Rich, I lost your post when I went looking for the forum. Anyway here's the address I have for it:
forums.x-plane.org/lofiversion/index.php?t18748.html
I hope that's enough to get you there. I went back to Google and typed in 'Bell X-1A' and this was on the 4th page of results.
BTW, the drawing in "Replica" is a different drawing. I had to cut and paste your url into Firefox because Netscape wasn't getting through. I think I'll be back there to browse some more.
