Hot from the mould: a port wing!
#1 a surprise success after infusion mishaps! It has many flaws but is actually usable! Weight is 561 grams. Potentially only 250 grams with these materials and methods. So there’s scope for improvement by using far less resin: The skin is already extremely thin, enough to meet the 250 gram target.
The bad news: There is no mould yet for a starboard wing. And the port mould took a year to make! Who can afford CNC machining?
