WebHowever, a high aspect ratio fin does not necessarily have to be very thick. Therefore, it will be made of carbon (depending on the thickness), so it will be a bit heavier than a foam wing. Low aspect and thin wings, on the other hand, require a lot of rigidity and will therefore be heavier because they are made of 100% carbon.
