guess, because its a little stable 2 to 3 meters off the ground.
Title: Re: Help needed for tuning PID in hyd Post by: sooraj.palakkad on January 08, 2015, 03:11:23 PM Go to an open place with out trees or any obstruction near by, take off up to 10 mtrs height, and calmly trim it level,
