Mark Here is what I did.
what do I use for a thrust datum line when setting the wings and HS? The longeron line between the front and rear spars is what I used as a reference point. I believe others use the same. Though the angle appears otherwise, the spirit level in this photo http://www.kr-2s.com/images/yellow_600.jpg is leveling the reference point.before setting the HS incidence angle. > I am also seeing a "V" support configuration on the braces between the > upper > longerons on a lot of the sites...

In the above photo and this one http://www.kr-2s.com/images/diagonal_600.jpg you can see the 2 "v" braces called for in the plans. Hope this helps.
