and
yet, at cruise I am trimmed several dots down from neutral, which would mean
considerable elevator deflection.
I'm
wondering if any IVP out there has the hstab incidence set up so that the
elevator is neutral at cruise? Colyn
Case
Colyn, the IV-P horizontal build specification is -.6 deg.
The general consensus is zero to -.2 deg is better. I put mine in at -.2
deg. I can’t say what effect that had yet. Additional note…
the horizontal as per Lancair’s CAD model is suppose to be a symmetrical airfoil
however mine came out as an inverted wing and it was closed in Redmond.
The top surface is flatter than the bottom. I CNC machined templates from
the CAD models and the bottom surface matches the CAD model perfectly and the
top surface, as I mentioned, is flat in comparison. My intuition is a
horizontal at zero deg will be a little faster than one at -.6 deg.
