I am using wet layup and I am not looking forward to use resin inf, because in vaccum as for me it is easier to get better results I want the wing to be the same profile along whole part so I found some decent-looking wing profile from the internet and I want to transfer it to reality . After couple restless nights I have some ideas and I want to share them with you Guys and according to your tips I would like to choose the best option Idea #1 : Build a skeleton with ribs cuted to the wing profile as it is made with conventional aircraft wings and then then cover(skin) it with single layer of 220gsm cf (laminated on piece of glass) by gluing flat layer of carbon to every rib. This picture maybye will make it easier to understand due to my pathetic english. http://www.kartonowki.pl/storage/publisher/images/R2798/picture_30b2301fe4fbfda3670f9588068a2d3c.jpg Idea #2 : I was thinking about producing 1:1 scale foam core and then wrap/skin it with couple layers to make it stronger and finnally to make it nice-looking Idea #3 : I think that third idea is the hardest, but maybe the best for future comercial use. I was thinking about producing plug from foam, wood, mdf etc. and the make a split mould for that, but how to split a mould for wing I have 2 ideas as shown on this picture, red line means place where mould would split http://tiny.pl/q7dw8. The hardest part of the mould is the leading edge. As for now I can't really choose any idea, because every has its advantages and disadvantages ( Please help, share your idea if have any, comment my ideas it would really help Thank you for taking your time reading my post. Bye! Wojtek from Poland ~~~Everytime I hear sound of demoulding part I have eargasm~~~

Cut the flaom with a hot wire, skin the core and then put it back into the foam block so it doesn't warp. Works well for a one off. Method 3 would be my choice (and in fact how I made my wing) if you want to make multiple mouldings. I made mine fairly thick to get round the need for ribs and spars but it does make for a heavier finished item. Make the mouldings then clamp the moulds together and bond with some carbon tape. Works really well for me.
