One of the guys over on ARC just completed a spectactular AH-64A in 32nd and I was able to use some of his techniques on the 48th Longbow I've got building. For the TADS and PNVS windows, (the FLIR windows, not the day side assembly) he used sections of a cut up CD. I whipped out my Dremel and started shaping the windows and it works REALLY well. Of course, getting one as small and curved as necessary for the PNVS window was a challenge, but it looks GREAT!
