From stabilized to position strange behaviour

🧪 Flight Testing & Log Analysis

Hi guys,

On a F450 we have a strange behaviour when switching from stabilized to position

It shakes roll and pitch, even yaw turn a 1/4 turn, looses altitude, comes back and reposition itself.

Any idea?

Maybe mid throttle is not set correctly,
I have to admit I am not sure if barometer foam is correctly in place because altitude hold was not perfect, it is decending at mid stick…

Any idea?

Seems like it is related to the BARO foam that was too much compressed against Barometer.

Altitude was not good, etc.

Changed the foam, works correctly now.
