Yes I've heard that lay-up schedule before. I like the term "Black Metal Engineering" very cool!. Some parts such as struts, beams and rigging I'll allow conservative thinking. The hull skins and all seem to be right on perhaps he was shy on working rigging or knows I'm going to pound it.

I could see playing with that for a serious disposable racer based on an annual basis. Once I have molds built and things going I'd like to play some with some really light weight hulls ect....

What are some of the other rules of thumb for Black Metal? Another I always hear it to always paint it. I've seen carbon break down from the sun.
