hi,

would it "harm" my quad if I set the ROLL/PITCH/LEVEL I-terms to zero(0) ? I mostly fly my quad-X in stable mode. and in a few minutes after flying in that mode, it becomes "loosely coupled" esp when there has been many *adjustments* of the roll/pitch stick(usually when its a bit windy in the field). its sort of like a oscillator, the swaying starts small, then builds up until its uncontrollable that I just land it.sometimes crashes.

feels like im flying in STABLE mode w/c is slowly going to ACRO mode.that sort of thing...

If the roll/pitch I-terms are not zero, the quad IS crazy.. so HOW would I fix this problem?

If you look at the FAQ and read the link on PID tuning it tells you to start with I & D set to zero and adjust P until it oscillates, so going by that you should have no problem flying with I set to 0. Maybe you need to reduce P to improve stability so you can add in some I and D, PID tuning seems to be a matter of adjust fly, adjust fly, until you get it how you want it.

What version are you flying with? I have read of people having problems with V2 and stable mode but upgrading to the V2 dev their problems have gone away.

hey bill

thanks for the reply

regarding adjustment of PIDs, noted! THANKS

im running on dev20120522.. after reading a few more forum posts, Ive come across lowering value for RCRATE down to 0.6 (was previously at 0.9) .. now it has mellowed down a bit .. will test soon on the open field cuz its mostly raining, but I could see it has improved a bit...
