Subject: Legacy Horiz Stab Angle Of Incidence

The Legacy construction manual calls for -0.3 to -0.6 degrees angle of
incidence for the horizontal stabilizer.  Since there are a number of
Legacy's flying now, I thought I'd ask what has been used and how well it
has worked out.  

What I mean by how well has it worked out is, for example, if you're flying
a Legacy with an IO-550, with the c. g. in the middle of the c. g. envelope,
does your elevator ride perfectly in trail of the stabilizer?  If not about
how much is it off and in which direction?  The optimal angle of incidence
is going to be a function of engine selection and I'd expect the more
negative end of the range is best for the IO-550 vs. the lighter IO-360
engine option...

Thanks,
