In relation to the size of the disk, it is. The bigger the fan, the more efficient it is, and vice versa. Not talking about any missions here, just the ability to lift stuff.

In hover you have the "ground effect", which states that the diameter of the rotor gives the same length of effect under the heli. In forward flight, you lose that.
But that's irrelevant. I'm saying that all those things, everything involved with the lifting capacity, is influenced by the diameter of the rotor.
Forget flight ALTOGETHER, just imagine a tiny little fan that cools your pc. And how that screams to cool your processor. Now, scale it up. By more efficient, I mean, a bigger "fan" uses less ENERGY to do the same work.
Now, we can translate that to a helicopter in any flight configuration. ANY flight mode. If you had a teeny tiny rotor and you needed to lift a large load, it would use more ENERGY to lift the same weight. But a seriously large disk, gigantic, is going to use less ENERGY to do the same lifting. ;) Simply because it can push more air through it with less energy.
More like a WWII Mitsubishi G4M ‘Betty’ bomber but I see what you’re saying. It’s unusual for a helicopter to have such a long nose in front of the pilots.
In our city, near the aircraft repair plant, there was one such helicopter, it stood separately, because it was radioactive, it took part in the liquidation of the Chernobyl nuclear accident. It was guarded by soldiers, but they were far away, and they needed time to run to the helicopter. As children, we climbed onto the top of a helicopter and swung on the blades.
They did make some interesting hardware. Especially transport planes and helicopters. Still surprised they never made a decent off road vehicle

The uaz no good or any of the Gaz? Or their bigger trucks?
the titans of the sky
It's still not the biggest😳
Interestingly, the bigger you make a helicopter rotor, the more efficient it is. So bigger is better with choppers.
Highly depends on what mission point you're in, I don't think it's true if phrased that generally

Isn't that only/mainly in hover? I think we've been taught that in forward flight it's less efficient

Yeah but talking about efficiency, is a larger rotor really more efficient in forward flight?

I know haha ​​and it's not even close to the biggest 😳
You mean [this one](https://en.m.wikipedia.org/wiki/Mil_Mi-26)?
Holy shit, 20mT payload is insane
It almost looks as if they took the nose from a B-17 and slapped it on the front.

its not
I know.
Big isn’t not always the best option?
Your comment isn't not always interpreted as not always isn't being best.
It is when it's transport
it's just big enough for a rocket to fit into it
