Thanks to all you knowledgable folks for educating me a little on this. Just talked recently to Ken Cottle who put these BID wings of mine together back in 1987. My KR-1? was signed off for flight April 21, 1987. This is the plane used in the VHS video on how to install the Diehl wingskins. Both Dan and Ken looked pretty young back then. Funny how the people who built this plane don't look the same anymore even though the plane they built still does. Building an airplane is a way to make a small claim on immortality. I recently ferried an SA102 Cavalier from San Diego to Shelbyville, Indiana where the new owner is making it look like new again. The fellow who built it in 1974 died two years later but his plane lives on all these years later. When you builders put your nameplates on the fuselage under the tail, you have created something that will likely be around for a long time after you're gone. I doubt anybody thinks about that when they've finished building a plane, but somebody someday, looking at that nameplate, will wonder who you were. Affordable Wireless Plans Set up is easy.

Mike, BID is a short-hand call-out for Bi-directional fiber glass cloth; approximately the same number of fiber strands crossing each other at 90 degrees in the woven cloth. (Lots of weave patterns for fiber glass cloth on the market: plain weave, Crow Foot, Satin weave, etc. The Aircraft Spruce catalog has a good reference for the home builder.) The BID will have approximately the same strength and stiffness in 90 degree directions. Most plans call for the BID to be applied at 45-degrees fabric orientation to the main spar to enhance torsional strength of the wing. The Diehl wing skins use this same 45-degree fabric orientation when they are constructed at the factory. Sid Wood Tri-gear KR-2 N6242 Mechanicsville, MD, USA > "The Diehl wing skins are a sandwich with inner and outer layers of 2 BID on a foam core. I have talked with other builders that have used the Diehl skins and not used the spar extensions; they just use the rather stiff skin as a monocoque stressed skin. The Diehl skins extend the horizontal stabilizer and elevator span 3-inches each side for an increase of 6 inches more than the KR-2 plans." Thanks for posting that info on the Diehl tailfeathers & skins. I never knew the stabilizer had three inches extra. Nor do I know what BID is . . . but I can Google fu and find out. Whatever it is it sure holds up well. They literally still look like new after thirty years, tops and bottoms. Whatever BID is, it's good stuff. Mike KSEE

Yep, that is what I used in my first Kr-2 BID 35 years ago.
