Perhaps we could ask Lancair to give us the dimensions
relative to the firewall hard points instead of the
canopy rails.

Paul, I measured the longerons on the Legacy. They come out to 9.25" below
the top of the cowl or 1.125" below the top hardpoints.  The drawing shows
the thrust line to be 1.5" below the longeron line, then angles down 1
degree and to the right 2 degrees.

OK Bill that makes a lot more sense. I'll work on it some more.

BTW you are using the 2.85:1 gear box as that has the prop
rotating in the right direction?

Yes.  The RD1-C

OK the trick here is this side truss must lie in a single
plain. The length of the schertz beam is adjusted accordingly.
The lower outer firewall mounting points are not really
needed but we will use them anyway to laterally brace
the nose gear space frame. Not shown yet. There are
some othe minor braces as well. The rear motor mount will
required a custom oil pan but it too is rather simple.
Not done yet. I just want to know what all you people
think.
