|
|
You, like I, may have heard or read that Kitfox I-III and Avid HH use the same airfoil and wing ribs, therefore, are exact duplicates of each other. Thanks to a local KF-II builder, I had the opportunity to do a hands-on comparison of both ribs. Pics show results.
Note: in photos, KF-II rib is a new replacement which matched original perfectly; Avid HH rib has blue tape on capstrip.
