evelopment of the IS-2. Expected top speed with a 1215kW M-120 engine was expected of 720km/h ! Unfortunately, as often happens, the engine didn't materialize, therefore Nitikin substituted the 1400hp Mikulin AM-37.
The IS-4 was apparently flown sometime late 1940 or early 1941, but the flight records were lost in the German invasion.
Drawings (40k) provided by Dean McGinnes shows two different designs of IS-4. One above is an original outline (M-120 powered) and one below (AM-37 engine) was actually built and flown.
See also photos and drawings of rubber-powered IS-4 (penaut scale) at Dean McGinnes page, the only flying IS-4 at the moment;
Additionally, even though Nitikin created up as much as he could of the airframe and related equipment of his experimental design bureau, no trace of the airplane survived the hurried evacuation. As the press of events forced the Soviet aircraft industry to concentrate upon conventional designs which could be produced in greater numbers in a short period, and the fact that apparently the IS-4 had some rather unusual handling characteristics, further work was halted.
