Very nice ! Can't give you any advice on building planes b c you're better than me @ that. However, if I can advise you to wear a mask when sanding and glassing, you'd live longer and would make even more gorgeous planes yet. ;)
With a minimal investment in materials, I've made a couple vacuum molds recently and the results were less than stellar on the first attempt. I learned from my mistakes and the second attempt the parts were SO good. I was amazed. Fiber glass, resin and foam is cheap comparatively. I feel your pain on his prices.
