That's wonderful, both RC and the accuracy! What I've found personally, and it may not apply to others, is that the research is not only interesting, but it adds so much, not just to the model, but to the HISTORY! It;s fun and interesting to learn more about something. We would all love to see Pictures!
I picked U 557 because I had read the book, and that was the author's first boat, but also, it was such a typical boat! It lasted a year with less than moderate success. My USN Gato is a parallel. An early boat, that lasted a long time and had later fame by default, but it was built a year lager than 557, took almost exactly as long, and had almost exactly a a similar history. 2 things make it special...it lasted a long, long time and became the oldest (or nearly so) Gato still operating, and my 2nd Dad was a young Lt aboard her in 1957. But really, the backbone of the whole affair. Memphis Belle was a great air ship, but there were so may that didn't last one mission, or had average results.
Keep us posted!
