BTW, all you need to measure are the RootChord, TipChord and halfspan of the wing and horizontal tail. Then the sweep of each and the distance from LE of the wing to LE of the horizontal stab. Then plug in 15% for the static margin and hit "refresh" or somesuch.

Easy to do. And it's given better "advice" than was printed in a couple of my recent ARF's manuals.
