The barometer is on the bottom side of the board so if your build allows sandwich a square of open cell foam between the board and the plate it’s mounted to. That’s what I have done with this FC and a F4 Nano. This type of foam is often used for packing material.
I followed all your recommnedations, checked everything with the wiki again and made today the second maiden flight. The result turns out to be fantastic. The copter behaves very good and can be steered easily and correctly. I started in stabilized mode and went trough loiter and alt_hold. I now have enough data to analyze for fine tuning and then to prepare for GPS modes.
Kind regards,
Andreas
P.S. If needed I can upload a video from the maiden flight in loiter as well as the logs.
