The UK WWII Aircraft PDF sets have been released. It is available in four different scales: 1/600, 1/1800, 1/2400, and 1/3000. There are 29 different aircraft represented from the UK WWII era. These come in digital pdf format in either US Letter paper size or European A4 paper size. The 1/600 scale is the original scale we used for our printed sets in the past. So if you purchased printed sets from us in the past the 1/600 scale option will match those aircraft. For more details click HERE.
