We have never seen such a concise fashion design rotor aircraft. Phantom 4 is pure white body design, with four silver motor and in the middle of the “DJI” Logo looks very bright eye, and the phantom series overall appearance has not changed much but Phantom 4 weight is more than phantom 3 series contains the battery and 1380 g four OARS.
Phantom 4 wheelbase reached (refers to between two motor diagonal) 350 mm long, adjacent blades rotating, maintain a certain distance air kinetic energy efficiency does not have a negative impact, and the characteristics of the four largest elf is the visual recognition system, can see the front bracket, with binocular cameras, mainly be responsible for the identification of forward-looking level 60°, barrier of plus or minus 27°vertically, of course, a certain range and environmental restrictions. The first is the strength of the GPS signal. The second is whether the visual system is strong. The improvement of the Phantom 4 over the Phantom 3 is that the two pairs of “eyes” are in the front.
Flipped the elves 4 can see “stomach” part, shock absorbing silicone material covered on both sides of the stents and consistent with the yuntai part of light gray. The whole “stomach” was full of pores for unmanned aerial vehicle (uav) work to normal heat dissipation. In the lower visual system, four “eyes” are in the spirit 4, the larger is the ultrasonic sensor, the smaller is the binocular camera, and the height and position recognition accuracy are improved.
It is worth mentioning that the Phantom 4 under the visual recognition in addition to more than Phantom 3 a camera. Two ultrasonic sensors advantage lies in the face of transparent liquid, mirror material, binocular cameras even failure can normal recognition. That means you can use the Phantom 4 drifting on the lake no danger and the phantom 3 may be bumped into the water.
Rack is the core part of uav aerial camera, four elves with new a 94 °FOV, f / 2.8 aperture of the lens (with UV mirror), effective pixels, 12.4 million, as many as four photo models, lens progress is compared with the Phantom 3 added a set of filters, fell to 36% and the lens distortion, very suitable for in the grand scenes, Mavic cry inside in the toilet), color reduction performance is stronger, and the highest can record 24/25 p 4 k video.
The battery position is held in two – side clasp, with four power and power indicator
Phantom 4 5350 mah lithium battery of 4s, fool proof design, type of LiPo4S (number, the higher the voltage), both sides have thermal barrier layer, battery at high temperature is a good way to heat dissipation, life for 28 minutes comparing 3 increased 25%. Actually use the surplus of a certain power is normal, general fly about 20 minutes).
The motor of the Phantom 4 is the same as the iron in the two diagonal motors. The installation requires a circle of color corresponding to the blade.
The ventilation cooling port on the arm is used to protect the dust with a very thin iron mesh, and the transparent part is the navigation light (all four corners).
Phantom 4 9 inches, quick release propeller installation method is simple, the corresponding color of the motor can lock down a twist, largely avoided the elves 3 using the tight slurry will be shoot oar phenomenon (design problem is not to say, but changed the user habit of propeller).
The Micro USB interface on the fuselage and the SD card slot, the direct bare design lacks a bit of beauty.
The Phantom 4’s remote control is also designed with bright white design, and the other is like a lunch box. Small make up personal think consumer unmanned aerial vehicle (uav) is accepted, the control mode is simple and convenient is also very important reason, mobile devices and only need a cable connection between the remote control, embodiment can become a professional flight monitor (a row of small lights below shows power and state).
Remote controller bracket support 9.7 inch top mobile devices (the Air2 okay), the playing card buckle fixed way, strong adjustment stent size is convenient at the same time, the bracket folding twist screws can move in the middle of a word.
Remote control operating frequency range is 2.4 to 2.483 GHz, using GPS/GLONASS double mold positioning, maximum signal range is (FCC: CE: 5000 m 5000 m without interference, without sunscreen), no chance to according to the GPS coordinates, automatic switching rf power standard lies between the FCC and CE (mainland China). Remote control adopts the design of 6000 mAH lithium battery 2 s life aspects according to the small make up for personal use, there are no pressure about four to five, in addition elves 4 USES is xinjiang Lightbridge Gao Qingtu transmission technology, the highest support 720 p @ 30 FPS.
The rocker, on both sides of the remote control with automatic back design, small make up accustomed to using the hand (refers to joystick control mode, popular culture is set the joystick control channels), and metal sharp rocker cap is helpful to precise control and prevent hand slide. Below is the remote control switch and automatic return button, short press + long press 2 seconds, can open the remote control, positive is so simple, not as complicated as aeromodelling dedicated multi-channel remote control, remote control itself, the operation is simple, put most of the functions and technology to mobile devices and integration within a machine, users get started so simple.
Antenna gold-plated interface design can reduce interference (this is not elves 4 original antenna, is small treasure to buy X enhanced antenna), it is important to note players in flight, better be antenna keep parallel with aircraft in order to get good signal.
The top button of the remote control is the pause button (which allows the uav to hover quickly), the camera button and the shutter EV value to adjust the scroll wheel.
The button on the other side is the mode switch (A and P, as well as the S) button, the video record button and the Angle adjustment of the cloud platform.
The metal support rack at the bottom of the remote control and the silicone pad.
Phantom 4 charger, can for rechargeable battery and remote control at the same time, the battery pins adopts the design of both positive and negative, the user need not consider also don’t have to observe the connection interface, can be quickly according to the personal use of small make up (the battery remote control in the remaining 25% power, for example), full of an elf 4 batteries need 60 minutes, with the remote control requires more than 70 minutes, for many users recommend buying battery butler (more than the battery to charge) in turn.
Micro USB cable and USB OTG for upgrading firmware and connecting mobile devices
The complimentary lakesha 16GB Micro SDHC memory card, U1 standard is very suitable for high-speed shooting

DJI GO APP experience: mature drawing control interface
DJi, there are average GO and average 4 GO two graph APP, average 4 GO for 4 series, Mavic Pro is the Phantom and Inspire 2 new models, and the average GO 1, the Phantom, applicable to Inspire Matrice, OSMO and Mavic Pro, average 4 GO show new detection radar map, returning obstacles detection, chirping of stop electricity, as new features (very useful), but small make up in order to take care of most of the players on average GO to share what functions need to be aware of.
Enter the average after the GO APP, is concise and clear interface, even beginner can locate what you want to do right now, the upper left corner of the “plane” symbols recording the detailed flight record, very important small make up to three times, record of unmanned aerial vehicle (uav) after the lost find flight! Unmanned aerial vehicle for flight record! Unmanned aerial vehicle for flight record!
The record list has a very detailed flight record
The record has a very detailed flight record
The editor can transmission drone photographs and video in real time.
Main interface “caps” icon in the top right corner is the Dji for newer flight academy, which has a real scene of the flight simulation novice, detailed video tutorials. Older drivers had the better have a look because the coverage of “bomb” in the drone is high.
DJI GO figure of the interface is not complicated though it may show the various state index of information alone is complicated. The top area of the icon from left to right in turn is a GPS/GLONASS double satellite signal strength. The compass letter, remote control, HQ picture and aircraft power signal, and the parameters of the left shows the vehicle real-time height, distance and velocity, etc. The left bottom corner and right bottom are aircraft radar and real-time positioning map. We should be paid to the aircraft flying in over-the-horizon, judging direction in addition to the use of cameras, radar direction with map is also a kind of method.
Before you take off, be sure to check whether the vehicle is in normal condition. In the upper right shows the location of the “4” Phantom click into the vehicle status list, focus attention to module self-checking, compass, IMU (inertial measurement unit), electrically controlled state, haeundae state is abnormal, of course, but also pay attention to the temperature, power and aircraft when only the best P at the beginning of the new model for flight, flight control is one of the most stable at this time.
The spirit 4 provides the Japanese hand, the American hand, the Chinese hand and the custom four kinds of rocker modes
Elf’s perception of the 4 set, it is suggested that the first and the fourth is open, can avoid the collision probability, to a certain extent, and advice when flying around about strategy, it is best to craft the open when there is obstruction in enough height or above is preferred, or up to bypass without depending on the visual system, may encounter obstacles above; Intelligent following is also the same principle, such as branches, antennas and other small objects, the visual system cannot recognize.
In order to avoid rookie misoperation, the mode switch between the remote control and the DJI GO flight control parameter is a nice feature. Take off its height must be set high enough (to avoid accidental encounter obstacles), small make up general advice about 100 meters is enough (depending on the place environment), high limit options in the current version of the DJI GO in, because of the many urban areas are limited to 120 meters, perhaps only in some remote areas not management can play a role, new beginner can also open the new mode, to adapt to the feel of remote control of unmanned aerial vehicle (uav).
Shoot the sample and video: humanized shooting Settings
The preparatory work
In order to find the beautiful scenery city, we come to foshan (China one of largest city)two landmark buildings located: the lotus sports center and the lingnan pearl gymnasium, originally wanted to go to guangzhou pearl river new town but know there already ban, shooting a group of photos and video, you to feel the charm of the aerial together, the picture above is the original didn’t modify (relatively true), the following pictures are simply changed the saturation, contrast and brightness (relative to the eye), between the two there is no absolute good, style is, after all, turnip greens, his taste.
Century lotus sports center
Dongping river (yuntai FPV mode)
The nearby take-off secret base, the concrete reinforced concrete structure actually quite affects the normal work of the compass, later on “the second floor” is better.
The bridge side
Liannan Pearl Stadium. The light was not opening and the scene is not good.
The beauty of city lights
Phantom 4 all aspects are very friendly to the newer. The first is the parameters of the camera settings humanized, fixed aperture ISO and exposure time according to the environment (value) according to the EV, pay attention to the lower left entirely in the horizontal line (wind speed) should be relatively stable, moreover yuntai using three axis design itself can eliminate a certain degree of jitter, as long as pay attention to master certain shooting skills, it’s easy to take a clear photo and video. Productivity of science and technology and content up to now, even the aerial humanizing is really a very happy thing, think that year small make up also for how to install cameras on fixed wing, spend a great mind.
Said flight feeling again, at that time there was a time when small make up took off is on the roof, the wind speed reaches level 5 hover is still very robust (like big jiang claims), but where is the roof of reinforced concrete structures, the more influence the compass calibration, suggested that readers choose open ground take-off. In indoor flight (generally no GPS signal), even with the visual system have to be careful, if suddenly dim light cause visual system failure, will profile switching mode, the aircraft don’t hover will automatically inertial motions, comparison test of fly hand manipulation ability.
Conclusion: towards intelligence and humanization
As a mature technology product of the fourth generation of dji jinn series, we feel that the personal aerial camera is moving to a more intelligent and humane era. Such as multiple function such as obstacle avoidance, automatic return, show flight appeared to be more intelligent, and simple manipulation of aerial and figure and more humanized interface, elves 4 currently single 6999 yuan price, for individual aerial elves 4 meet the demand of various aspects (a bit is not portable, can choose Mavic Pro), and for the first time contact of uavs fly, try the elves 3 series also is right choice, the price also cheaper ($1850).
