I just installed mine a couple weeks ago at 0 degrees based on recommendation from a “professional builder.

 

 

 

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???
