Drifting Altitude

I have a newer build that is experiencing altitude drift. I did my initial tuning with a fixed brick payload that is slightly heavier than my camera/gimbal. That said, I’ve performed a Hover and Learn flight in Alt Hold mode and set PSC_ACCZ_I and PSC_ACCZ_P values according to documentation.

What am I missing here? The machine flies pretty well otherwise.

Thanks in advance!

I’m also experience an altitude drift with a DPS3100 and Arducopter 4.1.5. Did you find any solution?

I wiped the firmware and re-loaded. Works fine now.
