The bastard child of a N-1 and an early Proton, with the same engines as the 2014-Antares-big-kaboom-rocket.

What could possibly go wrong ?  ::)  ;D
...you have been found guilty by the elders of the forum of a (imaginary) vendetta against Saint Elon - BLAAASPHEMER !

Thank you very much for the Pictures,  Dmitry_V_home

Its Quite Ironic,
That Chelomei who hated and scorn the N1 rocket.
and praised his Universal Rocket Design

Went and proposed Design with Kerolox and using Nk-33 engines...   

Interesting is fuel transfer between the Booster and Core

Is that a mistake of something? The core stage of the model seems to be upside down. The blue LOX tank is below the fuel tank. The common bulkhead is reversed. That is different from the diagram below.

Yes! One of several variants cross-feed.

Those engines, the NK33, were on the cusp of being 4 decades old when the accident happened. Maybe that had something to do with it, hmm?

Those engines, the NK-33 have been used successfully 4 times on the Soyuz-2-1vp.
