I see that.  Thank you.  But now, when I set the trim correctly the stabilizer returns to the full nose up position.  It doesn't hold the trim as set.  Thoughts on why and how to fix this?  Again, thanks for your help.

I had this same issue! Search through my post history. I fixed it by deleting the FSUIPC ini file and making a new one. Or maybe I reinstalled FSUIPC, I can't remember.
