Product description:
Great Piece of Engineering - the 6-Channel CP Helicopter eh-V100D03BL
The smaller it is, the harder to make. It is a 6-Channel CCPM Helicopter, able to perform 3D aerobatics. There were a lot other Walkera models that can play 3D, but not at this small size. Factory faced a bit of challenge on this model, that's the Servos, they need to fast, durable, small and light, but they did it. Thanks to the Flybarless Rotor Head, it consumes less energy than ordinary flybar models, some people make ask, why they use Plastic for the Rotor Head. I would simply say for parts this small, sometimes it's more economical and better craftsmanship to use Plastic parts, since they came form same "Mold", to minimize the micro metal work error, which we've seen this kind of error in the past. For the 2.4Ghz receiver, it has a 3-Axis Gyro on broad, it did the job very well, it flies just like a "Big Helicopter" with Flybar, very impressive, and it's able to perform 3D aerobatics, soft and elegant, not "Hardcore" style. Another thing which will catch your attention is the agility of the helicopter, you move throttle stick upward and the respond is almost instant, no delay, it's because of the weight----light (54 grams with battery), so you get different feelings than other products.
