Some people play with UAVs not to take pictures of scenery, but to fly.
Dajiang DJI FPV UAV was officially released on March 2, and Dajiang set it as a new product, rather than the original traversing machine or aerial camera. The core selling points of the new machine are the strong to excessive O3 image transmission and the unique through rocker setting. If the previous aerial camera was used to take pictures of scenery, the DJI FPV UAV in Dajiang pursues the first person flight experience.
FPV is the abbreviation of the first person perspective of the First Person View. It is one of the biggest differences between the crossing/racing aircraft and the ordinary model aircraft. Dajiang also released FPV related products such as "DJI flying glasses, DJI Goggles racing version, FPV digital image transmission system". However, most of the original products in the FPV field need to be assembled by users themselves, so the threshold and operation difficulty are very high.
If we talk about learning such as programming, we follow the route of "starting from the beginning to giving up". In the FPV field, 70% of the users are "giving up after getting started". The goal of DJI FPV in Dajiang is to bring a more mature flight experience and greatly reduce the threshold of entry, "fly when you get there, without installation and debugging".
But one thing to say is that the audience of FPV/Traverse/Racing is much smaller than that of our geeks, so this experience is mainly to summarize important information, look at pictures, and see the details of the real machine.
Hardware parameters
DJI Goggles V2 ：
420g, detachable antenna, dual 2-inch screen, 144Hz refresh rate, field angle of view 30 ° - 54 ° (when answering official questions, it was mentioned that there would be customized service for myopia lenses, but in fact they can also be used with glasses)
The latest O3 image transmission, 2.4 and 5.8GHz adaptive dual frequency, has an exaggerated specification: 28ms delay, image transmission rate of 50Mbps, 810P resolution+120Hz refresh rate, and the longest distance of 10km
The microSD card with a maximum of 256GB is supported, which is used to store the image and video during flight. External 1800mAh battery, 110 minute life, 10W charging
DJI FPV It weighs 795g and has a diagonal wheelbase of 245mm. It is equipped with binocular obstacle avoidance in front and below, and ToF and fill light in below. Under the condition of 16 minute hover and 20 minute flight time, it can resist level 6 wind, with the maximum flight speed of 39m/s, equivalent to 140km/h. There is a gap between the speed and the traditional assembly traverser, but this is a 795g aircraft with a 20 minute endurance. I agree with this choice.
Image section It is a single axis mechanical pan tilt (rotatable range - 50 ° to 58 °), 1/2.3 inch 12 million pixel CMOS, 150 degree viewing angle (equivalent focal length 14.66mm) ultra wide angle lens. Up to 120Mbps 4K 60fps video can be recorded, with a super anti shake mode similar to the current mobile phone (using digital cutting to stabilize the picture).
Traditional remote control 346g, 9-hour endurance, 10km remote control distance. and FPV crossing rocker 167g weight, 10km signal distance, 5-hour endurance.
Price ， The DJI FPV package costs 7999 yuan, including aircraft, remote control, flight glasses, one intelligent flight battery, two pairs of blades and other accessories. The price of FPV through rocker is 999 yuan. DJI FPV Changfei accessory bag costs 1899 yuan (2 smart flight batteries, 1 charging butler). DJI FPV is also provided with DJI Care service, which is 1199 yuan for the one-year version and 1999 yuan for the two-year version.
DJI FPV remote control 2
The "folding" antenna has a rocker storage position on the inside of the handle. The rocker screws are very small and thin, which is a bit eye-catching to install. Provide normal, motion and advanced manual modes:
The first two modes are common on the Dajiang UAV, but now they can be associated with speed. One hand control can make the aircraft turn coordinately, while the motion mode provides an additional speed control function;
The advanced mode is the "full control mode" familiar to FPV players, which can completely unlock the posture. The operation habit is also completely different from the common American/Japanese/Chinese hands, and it is very difficult to get started. For safety, the lifting mode is different, and the secondary operation is required to unlock (the default state is only 45 degrees).
It may be that considering the experience threshold of FPV, its app has a complete flight simulation function (strongly request to be lowered to other aerial models) and tutorials.
For safety, obstacle avoidance safety assistance takes effect by default in both normal and sport modes. Both traditional remote control and somatosensory remote control have special "one button brake, intelligent return" button. Including in advanced mode, in case of misoperation or muddling, the machine can immediately switch to fixed point suspension state under any circumstances.
Crossing rocker
Passing through the rocker is a bit like the handle of VR glasses. The trigger controls the "accelerator" and the lift/rotation/tilt control attitude. The somatosensory operation of UAV is the only experience now, which is intuitive. It is much easier to operate than traditional remote control such as American/Japanese hands, and it is easy to get started. After a little practice for 10 minutes, you can take the machine to pierce the ring (the probability of frying chicken depends on talent, I can't guarantee it).
The biggest disadvantage of this product is that it is not delivered randomly, and you have to add 999 yuan to purchase it. Of course, I have no money to buy it. This may be my weakness, not the product.
DJI Goggles V2
Flying glasses are the shape of pilot helmet+alien warrior, and 4 antennas can be disassembled. 420g, about the same weight as normal VR glasses, a little heavy.
Pupillary accommodation
The left side is TF card slot and USB-C port, and the right side is DC power port and advanced 3.5mm headphone port. The glasses have their own fans, and there are heat dissipation/air inlet and outlet grids up and down.
Flying glasses are OK Audience mode , enabling the mobile phone (USB-C port to connect the mobile phone, in DJI fly In the app), watch the real-time image transmission picture, or let other glasses open the audience mode to receive the picture.
The glasses have no built-in power supply, and are connected to the external power supply through the DC to USB-C port. The official power supply can be regarded as a small power bank, which is also connected to the USB-C port, and is also compatible with 11.1 - 25.2 V batteries.
DJI FPV body
DJI FPV machine itself focuses on speed and endurance. It has an inclined design (when flying forward, the body is horizontal). The main body is a bit like its own "Wu" series. The top cover made of translucent materials (chips, circuit boards and fans can be seen below) is equipped with short arms, which makes the operation a bit showy.
The real machine looks small, but the weight of 795g is really important. During the official Q&A, it was mentioned that there are enclosed blade protection accessories, but it seems that they have not been sold yet.
Obstacle avoidance in front and below ToF、 The fill light modules are all concentrated at the junction of the front boom, which also has the USB-C port and TF card slot.
The tilt design makes the DJI FPV in hover look like a fat cat with its buttocks stuck in the sofa.
parts
With the official lens cover, the sense of science fiction is more obvious.
Three blade blade without screw fixing.
The battery has its own feet, with a dead weight of 295g, 44.4Wh, 0.5C when charging, 10C when discharging, and the maximum charging power of 86W. At the same time, the price of 999 yuan for a single tablet is not to be outdone.
Flight and Camera
Gif of flight video

Screenshot 2 of 4K 60FPS original in flight
DJI FPV is a 150 degree ultra wide-angle lens, and the view angle is too large. The image transmission picture can see the entry of blades. The single axis PTZ is equipped with a 150 degree wide-angle lens, and the anti shake effect is actually OK, but after all, there are two less axes, and the picture is a bit like a boat that will swing from side to side. It needs a super anti shake mode similar to a mobile phone to generate a picture with stable horizontal lines.
With 12 million pixel CMOS, 150 degree ultra wide angle+digital cutting, 4K 60FPS video can still be output after cutting (large wide angle and digital anti shake are the natural enemies of discrimination). It was not expected to be high. As a result, the original Mavic mini in the video is still OK, and it even feels like buying FPV machine for free.
Summary
DJI FPV covers the field of transit aircraft in terms of product use, but its selling point is actually the first person flight experience that is extremely easy to master (after all, it is not realistic to fly a plane in person), which will not pose a threat to the existing self assembled transit aircraft, or even boost this field.
It is the mature result of UAV field. Just like luxury cars and sports cars, one pursues comfort and the other pursues driving experience. Individual parameters have no comparability. However, DJI FPV is indeed the most suitable FPV UAV for beginners. If you add money to buy a ride through rocker, it is the FPV UAV that is most suitable for pure white beginners. There is also no one.
