Hi all,
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.
Thanks!

Nitrate sticks to almost everything. It will go over the resin no problem. Why are you gonna glass the sheeting? it still won’t go through a fence. 😀
Hi Dan,
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.
Thanks for the info!

Dan – is the Mk2 Eureka, with sheeted leading edge, Nostalgia legal ??? I have (or had) a feeling not.. but stand to be corrected
Hi Jim,
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?
