    1. Assuming the windows are to size, yes, this would be much smaller than the V-12 or even the Mi-26. It does seem to be the same size of the e.g. the V-22, so I wouldnt call it small.

    2. While this specific version is smaller, its possible that it is derived from a larger project.

    3. The russian sources talking about the project that I am refering to said that it would have twice the payload capacity of the Mi-26. That means that you are either talking about a different project or are wrong about this point.

    I think the advancement of computer simulation and wind tunnel research can not eliminate a X-plane. Eventually one has to build a plane and send it to the sky to prove its worthiness if the simulation and wind tunnel model show some promises. The difference compared to the 60s and 70s is that this time, one can put a sophisticated robotic pilot (control device) in the cockpit than risking the life of a human. To me, X-plane is a special-purposed tech demonstrators.

    Thank you. The weight of the main gear box of helicopter grows more than proportional to the power transmitted and both Mi-6 and Mi-26 when they appeared had main gear boxes much more powerful than any other country could build. I suppose that 3D printing a gear box housing from Titanium might achieve an acceptable weight at a much higher power than used by Mi-26.

    The configuration is based on the Transverse rotor design.
    The V12 of Mil used this configuration and in essence the rotor drives and engines of 2 Mi 8 hop helicopters. Like the V22 or the Bell V280 concept The engines appear to be mounted at the wing tops. Likely 1 per wing housed in the nacelle with transmsions in three directions. The main to the rotor a second to pusher prop and a Third to allow auxiliary power to the other nacelle in the case of engine failure.

    That's the Shadow 8.

    Time to try forward propeller / upper rotor with larger diameter and lower number of blades than aft propeller / lower rotor to reduce the cutting of tip vortices by aft propeller / lower rotor blades. See the propellers of the An-70 where the aft propeller has fewer propeller blades no doubt because of otherwise running into trans sonic trouble.
