Jim, I don't suppose you got a picture or two of the installation behind the
seat?

Barnaby Wainfan had a good article on gear fairings in May's Kitplanes.
According to him, a faired gear (leg and wheel) has less than 20% of the
drag of an unfaired gear. The faired gear leg contributes the major portion
while the pant only reduces the drag by about 8% in his example.

Yes, I saw Wainfan's Kitplanes article but assumed that he was describing a
generalized case that may not fit the Tailwind gear design per se. I was
hoping some one (or several) Tailwinders had made some accurate speed measurements
in the "before" versus "after" condition. The most useful info would be in
terms of actual speed change rather than in percent of drag change. Anyone out
there with such data?

I came accross this link in the RV forum
http://www.rv-8.com/Cowl.htm. It highlights the
challenges in mounting a Sam James fiberglass cowl on
a RV-8. This builder spent months on finishing the
cowl to paint specs. The biggest complaint was pin
holes and surface problems to repair. I hope most of
these issues have been addressed by using polyester
gel coat, carbon fiber and Coremat to reinforce the
cowl. The bottom mold for the W-10 is now complete and
will yeild it's first part early next week. I'll post
pictures as soon as possible.
