Once all that is done prepare the epoxy resin (I used around 100gr in total of epoxy and hardener). Using a soft roller, first apply some to the ebechi. Then put the carbon fabric onto it and roll to “pull up” the epoxy. Add more epoxy resin as necessary. You can use a hard roller and some kitchen paper to remove excess epoxy (I “removed” around 6gr on the entire wing – very minimal).<\/p>\n
Assemble all the bits of the wing into the negative, making sure the wing cores are in the right position, cover with the negative “covers”, making sure you fix key bits with a bit of painters tape.<\/p>\n
Then put the whole building board into the vacuum bag. Start the vacuum pump and leave it running for 10-12 hours at -150mbar. I use a webcam and a timer so that I can check the pressure from time to time (although my vacuum pump has no trouble keeping this up).<\/p>\n
This afternoon I put the first wing of the Elfe S3 into vacuum. We always build the wings “upside down”, starting with the upper side first. Before being able to do so it does take a bit of preparation: Of course you need the wing cores cut from foam (which we already did back in […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_post_was_ever_published":false},"categories":[15,26,1],"tags":[],"class_list":["post-3613","post","type-post","status-publish","format-standard","hentry","category-techniques","category-neukom-elfe-s3","category-uncategorized"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/p9zI6K-Wh","jetpack_likes_enabled":true,"jetpack-related-posts":[],"_links":{"self":[{"href":"https:\/\/www.lefevere.eu\/modellflug\/wp-json\/wp\/v2\/posts\/3613","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.lefevere.eu\/modellflug\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.lefevere.eu\/modellflug\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.lefevere.eu\/modellflug\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.lefevere.eu\/modellflug\/wp-json\/wp\/v2\/comments?post=3613"}],"version-history":[{"count":1,"href":"https:\/\/www.lefevere.eu\/modellflug\/wp-json\/wp\/v2\/posts\/3613\/revisions"}],"predecessor-version":[{"id":3620,"href":"https:\/\/www.lefevere.eu\/modellflug\/wp-json\/wp\/v2\/posts\/3613\/revisions\/3620"}],"wp:attachment":[{"href":"https:\/\/www.lefevere.eu\/modellflug\/wp-json\/wp\/v2\/media?parent=3613"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.lefevere.eu\/modellflug\/wp-json\/wp\/v2\/categories?post=3613"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.lefevere.eu\/modellflug\/wp-json\/wp\/v2\/tags?post=3613"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"\"](\"https:\/\/i0.wp.com\/www.lefevere.eu\/modellflug\/wp-content\/uploads\/2026\/02\/IMG_4659.jpg?resize=510%2C680&ssl=1\")
