Phantom 2 baro problem

[kosmarnik]

Hi,

started flying again with the recent nice weather we got here.
I noticed that the quad isn't holding altitude as good as before.
I almost dunked it into water.
At 1m it was reading 3-4m.

Another test it almost landed by itself from 3-4m.

FW 3.08

Besides that it's behaving normally.

Any ideas how to troubleshoot?

OSD can be off by more than a couple of meters sometimes. Make sure your gains are at the default. Windy conditions can cause vertical oscillations as well.

My gains should be default, I'll double check.

Never had this issue and now it presented itself 2 times a different locations.
I know that OSD can be off, but this is dangerously off.

Did you do IMU calibration ? If you hover (no sticks touch) it does go down ? If yes... check and adjust to default GAINS.
