T-3
SEVERAL years ago, I began experimenting with the use of foam-core board in aircraft modeling. At first, I substituted foam-core board for balsa in bulkheads, formers, and ribs. After observing the characteristics of the material in these applications, I decided to build an entire model primarily of foam-core board. The first fuselage was constructed in the traditional manner, using slab sides. The only difference was that I used foam-core board instead of balsa. The method worked, but it was difficult to hide the exposed edges; finally, spackling compound was used as a filler, which resulted in a fairly satisfactory finish.
