The quadcopter is an aircraft with three or more rotors based on a helicopter system. One of the leading companies for the production of unmanned aerial vehicles (UAVs) has become a Chinese company DJI. Her series "Phantom" (Phantom) has gained the greatest popularity among similar devices of amateur level. The popularity was ensured by high-quality development and ease of operation. According to the instructions, "Phantom 3" transmits the image from the carrier camera to any mobile gadget that has Wi-Fi. The entire line of "Phantoms" is intended for making photo and video shooting in the field of amateur use, for entertainment and leisure.
Phantom 3 Aircraft
The developers of the Chinese company are not particularly "confused" over the appearance of the flying device. The line of the third series is practically no different from the second.
The case is presented in the form of white plastic, rather good quality. There are golden stripes on helical structural beams. The screws themselves are self-tightening. The technical characteristic of Phantom 3 implies the presence of a camera on a three-axis suspension in the lower part of the body. There are mounted visual positioning tools that allow this model of the flying device to move in closed airspace without GPS navigation.
Visual and ultrasonic sensors located on board the aircraft operate on the principle of sea sonar. They "probe" the environment under the apparatus, maintaining the necessary safe height.
The unmanned device has a pair of landing mounts, which also perform the protective function of the camera during a hard landing.

The cheapest modification of the Phantom 3 is sold at a starting price of $ 799.
The package includes: assembled aircraft, remote control, rechargeable battery, charger depending on version, spare screw blades with storage case, cable for connecting to a personal computer, various documentation. Options, except for the memory, does not depend on the model.
Modes of use
One of the technological innovations in the characteristics of "Phantom 3" should highlight the optional mode of following the user. Previously, this option was already used by the developers of the Chinese company DJI in their products.
This mode has gained wide popularity among owners who engage in extreme sports - snowboarders, skiers, motorcyclists, cyclists and others. Such athletes travel long distances and are often not always accessible to spectators. A quadrocopter will help demonstrate its achievements, successes or especially dangerous stunts, everywhere following its owner and fixing everything to the camera. In this mode, the device will move at a distance of 20 meters from the user and a height of 30 meters.
The flight mode by points implies flying around with a quadrocopter, previously marked on the map of places. The Phantom 3 drone will alternately move from marker to marker, while the user can concentrate on controlling the camera. This is very convenient if you want to capture the advantageous panoramic angles during the flight of the device.
In the Phantom 3 quadrocopter there is a course fixing mode. This function involves movement in one specific direction, regardless of the direction of its front. This functionality allows the device to fly along the object of interest.
Point of interest mode. The drone will circle above a given location, maintaining a height of 10 meters. The radius of the flyby will be 15 meters. Such a point can serve as a person or any building.
Quadcopter camera
The Phantom 3 camera is not inferior in its characteristics to the leading analogues of other manufacturers. Its maximum resolution is 4096 by 2160p, the so-called 4K resolution. The frame rate will be 25 per second. Also available in HD resolution (1920 by 1080p) at 60 frames per second.
The camera itself is equipped with a wide-angle lens with a focal length of 20 mm, the viewing angle has 94 °. Three-axis gimbal gives the image a stable picture.
Conclusion
The line of quadrocopters of the Chinese company DJI of the above models turned out to be successful. Especially worth noting is the Professional modification of Phantom 3. The owners' reviews are full of laudatory comments about its technical parameters, camera configuration and charger power. Many liked the optional flight modes, and for some extreme players, the Phantom 3 became an indispensable gadget in their classes.
Only a little discouraging, according to potential owners, the cost of the device.
