The latest Legacy manual calls for a -0.5 degree angle of incidence for the
horizontal stabilizer -- rather than anywhere in the -0.3 to -0.6 degrees
range in the earlier edition.  Couldn't chat with Carsten about this because
he is away helping the Mexican Navy get their new squadron of Lancairs
built.  Mark Mahnke says the new manual should say -0.5 +/- 0.2   -- but,
agrees that the best source today is how well it's working out for the
flying Legacys.  

He also said that the L-IV builders have been through this "optimization"
because most Fours were flying with the elevator down a bit.  He said
they've even built some Fours with the HS AOI shifted up to zero degrees and
that it didn't even change the elevator trim position...  Go figure...
