There was a German modeling site that had a variety of HSF ship plans in 1:100. I can not remember the name of it and my Google-fu is weak on this one. Does any one know what it is?
Mmmm... here? Click on Bauplane to get a drop-down menu of classes of ship to choose from. Some are in 1:125 scale, but not too bad to deal with.
Yes, I have great respect for the Dreadnought Project fella for scanning those plans in and posting them freely.
