Jan 21 2008R/C Helicopter Is Crazy, Operator Has Skills

Last

Cameraperson was awesome!!

Are you sure it's real? I don't understand how it can stand in vertical position without falling! Whitch rotor makes it fly then? And who is this guy? Is he from outside the matrix?

yeah, it can't be real

asshole!

I agree with Klouche... what's generating the lift when the heli is vertical...
did you see some of those accels and decels... there must be one crazy ass motor in there to generate movements like that... shit... imagine the controller's reaction time... it has to be like .001 seconds!!! Ain't no way in hell that RC can fly backawards with the center of grav location... And last... you show me heli blade that generates lift upside down... i'm not even sure if RC helis have a blade pitch control to fully reverse the pitch to fly upside down (i'm gonna be bold enuff and not even google that tidbit)... fake... do some more research... or at least provide your basis for saying it's real!!!

Yeah, it's real. Take it from me.

Yes RC helicopters can fly upside down, this is possible by a servo that changes the angle of the main rotor blades allowing it to fly upside down or at right angles.

It is absolutely real. I fly the smaller version, and they are more than capable of doing that outrageous of 3D flying.

The brushless motors and batteries used in these things are incredible. They well draw, and supply in excess of 40 amps of power. More than enough juice to generate damn near instaneous acceleration/deceleration changes.

All 3D capable Helis have fully articulated heads capable of negative pitch. Most are able to run +15 degrees thru -15 degrees. Two of my heli's are setup for +10 to -7. And I have no problem hovering inverted with those settings.

Response rates of digital servos are in the neighborhood of 250 hZ....meaning they will have response rates of 250 movements a second, if the input is there.

Hovering the heli in a near vertical state is actually a slight illusion. Whats happening is that the heli is being "bounced" from leaning one side to another. The pitch and head speed of the rotor is "fluttered" between high and low to generate sort of lift "pulses" . The lift is always applied normal to the disc, so at those high angles of attack (approaching 90 degrees) the amount of lift needs to be very high to produce enough lift to keep it up on that very small vector. Your basically "juggling" the heli.

Its VERY hard to do right and make it look smooth, but its more than possible. Having seen this type of flying first hand, its incredible, but its real.

Ok... i stand corrected - http://www.youtube.com/watch?v=Ctzd3A1ZJrk

was that an gas or electric helicopter and who makes it and what model

This guy has the loneliest penis on earth.

Michael -

The Heli in the video is a Align Trex 600. It's Electric Helicopter. It will run you about $800 - $1,200 (without Radio) for the build, depending on your choice of components. Its a beast, using 600mm rotor blades, making a total disc size of nearly 4 feet across.

UFO?

When many people describe a UFO they have seen, they speak of abnormal or unexplainable movements and changes in Vectors. The starts, and stops, and quick changes in direction his copter does are like many many lights you see on UFO tv shows.

If the military has larger craft with capability like this RC copter, that would explain a great many UFOs. They wouldn't even have to be full size craft. Just somewhat larger and still radio controlled.

@ steve

It would prob kill the pilot too... perhaps a uav....

O_o

indeed very spectacular

its a very interesting point you made steve
If these things were possible on a larger scale, it would explain a lot of UFOs, but then again with larger scale comes more weight with the materials involved. This means more forces involved to accelerate/deccelerate the object, and it doesn't neccessarily depend on engine capacity and power... we're talking more about the physical forces involved such as G-force.
I guess you've seen videos of planes' wings tearing away after pulling up too hard.

I'm not much of a aeronautical wizz, but thats generally my opinion.

Yeah, it only works on a small scale; on any larger craft the stresses would be too high for any maneuvers like these.

@matt, #8, Thank you!

I was trying to figure out how the heck that worked. rotating the heli blades along their long axis, brilliant, simple, and restores my faith in the laws of physics!

sure, but does it smell like a vagina? no.

Number 12

I'd rather have a guy who has the money to buy something like that than one who doesn't. I doubt he has a lonely anything.

Very neat...I was going to give a reason or two as to why this is real, but #9 did a good job. I've done research at getting my own RC aircraft, like the amazing F-22, and the amazing apache helicopter (gas-powered of course). In any case, it's neat stuff.

Dear Sir,

If you do not mind, may I know the components model use for the above TREX 600 Video as follows :

Servos
Rudder Servo
Gyro
Motor
ESC
Blades , CF or Wooden Blade
Main Battery Pack

Thank you and waiting your reply.

Best regards,
Budy

Awesome flying. It reminds me of how dragonflies change direction in that twitchy, quick way. I also like that snort sound it makes when the pitch changes a lot or goes negative for an extra burst of thrust.

Dude. Forget the pilot, the cameraman was AWESOME! I can't believe he never loses that thing, flying around like a freakin dragonfly. Bravo, cameraman.

a real helicopter cannot actually do all that. the r/c helicopters have aditional range of motion in the swash plate, allowing crazy stunts, even flying upside down! a real helicopter has a very limited range of motion in the swash plate, they only flip upside down if someone really screwed up their flying and got leverage off of something, say meybe the skids hit something. i think military attack helicopters can flip if the stick is pushed too far forwards.

wow....
