The base is built first and is very stable thanks to the technical components. A rail is required for the fuselage, which was unfortunately missing. Of course you can also build the boat without it, but it will then constantly roll around. Since I have a 3D printer, I quickly printed a replacement. The interior is rather rudimentary and, thanks to the functions, consists largely of technical components. This means that side walls can be opened or extended later.

On one side, some panels are transparent and offer a view inside. The covers can also be opened and slid on without having to remove the parts. The front and rear are built last. While the stern can be opened, nothing can be opened at the bow.


The quality and stability are excellent. However, the price is quite high when you compare the set with other manufacturers. It is rather questionable whether many buyers can be found there. Especially since it is not a well-known type of boat.
