I am in the process of installing
the Horizontal Stabilizer. I have used a water level to level the Fuselage,
using the leveling marks molded into the
structure.
When I place the HS in the
preinstalled fixture for the HS, I find that I have almost a -1.4 degrees nose
down. When I adjust the HS to reflect the -0.6 degrees, the leading edge of
the HS is about 3/16 above the fixture. My kit, 386, is a fast build kit, so
the fixture was installed at the factory. Is it possible that the fixture was
installed slightly off the manual
specification???
I have reviewed the builder’s
manual and it calls for -0.6 degrees, nose down incidence. I have noted in
some in-flight pictures that in many cases the elevator is slightly down,
which in my mind means either the aircraft is at an aft CG or the HS has too
much nose down incidence. Has anyone noted either of these
problems???
Would it be prudent to decrease
the nose down incidence, and if so, how much???
