KR> What can I use as a thrust line datum on a slightly modified KR2 project
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.

KR> What can I use as a thrust line datum on a slightly modified KR2 project
I bought a partially completed project about a year ago (boat stage with spars) and finally got my work bench put together. The ID on the fuse is at about 35" and when I put it on my bench, there is about a 1/2" 'lift' to the longeron when the fuse is upside down on the bench. I am assuming that is normal for a 'boat' that is wider than plans, so I am okay with that, but how or what do I use for a thrust datum line when setting the wings and HS? I am also seeing a "V" support configuration on the braces between the upper longerons on a lot of the sites... I am not seeing (or I am missing) this configuration in the plans. Does this improve the rigidity of the fuse and make the airframe a little more robust in stress conditions? Thanks for your help. Mark W N952MW
