Hello,
I did a trial/error PID tuning this last week-end for the following:
-Quadcopter (modified 3DR frame rev C base)
-APM2.5, 880Kv motors, 11x4.7 props
-4S 4500mah lipo
-Total weight (battery included) : 2,1 Kg (or about 4 pounds)
I did step by step modifications of the Roll/Pitch P value (with D, I at zero) and got a "happy" value around 17.
I then increased D and got a happy value at 0,011.
Not knowing how to tune I, I left it to the default 0,1 value.
I notice however that in windy conditions, the quad seems to have trouble to stay at the same spot. What parameter has an influence on that ?
Anyone with experience and who could share its "tuned" PIDs for a similar config as mine ?

I have a xaircraft frame with pretty top of the line components and a wookong controller.. and the wind really blows it around.. which I think has a lot to do with the side profile to which catches the wind. My TBS Discovery and F450 frames do amazingly well in the same wind. I also do have 14" blades on the large quad.. but not sure that is the reason for the issues with the wind. I am going to try out a higher battery voltage (5S) and smaller props.. but it probably is all about the side profile that catches the wind.
I was going to get another xaircraft frame for doing aerial surveying but after flying this week I am trying to work out a tilt/roll for my TBS frame.. I would hate to be more limited when I can fly due to the wind.
But I would love to know how you go about tuning the APM properly.
