Thank you for buying an aero-naut kit!
Kalle 2 is the model of a small steam tug which was in use in the 20ies and 30ies of the last century.
This kit contains precisely laser-cut parts and a sheet of photo-etched brass parts for the fine details
which give the model its realistic appearance.
Before you start building, please read the instruction manual carefully and completely for a better
understanding of the design of this model. Pre-treatment of parts and assemblies and the application
of paint should be planned ahead of the building process. Depending on your favourite colour
scheme it may be necessary to change the building sequence given in the instruction manual and to
paint individual assemblies before installation.
Construction should be according to the step-by-step instructions provided in the manual. Use a
sharp modeller´s knife to cut the tabs of the laser-cut parts. Use fine sandpaper to remove any
residue of the laser-cutting process from parts, to sand off tabs, create good contact surfaces for
gluing and enhance the overall appearance of your model.
Before you glue, always check that parts fit perfectly and correct, if necessary. Give glue sufficient
time to dry or cure before you proceed to the next building step.
You can apply your favourite colour scheme to your model. Make sure to clean the polystyrene
hull thoroughly and to use a primer suitable for your paint job. Treat wood parts with sanding
sealer and filler before you apply paint to achieve a smooth surface.
