For the 2009 PSS Fest I made a 60" Macchi Folgore. It was my first scratch built glass ship, and I was VERY happy with how it flew! I put together a set of graphics to be printed on decal paper, since they are not available commercially. These can be printed on regular waterslide decal paper, and look great once it's on the plane.
8.5"x11" decal paper can be purchased from

There are two PDF files, one for the left and right side of the plane. You can use either clear or white decal paper. I recommend using clear for the roundels, and white for the insignias. You can see these on the pics below.
Here's a video of my plane in flight.
