Also, I would hope most US Submarines after the Holland would be small enough to make in FD, not that you couldn't. Alvama did a Mk IX iirc.
I was writing Alvama the other day, he's actually been interested in redoing his FD Type IX, unfortunately he's got other priorities and projects right now.
My next FD Sub, the USN "A" Class. These followed the Holland. After that, I'll progress up the alphabet for a while. On the works is also a German Type 7. Been going through my U-Boot books and forgot just how much I've got on them. I built several 1/32nd scale RC models for customers of a manufacturer back in 1994-5. Ended up with way touch reference material.
I'm looking forward to seeing what you guys create!
