What is a helicopter able to do and perform ?
 
Since many people praise the Bo105 for its stunts and fancy here for it, I have to admid that I think people often forget that any articulated rotor is capable of doing so.

Here is a video evidence of a normal bussiness helicopter doing a perfect loop and a roll.

Should I mention that this is one of my favourite rotorheads of all or at least the military sister of this civil bird ?

Yeah, about that OH-58. . .

Helicopter tech has come such a long way since the, at the time, ultra innovative Huey. It's no surprise to me that an everyday helicopter can do this stuff. Still gonna file it under "it can, but you shouldn't" lol......

I'd say that's got a pucker-factor of black-hole/10.

Yes, it is truly amazing what helicopters can do ... so much more than anything with a fixed wing!

For example, many people don't know that technically helicopters can sustain inverted flight if the range of blade pitch is simply configured to be negative as well as positive.

By far the biggest limitation is the people inside them. This is obvious when you watch RC helis, which show the true potential, such as the one in the link below:

I fly RC helis (but my skills are nothing like in the video), and I can tell you this is not electronic trickery. It took hours of practice for me to learn just to hover with any confidence ... and many more hours before I could fly backwards or inverted. Very stressful hobby ... hence the appeal of flight sims like DCS with it's low cost per crash!

And that's what?
It looks like you're confusing what people do with a radio controlled helicopter, and the piloting of a real helico.Even if we are able to pass the loop with a real helico, it is not for nothing except to amuse the spectators. The majority of the players focus on this kind of exibition, to reproduce them in the game, whereas they are hardly able to hold a correct stationary without the auto piloting. If you want to make a simulator RC Helicopter, say it frankly, and stop enjoying the amalgam, please.
Any aerodyne is able to pass a loop or a barrel, that does not mean that it is made for that. A helicopter offers so many possibilities, it is really a pity to reduce it to a simple figure of aerobatics .

Do you know what happened to the airframe after that flig... incident? ;)

Comparing an RC scale helicopter with a 1:1 helicopter is not fair. One thing to begging is its different mass, there is a huge difference there... Other are the materials and stiffness/resistance of those...

If you try to sustain inverted flight with a helicopter (I mean, one that was not designed for sustained inverted flight, some helicopters have negative pitch, normally shipboard ones) you would probably lose your tail and rotor blades in the process.

I am a bit tired of people here, in this forum, comparing RC helicopters with real helicopters. Although the fundamentals of flight are there, you can't compare the inertia and the mass, plus the different materials and dynamics... Everyone has right to express opinion and its up to people wanting to learn more and get the facts right. Cheers.

@focha:
Yes we do, cause we have a maintenance guy onboard that send me the link to the video and we discussed it. Not uch happened to the airframe itself. It was checked more into the depth but that is it. Nothing roke or anything, and the magic to such flight is a simple one. Do not cut your tail ;)

@cromhunt:
Sorry you have misunderstood me. I certainly have no desire to emulate RC flying in DCS; other simulators exist for that specific purpose. I enjoy DCS (and other flight sims) as a totally separate hobby; the purpose being to experience realistic on-board fight and procedures from a pilots perspective.

@Focha
Comparing any two classes off helicopter is unfair.
I interpreted the OP ("What is a helicopter able to do and perform?") in the broadest sense of the subject, and to push the limits of what a helicopter can do inevitably requires some type of specialization. For example, a Mi-26 can lift 20 metric tons. Does this demonstrate what amazing things a helicopter is capable of doing? Yes. Is it a fair comparison with other helicopters? No.

By definition, a helicopter is not restricted to any particular size, nor is it required to accommodate a pilot. But in hindsight, yes I should have perhaps considered this question more purely in the context of DCS (where the subject matter determines that a pilot must indeed be present on-board). So I apologize if considering a slightly broader scope offended anyone. But I won't apologize for my love of helicopters (of any shape and size!)
