"Let's see how insanely huge we can make them!"
Airplanes you can understand: they're basically just big birds, with
recognizable wings, tail and body. But helicopters... are somewhat
strange beasts. It's a wonder why anyone took Mr. Sikorsky (and his
predecessors) seriously, and an even bigger wonder how they got anyone
remotely sane enough to sit inside one of those early prototypes and hit
the START button. Also read Part 1 - "World's Biggest Airplanes"

Beyond the fact that helicopters came out of left field (the far, far
left field) the craziness continues when you begin to think about how
easy it is for something to seriously -- and traumatically -- go wrong
with one. An airplane, after all, can glide if its engines fail. An
airship (dirigible, zeppelin, etc) can usually descend if it loses too
much lift. But a whirlybird without power has one - and only one
(barring autorotation) -- option: crash.

But, thankfully, Mr. Sikorsky didn't give up and today we are lucky to
have the results of his work: incredibly flexible, wonderfully useful,
spectacularly nimble aircraft. Although many breeds of helicopter have
become quite safe, there is still a lingering kind of madness regarding
these "whirlybirds": the drive to see how insanely huge we can make
them.

Unlike airplanes, the size-wars with helicopters began after World War
II. While, like a lot of aircraft technology, helicopters were
jump-started into being useful and moderately reliable machines, the
early 40s aircraft were lucky enough to get into the air -- let alone
get into the air without killing the pilot.
But this clumsy infancy didn't last very long. The 1950s saw an
explosion of radical -- and in some cases terrifying -- helicopter
designs in both the United States as well as the Soviet Union. One of
the grander designs is one that is pretty familiar as it's been used by
both the US military as well as civilian companies in need of some heavy
lifting. Looking something like a twin-rotored banana, the earliest Boeing Chinook popped up in the late 50s but because of its heavy lifting skills, stayed around for a very long time.
"Helicopters are coming!" in Look Magazine, May 18, 1954, via
Modern, updated versions are still used all over the world. The
Chinook, in fact, is kind of the poster-child for big helicopters. Got
something heavy that needs to go from impossible point A to impossible
point B? More than likely the machine connecting the dots is a Chinook.
While numbers are rarely impressive, the size of the numbers the
modern Chinook can lift are still ones to give pause: 28,000 pounds of
cargo, which is about 14 tons...

The whole range of Soviet "monster" helicopters
Another Goliath is the MI-6,
made by the Soviet Mikhail Mil design bureau. Again created in the
50s, the MI-6 was a true monster. While not as oddly stylish as the
Chinook, this powerhouse could lift 26,000 pounds of cargo (12 tons),
being an incredibly versatile heavy hauler. Almost all of these types
of machines were very popular with the Soviets, spawning a whole range
of monster helicopters, some of whose descendants are still in use
today.
This page has a few beautiful photos of incredibly detailed Mi-6 scale model, built by Bernhard Pethe:

While the Chinook certainly appears odd, and the MI-6 is damned huge,
other big helicopters begin to look like the designers were not trying
for size as much as just plain weirdness. Take a gander at the
imaginatively-named Soviet MI-10. Although its guts were from the
old, reliable MI-6, this misshapen cousin sported four monster legs,
giving it the impression of a bug-phobics nightmare dragonfly. Whenever
I look at the MI-10 I always wonder if the pilot ever forgot what he
was flying and stepped out -- falling dozens of feet to the tarmac:

Not that the US hadn't had its own share of big, and damned ugly,
helicopters. Perhaps because it was created by Hughes, the same Hughes
of crazy-in-Las-Vegas and the Spruce Goose, the XH-17 Sky Crane
was terrifyingly huge: the rotors alone were 135 feet across (the
largest in the world). Imagine the jaw-dropping effect watching those
insane rotors starting to swing... and the whole Sky Crane taking off
like a half-transformed insectoid alien ship:

The Fairey Rotodyne, 1959, advertised as the "first vertical take-off
airliner in the world" (project scrapped in 1962) and the first
helicopter airline in the world: New York Airways, 1953
(images via)
"On July 8, 1953, a company called New York Airways began the first
regularly scheduled helicopter passenger service in the world. Operating
in a fashion similar to a bus line, the helicopters flew to sites such
as La Guardia Airport, New York International Airport, Neward Airport,
West 30th Street in Manhattan, White Plains, and Stamford periodically
throughout the day."
The biggest helicopter to date, and one of the very strangest.
Aside from the bug-geared machines like the Sky Crane and the MI-10,
most big helicopters usually look like smaller ones simply writ large.
Rotors? Check. Tail rotor for stability? Sure. Fuselage? Absolutely.
But the -- yet again -- poetically named Mil V-12 looks nothing like anything before or since:
Click to enlarge to see detailed view (from Russian TM magazine):
Sure it has rotors -- it wouldn't be a helicopter without them -- but
with the V-12 they are placed on the side of its massive fuselage.
Weird, right? But this is BIG weirdness as the V-12 is commonly
considered to be the largest helicopter in the world. How big? Think
of it this way: see that 747 over there -- that monstrous fixed wing
machine? Well, the V-12 is as wide as one of those 747s. But unlike a
747, the V-12 can take off straight up, and haul close to 55,000 pounds
at the same time -- or 88,000 if it takes off a bit less like a
helicopter and more like a plane.
"On August, 6th 1969, Mi-12 has lifted cargo in 44205 kg on height of
2255 m, having established a world record of load-carrying capacity for
helicopters which is not beaten till now."

Mi-26: The biggest operational helicopter in the world
Don't get close, or even approach it when the rotors are spinning: "this
chopper's wash will pick up and fling rocks, up to 12 inches in
diameter, around like leaves!". With a crew of six, this "Halo" (NATO
reporting name) mega helicopter can carry 70 passengers, or a flying
laboratory, or a whole dump truck, with space to spare...

When compared with a typical Chinook, Mi-26 does indeed look big:

See a detailed chart of this craft on this page. Still, Mi-12 is significantly bigger than Mi-26 (however, Mi-12 is not in operation, which is really a shame, if you ask me):

Mi-26 lifts the MH-47e Chinook in Afghanistan (left image), while
Chinook stars in an incredible rescue operation, confirmed as true by
Snopes (details here) -
"November 2003, a U.S.-led coalition launched Operation Mountain
Resolve in the Nuristan and Kunar provinces of Afghanistan. The
above-displayed photograph of the precarious-looking rooftop landing by a
CH-47 Chinook helicopter was taken during that operation by U.S. Army
Sgt. Greg Heath. The Chinook helicopter is touching down to receive
Afghan Persons Under Control (APUC) captured by members of the U.S. 10th
Mountain Division"

We've also received a tip that the "Largest helicopter that has been seriously proposed"
was, perhaps, The Hiller-Copter, which is featured in Hiller Museum in
San Carlos, California. The museum has documents and a film from a
(semi) serious proposal from Hiller to recover Saturn V booster stages
in midair, using an enormous helicopter. The exact helicopter specs we
can't locate, but it was something like a 200 foot rotor turning at 10
RPM, with full-sized turbojet engines at the rotor tips. Here is a
history of the Hiller Aircraft concepts, and more info
"Here's your helicopter coupe!"
As for the smallest helicopters, nothing beats this concept from Popular Mechanics Magazine, Feb. 1951:

Compare it with the diminutive and very practical Soviet Ka-26
from the early 1970s (you could attach various functional blocks behind
the pilot's cabin) - see image above, on the right. And then, there was a
Hiller XH-44 Copter, which Stanley Hiller, being 19 years old,
designed, built and succesfully flew - in 1944! - making it "the first
helicopter with coaxial rotors to fly successfully in the United
States."

Carter Copter: looking into the future
Carter Copter
is the proverbial small company "that could". It's been around for long
time, and delivers results: their signature mini-copter has flown
faultlessly since 2002 (more info here)
(images via 1, 2, 3)
On the Russian side, things were really looking into the future with Ka 58 Stealth Helicopter
- "Black Ghost" (it looks too good to be true, almost good enough for a
cool videogame - and, yes, it remained a concept... but pushed design
envelopes for other models). "Ghosts" hardly die completely, so perhaps
this stealthy creature is being resurrected. Your guess is as good as
mine.
Next time you see some draconic monstrosity fly overhead, don't jump to
conclusion that this is an apocalyptic Angel of Doom, or worse, casting a
crooked shadow on the cowering world below. It could be just one of
these giant helicopters, on a mission from... well, judging from
thrilling picture below, some of the missions could be pretty intense,
indeed:
