Understand RV-7, 8 and 9 have the same Vert Stabilizer. Is there anything in the "Newer Instructions" about about tapering (angling) the flanges of the VS Ribs to match the desired contour (taper) of the VS ??? Thanks, Garey ________________________________ Message 2 _____________________________________ Time: 03:11:20 PM PST US From: Marvin Dorris Jr Subject: RE: RV7-List: FLUTING Ribs to match desired taper of VS I think the only thing you should be doing to the flanges is making sure th ey are 90 degrees to the rib AND fluting them to make sure the ribs, laying flat, are parallel to the flat surface (no humps or "ski jumps", etc). No t sure what you mean by angling to match the contour of the VS. The VS sho uld take the contour of the rib. Maybe I'm missing something.

When building mine, I determined that from the spar rearward, I would be good to go bending the flange at 90 degrees. From the spar forward, I used a flashlight shining through the skin onto the rib to see if I needed to open the bend slightly. If you see light between the rib and skin, open the bend at that point. Not much bend is needed, but I found a little helped a lot.
