It does indeed ..

love this line too ... " damage prevention systems included" .. Hhhmmmm

Can see me with one of them .. prob a tad booring to fly , but great BLING !!

Scored one of these for xmas,
it is certainly different to fly and has come in handy for indoor flying with the crap weather we have been having lately.
is very stable, creates an amazing amount of downdraft which can lead to quite a bit of turbulence in small areas.
forward flight is fairly slow as is the piro rate, but the thing looks damn awesome in the air :cool:
only issue so far is that it seems to be a power hog, sucking the supplied 3s 800mAh battery down in about 5 min.
I've pushed the pack to far every time as it is sooooo hard to stop flying:D

I dont get it, whats with the dual Co-axial rotors? A real chinook http://en.wikipedia.org/wiki/CH-47_Chinook has counter rotating blades (front and rear rotating in opposite directions and thats why they dont need a tail rotor). So whats the point? Its just like 2 twisters joined together.

Errrr, so your rc car is just like a real car Eh :confused:




So whats the point?It's a toy helicopter, you put a battery in it and fly it around.
the twin dual rotors remove the need for complex electronics and mechanics, giving it a price of about $250 as apposed to spending many thousands of dollars for a more realistic one with two single rotors.


Its just like 2 twisters joined together really, I hadn't noticed

I didnt mean it like that. I know there is a difference between a toy and a real one. And I know the point of the RC chopper is its fun (I have a twister Medivac). I was asking whats the point of the dual coaxial rotors? What the difference between having 2 blades counter rotating directly on top of each off or one at each end of the heli? I was just trying to get an understanding how they work. I wasnt trying to bad mouth your heli, I have been tempted to buy 1 myself since I saw them at my LHS.

The man does have a point, I wonder why they didn't make it with counter rotating blades but one one way at the front and the opposite way at the back, must have been to difficult to make or fly or something..... theres one on youtube, its like two trexes joined together, looks pretty damn cool, I'll see if I can dig up a link.

thought this was a fair explanation

Thats like comparing chalk and cheese mate, any .50 size heli will cost considerably more than a micro electric. Surely it couldn't cost a substantial ammount more to make this thing with counter rotating blades back and front, it couldn't be much different than having 2 sets of 4 blades spinning oppositely?

to ask such a question I really don't think you understand the complexity of it.
chalk and cheese is right, it would need variable pitch blades, a radically different head with many more moving parts, gearboxes, drive line etc..
It would cost way, way more to produce regardless of it's size.
follow the link i posted and have a look at the pic of the airframe and compare that to any counter rotating heli

A duel counter rotating helicopter is about as basic as you can get, with fixed pitch and very few moving parts. their a fun, easy to fly and affordable choice for entry level fliers.

Yeah true, I never really thought of the variable pitch blades and heads, it is quite complex.

Well that answers my questions:). The $3000 one looks awesome, it would be a bit harder to fly, especially in the living room:D
