It has been 15 yrs or better but at 1 of the gatherings Jeanett told a group of use that she had an enginer do a load test of the wing and the carry thru spare gave out before the attach fittings. She was woried about folks adding wing extensions. It was around 92 or 93 Maybe even earler.

With only one layer of glass from the forward spar to the trail edge, and assuming probably the same amount of resin, I don't see where the extra cost of carbon fiber could be justified financially for the weight savings of the cloth alone which, in all probability, will be about the same. The weight savings generally comes in using less layers of cloth, which in this case. you can't do. The weakest part of the wing is at the attach fittings. Using carbon fiber won't change that. The chain is only as strong as it's weakest link and you're not improving the weak link. Carbon fiber is probably 4 times more expensive. The difference would probably buy a nice hand held radio. :-) Just a thought from the far side...........
