I noticed this on Monday this week, which is slowing me down a bit. 3D printing cost for the wheelhouse and the superstructure easily match the price of a complete model. To this end I wait for the model to become available and assess during the build the missing details or shortcomings for the model.
Further I started to decouple the parts of my S18 type boat and will offer undetailed parts in strong flexible (eg. kitchtenoof, superstructure and wheelhouse, Torpedotubes) while offering detailed parts set on the other hand. This should make the whole model more affordable and fun to build but it also takes some time for decoupling and designing the right mounts for the detailed parts.
But building such models newer be a sprint and the side shields and other parts can be reused for an S26 type boat user by my favorite 3rd Schneellbootflotille in the Mediterranean Sea.
