|Here are pictures of Jim's new wings. The ribs are made
of aluminum honeycomb. The skin is bonded to the ribs without rivets.
The result is this absolutely stunning wing.

[...] We have completed our test for the new wing. The results were
fantastic. We first tested a section of the wing over one rib and
went to 14 g's with no failure. We then tested the wing for leaks
by putting air pressure in the tank area and it held the pressure
We then increased the air pressure to 20 psi. The skin looked
like a quilted pillow and finely failed when the skin wrinkled
at the ends by the rib and let the air out. The total load on
the 4 foot wing section was over 28,000 lbs. There was no failure
of the skin on any part of the ribs.
We took a new BD 4 wing to Sun 'N Fun and inclosing some photos.
The finished wing is very smooth and a lot easier to build then
We will be taking orders for complete wing kits with new wing
spars and without for those with the original spars. The ribs
come completely cut and wing skins have the leading edges formed.
The kits come with the adhesives, hardware, and all material needed.
We also will sell any parts separately.
