I have made a mould for the port wing (unsealed below), and it has held a vacuum gauge steady for 54 hours now: I think the seal is excellent. So far so good, but an awful lot of work remains to test convenience of a moulding cycle. And first, I need to reinforce to mould  to withstand the pressure when empty. I ran this test with the wing plug inside to support it against the air-pressure load.<\/p>\n\n\n\n<p>See the vacuum test at <a href=\"https:\/\/www.instagram.com\/p\/Crh2p7VMjc0\/\">https:\/\/www.instagram.com\/p\/Crh2p7VMjc0\/<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/agileaircraft.com\/wp-content\/uploads\/2023\/04\/WingMould_2313-1024x768.jpg\" alt=\"\" class=\"wp-image-400\" srcset=\"https:\/\/agileaircraft.com\/wp-content\/uploads\/2023\/04\/WingMould_2313-1024x768.jpg 1024w, https:\/\/agileaircraft.com\/wp-content\/uploads\/2023\/04\/WingMould_2313-300x225.jpg 300w, https:\/\/agileaircraft.com\/wp-content\/uploads\/2023\/04\/WingMould_2313-768x576.jpg 768w, https:\/\/agileaircraft.com\/wp-content\/uploads\/2023\/04\/WingMould_2313-1536x1152.jpg 1536w, https:\/\/agileaircraft.com\/wp-content\/uploads\/2023\/04\/WingMould_2313-2048x1536.jpg 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The test-wings are too expensive, and unnecessarily heavy, to be suitable for production.
