As promised you'll find our answers regarding the points raised recently (2nd planking and portholes).
Regarding the 2nd planking, a few customers think it should not be necessary and could make the model out of scale. This 2nd planking is actually crucial for both the RC and static model of the Bismarck and it is very important to follow the step-by-step instructions. In both cases, the 2nd planking helps to re-inforce the structure, which is an imperative for the RC version. For the static model, the 2nd planking is also particularly useful for beginners as they will find it easier to get a neat finish, the 2nd planking being thinner and easier to apply.
If the modelers sand the 1st and then the 2 planking as per the instructions given in the magazine (from issue 11), all the pieces will fit perfectly as we will show in issue 43.
Concerning the portholes, Amati has chosen to make the building process in 2 stages. This is here again geared towards beginners to avoid any mistake. We first give identical wooden section with holes for both sides. We then give a paper template for the left and the right side and you will just have to fill some holes when necessary and drill some extra ones When done, the model will have the right number of portholes which are correctly positioned. The final steps are explained in issue 54.
We have put a lot of research in this model and we are confident that the finished model will meet your expectations.
