At first glance this heavy fighter/light bomber design study of the late 1930s appears conventional, however appearances can be deceptive. The twin engines were buried in the thickened wing root and the nacelles contain only the extension drive shaft and annular radiators. This has been one of the most difficult aircraft to model, the complex shape of the fuselage with the engine bulge has required many iterations to achieve with a reasonable amount of material. I suspect that had this aircraft been built it would have been expensive to manufacture and awkward to maintain.
