Allegedly an accurate model of Z-20 from AVIC itself, according to Weibo user DS北风. Note the AVIC logo on the base of the pedestal.

All official AVIC models like those are very accurate to the real thing. This is because the model maker is part of AVIC and have access to the design drawings. They usually give them out to VIPs and staff that work there as gift. In the lobby of the CAC hotel in chengdu they have a display section with probably 20 models on display (I'll see if I can dig up my photo sometime).

I'm just surprised they have a z20 made already since the plane is not declassified yet. I only got my J10A model 2 years after J10B came out. JF17A I got pretty much right away since it was never classified to begin with. Maybe same situation with z20.

Very nice model.

Regarding the surprise, I think we should differentiate the Chinese "secrecy practice" with western counterpart. In China the boundary of guilty of leaking unauthorized information is not a clear cut compared with the west.

In the west, once something is declassified everyone has the right to access and spread such information, before that access would be limited to authorized person who has a documented clearance level.

In China, the staff in the program may talk about it with their Children (who apparently don't have the clearance) or give a model as a gift, both the staff and the children would then be responsible to keep the secret. If nothing leaked to the forbidden audience everything is fine. But if it does get into the ears of the forbidden audience, both the staff and the children will be guilty for punishment. Except the government official revelation, any revealing by anybody else is punishable if the government deems it damaging even if the program or product is decades old. In other words, there is never a (Chinese) declassification in the western sense.

The principle in China is that, the responsibility of keeping state secrecy rest on every citizen, not only on the people in the program, nor is there a codified boundary. As usually goes, don't ask if one is not supposed to ask, don't say if not supposed to say, one see something keep it to oneself, otherwise the person is guilty of anything and everything.

Same as J-20, it was photographed in broad day light by many wall climbers. Nobody is punished for leaking. But once the government build the higher wall and told everyone to stop photographing, it becomes punishable, same act, different treatment, not because of classification regulation but because of government decree.

Not recent but decent article on Z 20 See like they are undergoing acceptance test now It could last a year maybe. From AIN Online. They do need medium size Helicopter for both army and navy Specially navy which is handicapped by small helicopter that can carry only limited suite of ASW equipment

China Has High Hopes For Z-20 Helicopter

. It made its first public appearance at the 2016 Zhuhai Airshow.

At first look, the Z-20 bears a strong resemblance to the Sikorsky UH-60/S-70 Black Hawk series. It is commonly referred to as the Chinese Black Hawk. However, Z-20 designer Deng Jinghui told Chinese media that the Z-20 is a fly-by-wire design. Key visual differences are five main rotor blades on the Z-20, and more angular tail–to-fuselage joint frame. Military observer Huo Yanbin thinks that these features will give the Z-20 more lift and greater cabin capacity and endurance than the Black Hawk.

The most recent photos also show a new fairing installed aft of the engine exhausts and another on the tail spine, which are likely housings for satellite communications or the BeiDou (Big Dipper) satellite navigation system.

A crucial part of a successful development of the Z-20 would be the integration of its engines. It is widely believed that the primary powerplant for the Z-20 is the domestic WZ-10 turboshaft engine, providing 1,600 kW (about 2,145 shp). In comparison, the latest UH-60 GE T700-701D engines produce 1,500 kW (about 2,011 shp).

Beyond highland operations, Huo thinks the Z-20 will be a key air mobility and projection platform for the PLA, and will also provide the People’s Liberation Army Navy (PLAN) with a much-needed multi-role naval helicopter. Huo says that compared to the Harbin Z-8/18 series, the smaller size of the Z-20 and its newer systems will enable the Z-20 to be interoperable across all PLAN ships, yet large enough to install a full suite of anti-submarine capabilities. These are not found in the navy’s current Harbin Z-9 and Kamov Ka-28 helicopters.
