Everything comes from China products reviews site purchased in China
I already bought four helicopters in DealExtreme and this is, without doubt, the best of them.
What differentiates this model is the presence of lateral engines that stabilize the flight.
But to sum up, It is quite similar to any other Chinese helicopter: gyro, infrared control with six AA batteries and operation restricted to indoors (Although it is possible to fly in open space, It's really hard). 
The connector to recharge is better than most: round and similar to some Nokia phones. In the photo below the detail of the side engine.
Below the gyroscope and the two pairs of propellers. Much of the construction of the helicopter body is metallic while the vast majority of models is completely plastic.
Another differentiator of this helicopter's flight time, that comes to 10 minutes with fully charged battery, While most rarely exceeds 5 minutes.
When switched on, hardly the pairs of propellers, that rotate in different direction to stabilize the helicopter.
The two side engines also allow the helicopter fly sideways, What is commanded by two top buttons of the remote control.
On the front we have a high-brightness led and back an led that flashes red and blue.
The infrared receiver is located at the bottom, like most models.
Detail of the rear engine that tilts the helicopter to move forward or backward.
The remote control operates on six AA batteries and has two analog and two top buttons, In addition to a rotating control, a on-off switch and a control button.
The left analog stick controls the vertical thrust of flight, already the right-analog stick controls both the forward and backward motion as the rotating clockwise and counterclockwise.
On the back of the control we have the battery compartment AA batteries. You can use rechargeable batteries without problems, fairly hard.
At the top of the control we have the infrared leds and two buttons that make the helicopter fly sideways, to the right or left.
I made a video showing the helicopter's flight, see all:
In Dealextreme this helicopter continues with great price and there are still three color choices. Those interested can follow the links below:
How do I request for Brasilia-DF? What is the value ?
The DealExtreme sends to any location of Brazil. The Helicopter is costing $ 28.99 with freight. Payment by card or PayPal. Link at the bottom of the text.
I wonder if it had to pay import transference rates
Helicopters are typically packaged in large boxes, which increases the chance of being taxed. I, Luckily, I wasn't…
