Hi, we have a matek f405mini te board in 4in indoor drone. we usually have some issues with the baro readings, even making some baro isulation foams installed.
the drone ascends slowly with the centered throttle stick. we have to down the throtlle stick each few seconds to maintain altitude.
we have done the baro temperature calibration and dont fix the issue.
we have a rc channel to enable rangefinder an loiter by optical flow. but in normal flight, we dont use rangefinder to can fly over obstacles without the drone upwards.
