Some background info:
Focke-Wulf project VII Flitzer. The Flitzer was a study for a single-seat, jet powered fighter with performance superior to that of the Me 262.
Among all the speculative German aircraft designs, Focke-Wulf Flitzer should take prime space because it progressed beyond the "paper" stage, full-size mock-up and elements of the prototype aircraft being ready at the time of German surrender.
The design featured a twin-boom short-fuselage configuration used (independently) also on the deHavilland Vampire. A novel feature was the intended use of mixed jet and rocket power, later dropped in favour of a single Heinkel He S 011A turbojet. The intended armament included two 30mm in the lower nose plus two 20mm cannon in the wings.
