First I planned to cut out the side elevation from 8 mm plywood, to fix the motors and the battery and cover it with foam parts. This was massive, but too heavy.
Then I cutted the whole fuselage from Styrodur:
I had some problems to fix the rear motor and the shaft, so I decided to build a simple balsabox as fuselage and cover it with the foan parts. That`s it for the moment.
I wanted to use two Speed 400 with Gnther props for the prototype, but I`ll use geared 400, because the efficiency is much better for that speed.
battery 7 / 1800
2 x Speed 400
During this periode I tried the different versions, described above.
In 1945 a high altitude observer version Do 335 B-4 was planed. Wingspan 18,40 m. This leads to a model wingspan of 153,33 cm (scale 1:12), using the original fuselage. The wing was also cutted from Styrodur.

I tested two different types of fuselages:
I think the foam one is the most stable and easiest.
