I've got over 30 hours in the Frasca and have never had problems
setting the trim. In fact one of the instructors (I've taken the
courses at the local college) used to chide me for flying entire
practice sequences (45 minutes) with nothing but the trim for
everything other than the takeoff.

We've got 4 ATPs (is that the right company?) but I haven't
had a chance to use those yet. They're for the multi students.

I've got FS2002 and have never been able to get trim to work
properly.
