Based on the Mil V-12 Homer

[McColm]

The Mil V-12  Homer is the largest helicopter to have flown so far.
Kamov had two design developments known as the Ka-34 and Ka-35. Not to be confused with the modern helicopters with the same designation.
Amodel has released a 1/72 Mil V-12 Homer which sells at around $300 making it a bit pricey for me, which is why I have chosen to use the Revell 1/72 Airbus A400M Grizzly. Looks as though I have bought two of these but I have used some parts for other builds on one.
Raiding the spares box should throw up the necessary parts for the build. Two rotor stacks sit on the wings with a pair of engines from a B-52 under each wing.

Go one step beyond and make a tri-rotor like the Cierva Air Horse.

I might just do that

A Rotodyne fuselage might do for the Cierva one.

Got the Revell Rotodyne in the stash and I also found a fuselage of a Chinook
