Yippie Kai Yay, Mr. Falcon.
This article from the Russian magazine Polygon about a little-known 1935 autogyro prototype was shared by Secret Projects forum member Hardrada55:
It was a TsAGI prototype for a fighter autogyro built in 1936, armed with one ShKAS 7.62 machinegun. Intended top speed was 245 km/h and a ceiling of 7,500m (24,600 ft), and powered by a Wright Cyclone F-3 engine, but apparently it crashed in 1937 because of a damaged blade, killing the test pilot.
Osoaviakhin Kaskr-2 was a 4 bladed gyro from 1930.
KASKR-2, remember the capitals in the designation.
There's also a page on it at Stingray's site.
Anyone ever see this russian bird before? I've seen the "black shark" and a Turkish version of this coaxial, but this Ka 58 is new to me.

Two more images of the Ka-58. However, I'm not sure whether it is a hypothetical design or the actual model.
Trust me, it's pure fiction. We already have a thread on it:
From Walter, the Demidov Gorniak-4:
The Gorniak 4 was a small original homebuilt design helicopter of Mr. Nikolai Demidov. The aircraft was first reported around 1985/1986. Possibly it was never built and remained a project only. The aircraft was powered by one 75hp (modified) Lada car engine.
From Walter, the Demchyenko-Khitry-Gusyev "Tourist":
The Tourist was an original design light homebuilt helicopter of Messrs. Demchyenko, Kittery and Gusyev. The ultra light aircraft was foldable and featured co-axial rotors and development period of some 9 years. It was reportedly completed around 1970 and was claimed to be suitable for transport in a suitcase sized container.
No picture, sorry.
Hello Stingray! I searched your site and I did not find a page to the Moscow Aviation Insititution autogyro MAI-205. Do you not have it? Here you can find info about it: http://www.aviastar.org/helicopters_eng/mai-205.php
Thanks! Just added it.
found this, its a model of a russian Uav concept called the Ka-153.
Keep Low. Move Fast. First Kill. Die LastOne Shot. One Kill. No Luck. Pure Skill.
There is no "Ka-153", and it is NOT a product of Kamov. What you just found is a model for the KumAPP/KB Polyot Korshun (Kite) UAV.
I traced the file name to a forum topic...
And it appears he confused it with the UAV project below, which is the Kamov Ka-135 (which he obviously misstyped as well).
As much as I admire your research work, 555, we can't assume that was his source. That file appears in a couple of other forums as well.
I reposted the Ka-135 in the Kamov thread. And wake up call to Stingray, it's not in your list yet!!
