Aviatik (Berg) 30.40

The Aviatik Berg 30.40 was a direct derivative from the Berg 30.27 powered by a 160hp Steyr Le-Rhône 11-cylinder rotary engine. Only one prototype was built and flown during summer 1918.

It was made out of wood except for the forward fuselage that was covered in light metal panels. The rest of the fuselage was ply covered. The wing had had fabric skinning and steel-tube bracings struts were used.
