2walla,
Normally the shear web orientation is vertical. Do you mean that some shear webs were put in with the balsa grain runnung horizontal? I have a Hanger 9 RV-8 that has most of the shear webs in the wing where the ends of the shear webs don't completely go to the sides of the ribs. I fly that one competely in a scale like fashion. I would expect better from Hanger 9, especially since the Katana was designed by Mike McConnell, Hanger 9"s pro designer. I'm starting to understand why the Katana was discontinued.
