Would anyone be interested in purchasing a Vetter challenge style fairing?

I would be very interested, but like with you, price is a major consideration. There is more than one way to skin a cat. Vetter has his ideas, Fred Hayes has his, and you have yours. While all have proven to work, yours was done on a shoestring. Don't let the naysayers deter you-it's your dream and what you accomplished so far is mighty impressive! Personally, I think the tail section Alan and Craig run is much longer than it needs to be, but it depends on the design of the front. Different strokes for different folks!
There are a few injection mold/plastics outfits not too far from you. That might possibly be a viable alternative to fiberglass if and when you get plugs you like.
