Hi stevel I'm afraid you'll have to be a bit more specific. Wings come in various sizes, shapes and more importantly various mounting systems. Are you working on a DIY foil or assembling one from various spare parts or replacing existing wings on a brand name foil... ?
One of the WA guys made me a set of carbon wings for my LF Fish - I never got them set up right and eventually sold them. He may have the molds still.
From memory they sold for maybe $500 for the set ? There is a huge number of hours involved, not to mention the materials cost. It wouldn't be a cheap option, seeing that other post about $500 complete foils now available from china.
pm me if you want me to put you in touch with him.
