I’m finishing up a Nos gas ship that has a sheeted leading edge. I was planning to cover the sheeted part with fiberglass/resin to give it some extra strength. However I planned to cover the wing with Nitrate/Polyspan. Will the nitrate go over the epoxy? I have stuff called Z-poxy, E-Z Lam and Klasscote. I have my doubts about this but though I’d ask.
Already tryed the fence thing with a Satellite which gave me a pile of nice Satellite bits which in turn were promptly eaten buy cows on the other side! The ship in question is a Eureka, I sheeted the LE with 4lb. balsa which is a bit soft and thought the glass would lend some dent resistance…you know fingernails, shop rash ect.
As far as I know it’s legal. Jeezz I hope so! I think the version that’s illegal is the later one with a flat bottom wing. Mine has the undercamber airfoil. I got the plans from NFFS and there’s some hand written notes telling you to sheet the wing to the second spar.
If anyone knows otherwise please let me know! I have a few other ships to build before the Nats. So many great designs, so little time…
Well, the Zaic book has a note to the effect “Suggest sheet LE as the glide is sometimes at fault with high rate of sink. Believed to be caused by laminar/turbulent breakaway at 1st spar caused by drop in speed when motor cuts”
Not shewn on the Zaic plan, maybe someone can advise if it was deemed a NOS-legal modification?
