I've noticed that the Arducopter holds much more stable altitudes in steady air than it does in wind.
On breezy days, the Arducopter will climb/fall spontaneously while in GPS Hold. In still air, it holds much better.
Should I be wrapping the barometric sensor in foam or something similar? Has anyone tried damping/insulating the barometer to get more stable pressure readings in Wind?
I can't say for sure this is the cause, as I have not seen the raw barometer readings. Is there an easy way to do that? I suspect they're all over the place when the Arducopter is tilting into the wind and gusts.
