I continue to read, on this site and others, of the vertical stabilizer stitching failing . Various fixes have been tried with little apparent success. What causes the stitches to fail and, does anyone have the solution or a good idea for a fix. I see "Cubs" with no stitches, with two stitches and at least one that had both ribs stitched at about 2 1/2"; lots of stitches. Jared removed the cover on "Barn Cub"; I haven't looked at it but we still have it; not sure of the stitching there but we do want to replicate whatever it was. Piper drawings show two stitches on the upper rib only. Ideas, thoughts or opinions? Thanks.....
