My father is building a Bismarck from the Hachette partwork. So far it's going really well. Construction is time consuming but that's not the point. If you want a quick model, buy something RTR.
The detail is amazing and I particularly liked this little bit of ingenuity. The lower etch bends up at the sides and the main part folds around on itself. The result is a representation of one of the machine guns on the side of bridge. Once you get your head around the fold, it is very simple.
The starting point is only 20mm long. The boat is best part of five feet so there are a lot more bits to build and fit !
