Rib stitching interval

[C5Engineer 1170]

I'm covering in Ceconite 102 with flat rib lacing. If you use the charts in the books you can barely get on them with my VNE of 95. I'm to the point or stitching on my wings and I was curious what spacing guys are using. I'm thinking 4" should be more than sufficient considering they were not even stitched before I uncovered them. I'd love to hear what others who stitched used.

I think I went with 4" on mine.  I have the aluminum leading edge so I started end of the leading edge skin and went back.  The closer you get to the trailing edge, you have to use the curved needle and do the bottom by itself.  As soon as you get the hang of it it goes real quick.  I will measure today when I get home.

4" seems to be the consensus

I lied.  I just measured and  I went 3.5" for some reason.  Not sure why, but I did.
