Thank you all for your nice comments, I am really glad you like my F.2B.
Here some pics showing how I built the fuselage. I simply downloaded the construction manual for WNW F.2B and copied as much as possible.

First of all I completed the sides of the fuselage (without the engine section) , then glued one side together with the bottom side. Doing so I got two sides in 90 degrees angle and could complete all parts of cockpit interior. Afterwards I glued the other side of the fuselage and consequently the top of the fuselage.
The engine section is made of full plastic due to the complicated shape - requires a lot of sanding, but I am quite satisfied with the result.
Hope these pics will help, in case of any questions just let me know, I will be happy to help.
