you and your titanics.... how much is? What a materials are you using? Remote Controlled?
By "how much is", I'm assuming you mean "how much is it?" There is no set price, I just buy the materials  I need when I need them. I'm using all different sorts of wood (Maple, birch, pine, balsa), styrene, sprue (the "trees" left over from model kits), metal wire, fishing line (rigging), and I'm buying a few parts here and there that would be too complex to me to replicate 30 or so of them. This ship will be static display because water would slowly damage the hull...  not to mention, I would not want it to flip.
