Need more room in your hull? The Dusseldorf fire boat RC model is based on the original build and design of the boat. In 1979 the hull was extended. So, if you modify the model by the same amount as the real boat you would gain 8 inches (200mm) in the middle. (The superstructure was not changed although there are some other major modifications.)
This is what I am doing to mine which I got in January 2022. It was given to me as the previous owner probably got in too deep (above his head) with all the channels and trying to use an 8 channel Spektrum RC system.
I completely unassembled everything (fortunately he had not cemented the main deck in place) and pulled all of the wiring out. It was kind of a mess, something one would not expect with such a great model kit.
I know of at least one other person that has lengthened his boat with all of the gear inside it.
