I'm looking for an article from a magazine called " Planes." It was published by AERODATA in the 80's. The particular article that I'm looking for is the A.W. Whitley, Part 1. It is in issue #11, 1984. Any assisttance will be appreciated.
I use the mylar from a package of chewing gum my wife bought at the grocerystore. It was a large package with 6 smaller packs inside. When cut open, I have a sheet of foil-backed mylar about 6inches by 10 inches.
