Loss of altitude during FW transition (talisitter quadplane)

I have seen other posts about this and even posted an ask for help some time ago but have found no sound soution or suggestions. I have a tailsitter quadplane (no control surfaces) and experience a large loss of altitude during transition. See attached graph showing alt in green, nav/pitch in red and pitch in blue. Some info provided in other old threads reference TRIM_ARSPD_CM, which I have set to 1600cm/s, ARSPD_FBW_MIN which I have set to 25m/s and Q_TRAN_PIT_MAX which I have set to 3. None …
