Answer to Squirrelly Dan About the S-wing

[eschrom]

The site wouldn't allow me to reply directly to SD's post, maybe because of the forum in which it was posted (?).

The S-wing has 11 ribs, the original only nine. There is some strengthening of the spar also but the rib count should give it away.

If you look through the lightening holes behind the main spar you should see an aluminum angle riveted along the top. It measures 1.25X 1.25X 1/8. If it isn't there, it doesn't have the mod. The picture may help.
