If he ever gets his pilot licence I do NOT want to be on a flight of his...

95% sure it's NOT what was actually filmed. Some of those things come close to breaking the laws of physics (if you set some assumptions about how much power such a small model can generate), so I'm going to call it " 'shopped " (well, you get the idea).

I want to say that, but at the same time it was too damn cool
but it is pretty much a motor attached to blade + stabilizing blade, and just had a helicopter skin. so it should be able to do quite a few things that would be impossible for a helicopter.
ah well I'm way too tired to try and reason this out any more You're posting again!? Has it really been 5 mins?

Bumblebees also defy the laws of physics, or at least aeronautics, so I'm gonna call it real. Doing it in an actual helicopter is a sure way to enter the Darwin Awards.

No shopping. I've seen (in real life) RC helicopters do a lot of that stuff. It does have to be very light, powerful and with a fully articulated rotor setup. As for its size. It's full-sized as RC helicopters go. And the engine/weight ratio is usually insane on RC helicopters that are made for air acrobatics. ______________________________________________ -My respect can not be won, only lost.

Pretty much this. RC stuff, especially helicopters, can be made out of incredibly light materials.. because well, if it crashes, you suck anyway :p if that had hit the ground even once, chances are pretty good it would never be able to do any of that stuff again.
One main thing to note is that the main rotor of the helicopter actually tilts, it can be horizontal, or tilting both ways. this allows it to produce lift both 'up' and 'down' as required.. On a real helicopter, the rotor will barely get horizontal, let alone reverse..
Also, your run of the mill stiff breeze would have given him sooo much trouble Blane Xero > Lance is at -0.9 sec status with a 1 million bounty. LAnce is also amarrian. Thats 3 evil points |

Not really... that's just something a physicist (or was it an engineer) blurted out after some back-of-envelope calculations (while probably buzzed or even downright drunk) more than half a century ago to some biologist, thing which the biologist then proclaimed as "stuff physicists claim" and it spread like wildfire (and it's still quoted today as "fact") even if the original "creator" of that mistake recanted pretty soon after he realized bees (insects in general, actually) don't work like birds (well, most birds anyway).

I suppose it's at least theoretically possible (that's why I didn't claim a 100% certainty), but they're so many in such quick succession that it boggles the mind somebody could manage it all "live" and with no computer assistance.
I mean, just look, for instance, at one of the first few things he does, at about 1 minute into the vid : he's "parking" the helicopter tail-down, rotot-axis near-horizontal. Both rotors in this case can only "push" on a near-horizontal direction (he's actually tilting it from side to side about 30 degrees tops), the main rotor has to be the only driving force while the bottom rotor has to apply next to no force at all (just enough to counterbalance the rotation from the main rotor), so even if he would start applying max deflection at the exact moment he needs to (one direction for half bounce, the other direction for the return bounce), he's only got at best around 20% of the motor force in the direction he might want overall, and has to correctly counterbalance it with the tail rotor at the same time. If that would be real, it would mean he's basically balancing it dynamically in a way as if you would keep a long stick vertical by tossing it (without tumbling it) from one hand to the other.
Oh, and talk about a powerful engine (or better said, thrust to weight ratio - 5:1 wouldn't really cut it, you'd probably need closer to 10:1) and some damn impressive batteries... I mean, the model must weigh at least 3kg, so the main rotor should be able to lift//hover 20+ kg of payload other than the helicopter itself to be able to pull something like that off - if anything, THAT is even more impressive than the actual flying.
And that one is one of the easier ones to pull off, I'd say, since he'd basically just have to find the right ratio of throttle between the main and tail toror (which he already knows) then flip the pitch on both at exactly the precise moment several times over, while also controlling the overall power to counterbalance the heli's weight... like I said, that's just one of the EASIER ones.
In order to pull all of them off, he'd need to be able to independently (and very finely, crisply and suddendly) control power and pitch of both the main and tail rotor, all at the same time... so absolutely precise control and timing of two two-axis joysticks (I can only assume that's the control scheme), for a long period of time, with the tiniest of mistakes (in both position and timing) being quite literally a deal-breaker, with no chance of a do-over... ouch.
So... all of this we saw... he does it on a "test run of a new engine" ? And this guy managed to place THIRD place in some RC helicopter contest ? What the bloody hell can the better two guys do ?!?

I was totally doing that in my Abaddon earlier today. So take your "amateur" and shove it.
That was pretty great, except because of the name of the site I kept expecting him to whack himself in the face with the thing. About the bumble bees and other flying creatures of that nature I saw something once where they basically created so many multitudes of vortexes with the beating of their wings and they are so light that they kinda just hang there in the middle of it all. -Jin Nib Trading on behalf of Opera Noir since: 2009.03.02 03:53:00

Another one but from a different uploader.
I get the feeling these videos are speeded up. In this last one you can see cars in the background, still hard to tell though. It's kind of in the uncanny valley but for physics instead of faces. Here's a good example of what I mean.

No computer assistance, but on that particular model (T-rex 600) the tail rotor is auto-compensating. Basically clever mechanics. ______________________________________________ -My respect can not be won, only lost. It's given freely and only grudgingly withdrawn. |
