🕹 Review quadrocopter Phantom 4: what's on in the new bespilotnike

Positioning quadrocopter DJI Phantom 4

Company DJI - a young Chinese designer, began its history in 2006. The main activity - production of unmanned aerial vehicles, microcontrollers and various accessories for video shooting. The company is a pioneer in the sector of unmanned vehicles, and actively supported its development.

The range of products has several series quadrocopterAmong which the most popular Mavic and Phantom. All the Phantom series, to which belongs and protagonist of our article is positioned as drones amateur class for fun and photos and video.

Design and dimensions

Each new model series is becoming more streamlined and compact. However, to call a small drone is still not succeed. Overall dimensions are about 30 to 30 cm with a height of 20.

The total weight is equal to about 1.5 kilograms. Externally, flying gadget looks modern and futuristic. The most "fat" part of the apparatus is at the center, tapering to the rods propellers. Planting is carried out on the two arcuate racks, providing stability. control panel design is in the general style, and corresponds to the same lightness and aerodynamics. The remote features a stand for your smartphone or tablet, from which you can watch the flight online.

Operational characteristics quadrocopter DJI Phantom 4

And now a little about the characteristics and features of drone designs. They had a lot and look at what is.

Control system

Control as in similar models is carried out with remote control. Asserted radio reception range of 3.5 km. But video transmission for 2 km. The frequency at which the transmitted signal is varied from 2.400 to 2.483 GHz, that is, the nominal frequencies of Wi-Fi.

Feeds remote from the lithium-polymer battery 6000 mAh.

On the side remote from the front axle control levers are arranged. On the edges of the panel, there are additional buttons and controls. Protrude from the top two antennas.

Camera

The matrix has a CMOS camera type 12 MF, i.e. the maximum image size is 3000 by 4000 pixels. Snapshot mode a lot: Single, series, automatic and HDR.

Video is also supported by several standards: from HD to full 4K resolution with 4096 to 2160. On board the UAV disposed socket for SD card, flash card supports up to 64 GB.

sensors

Phantom 4 got a new obstacle detection system using two front sensors which operate in the region of 7 to 15 meters. At the same time they are displayed on the screen, even if you try to "fly" in this obstacle, smart electronics will not allow to do it. It is an excellent protection against damage for beginners who just started to master the device.

flight modes

The device supports 3 flight mode - P, S and A:

• P. Positioning. Mode of operation of the GPS signal. This mode is available for the following mobile unit, operates the function to identify obstacles and automatic navigation;
• S. Sports. Increased the maximum flight speed and maneuverability. It is worth noting that this is better to use a more experienced pilots, as a function of determining the obstacles disabled;
• A. The spatial position. In this mode off GPS, the system will use a barometer for the height adjustment.

We should also talk about the function return home. It will return the aircraft to the starting point, according to the latest records within the database. Procedures to initiate this function can be 3: predictive mode, low battery or accident.

Smart Auto mode simply returns drone home at the request of the pilot. And, if it was on identifying obstacles, it will bypass their own, bypassing or changing height. Emergency mode is activated by itself after the unit has lost communication with the control panel. But the low battery mode just as if the return of the UAV calculates that the battery is critical to return.

Features and Benefits

You can connect a smartphone, or tablet for camera control, suspension, configuration setting and t. D. For this purpose there is a special software available for devices on the Android platform above 4.1.2 and iOS 8.0 above.

Connecting your smartphone

Software

Management application called DJI GO. It is available in the AppStore and Google Play stores. With it you can control the camera, suspension, change the configuration of the device. We describe a little of the program.

Entering the camera mode, which is accessible from the main program window, you can access the live broadcast directly from quadrocopter camera. Right away, you can configure a bunch of functionality that affects the operation of the camera. camera control, recording, map mode, positioning, obstacle detection system, return home - in general, you can customize almost everything in the menu.

In paragraph Library you can find all the videos taken with the camera, select a template, or send data to the hosting service.

The Discovery section you can upload a photo or video, as well as view the status of the account.

Me item allows you to view the history of flight, use the DJI store.

Battery and Battery Life

Battery on bespilotnike DJI Phantom 4 called Intelligent Flight Battery. This lithium-polymer battery 5350 mAh battery. Its voltage is 15.2 V. Battery weighs almost 0.5 kg. The developers the maximum flight time of about 28 minutes. But it follows from user reviews and it rarely reaches 25 minutes.

Contents of delivery

Packaging machine very interesting. Firstly, there is a very quadrocopter and remote control it. Then there are 4 full-time and 4 spare propeller. Next is the charger and cable. There are also two different cable to connect the Android and iOS devices. And the most interesting - included is a handy carrying case and the operational deployment of the flight space. Well instruction.

User's manual

For a start it would be wise to read the instruction manual. It is complete, or it can be downloaded from the official site of the manufacturer. Then consider installing DJI GO application. It will expand the functionality of the camera drone.

Then you need to install the screws. As the screws rotate in two different directions, they have two kinds. Each marked by a special color. Screws with black rings must be installed on fixing points with black and silver screws - on mounting without any marks. To fix the screw enough to establish him in the seat and rotate. Reliability of fastening screws should be checked before each departure. The battery is inserted until it clicks.

On the remote control, as we have already mentioned there is a holder for your mobile phone or tablet. Inserting the mobile device you need to click on the lock to adjust the height of the stops so that the gadget can hold their own. Compound phone or tablet by using USB cable.

Next, we will present a list of features that are inherent in flight on 4 Phantom:

• when the obstacle detection system turned off, the unit will return to the base mode is not able to independently bend around obstacles. Therefore, the regime must be configured and active;
• if the drone is flying at an altitude of less than 20 meters, then going to the emergency return mode, the unit will first go to a height of 20 m is necessary to consider this fact when making the flight.;
• if the UAV is within 20 m from the starting point while in an emergency return mode, it begins to decrease and lands;
• it must be remembered that when the GPS signal is weak, the unit can not independently return to the starting point.

We would like to remind once again that should read carefully before using quadrocopter instruction and study all the nuances and peculiarities.

user reviews

Now worth a little look at what is written on the users machine. For the most part positive, only slightly diluted by negative reviews.

Here the user observes all the advantages of The Phantom of 4 compared to the Phantom 3:
