Ohhh, the calendar idea sounds really good to me too. The "doubles" would probably appeal to a broader group of people, but what about one focused a specific theater? Say the ETO, PTO, or Ostfront for example.
Not to derail this thread, but a couple of 1a/U4's were built toward the end of the War, and one was even captured by Watson's Whizzers, but didn't survive the flight to France, crashing in Jersey. In theory, one hit from the 50mm shell was sufficient to bring down a heavy bomber, even a B-17.
Beautiful work, Clave! I went to the site above and checked out your work. I love the Bulgarian Avia B.135. I'm a bit of a computer artist myself, nothing in your league, but I stick to 3-D work, especially Science-Fiction. The great thing about sci-fi work is nobody can tell you that your swastika is 2cm too far to the right, or some other such nonsense. I'm sure you're aware what great sticklers we airplane aficionados are about accuracy. At any rate keep up the great work (how about some IL-2's?).
