I think the same technique would still work, but they can also be made easily in 2dit would be really helpful if someone also comes up with good reliable tutorial on how to CAD model Flitetest foldable under-cambered swept-back foamboard wings,apart from Master series foamboard wings considering the bend radius, foamboard thickness where we can't use sweep command as it scales down the airfoil geometry at the wing tips, which is not the real scenario in foldable Flitetest swept-back foamboard wings.
