im toying with the idea of scratching my laid up fiberglass over ply fins for some same size, but considerably lighter and thinner carbon fins...
several years ago i was asking an accomplished L3 about an all carbon design for a mach buster (actually mach shredder), and he told me that it's always a wise choice to go with fiberglass underneath the carbon fiber because it's more elastic and less prone to catastrophically shatter. given the propensity for the fins to flutter in, lets face it, my less than "perfect" designs, i'd like a real world, or pretty educated opinion on the issue.
just as an FYI. i realize i could make the carbon fins thicker, and that would in turn reduce the risk, however, this is about shaving both weight, and drag, while increasing strength, so i'd like to compromise as little as possible in those areas in the name of reaching maximum velocity.
