@rts18 Any chance of posting some Diffs for various airframe types, would be useful for optimising the current default PID settings. Really just after the `nav_fw_pos_z ` and `nav_fw_alt_control_response `settings...

@Jetrell How did the DPS310 baro behave with no compensation, did it drift by several meters after 5 mins or so ? The spec sheet for it shows the same...

I've used the same method to compensate for IMU Acc Z drift which seems to work possibly more reliably than the Baro, the Auto calibration correction factor is much more...

Added temperature compensation for the accelerometer. Not so easy to check the affect during calibration so just check that a non zero setting value is returned after the 5 minute...

> @breadoven I forgot to mention it won't allow calibration of the ICM42605 IMU's. I tried a few of them... So I only tested FC's with MPU6000. As far as...

That sounds like the behaviour I'm seeing. Poshold will work OK for a while then suddenly lurch sideways and continue drifting for several meters. Altitude does the same when set...

> @breadoven what is the satatus of this one? We are planing a feature freeze for Nov 15. Should we target this to 8.1 or 9, or do you think...

This could be merged now I've added a sensors.md to describe how it functions. Should it be merged to Master or maintenance -8.x.x though ?

I'd have thought a crude form of wind measurement for a multirotor would just involve letting it hover in Angle. The ground drift should be equal to the wind speed...
