These massed drone formations, what frequencies are they using? Are these just consumer drones or are they set to a regulated part of the spectrum? These massed formations are very noisy. If they are using consumer frequencies I imagine anyone in a nearby penthouse might want to jam them.

In China, both are equally probable.

Okay I don't care if my account gets banned but why in the FUCK does everything about China has to do with the government? Everyone here and on Reddit are bitching about Chinese propaganda bots but the only thing I see is people with new accounts attacking China and an immediate accusation of shilling to anyone who doesn't criticize China or even draws a parallel between whatever is being criticized and the U.S.. Ser…

This is a pretty good example of a propoganda post.

The performance was near a military installation. They probably don't have a licensing scheme in place yet for commercial drone shows.

It's hard to tell from the video but arent they supposed to fail gracefully in a controlled descent and not drop like rocks?

Yeah, kinda points to battery failure, but "our rivals haxxored us!!!" is certainly a nice cover story for the company and the local government.

I'd prefer for the story to be battery failure tbh.

Autorotation? Sorry I don’t know enough about drone aerodynamics, but it’s something seen in helicopters. https://en.wikipedia.org/wiki/Autorotation

Not nearly enough energy in the rotor system of that kind of drone to manage an autorotation landing; and they lack a freewheeling system in any case.

Not sure about these drones, but on my toy drone I can absolutely cut the power and let the wind autorotate the rotors while it falls toward the ground. No need for a freewheel, since the unpowered electric motors spin freely (which isn't necessarily true for a helicopter's engine).

There's no collective so you can't "flare" for landing like a helicopter, but during autorotation the terminal velocity is still much lower than if the blades were fixed.

The drones in this video fall a lot slower though. This looks like controlled descent, not autorotation.

Because it's a trend to bash on the government of China. People don't really care why they're doing something in a trend.

You'd be amazed how powerful propaganda is, and how frequently it is used in all countries across the globe.

Ironically you'll be labelled as a "shill" or "propaganda bot" for questioning the trend. Though it is great to hear when someone does so.

I believe nobody said "evil boogyman". But saying "government controlled" isn't much of a stretch for any Chinese company. I expect they do have some level of "de facto" control on over any company operating in the Mainland

I think that's not a reasonable expectation. Unless you believe that setting regulatory clauses in doing business as "de facto" control. But then so does any business.

Much like every other nation on Earth, the government will seek to take a hand in the largest businesses operating in their jurisdiction.

"Expecting" the Chinese government to control every business in China is very dystopian and baseless. They couldn't do it even if they wanted. The same way my country can't regulate a simple scooter ride-sharing startup during a pandemic...

I wouldn't question China's control over companies like Alibaba. I wouldn't question the US' control over companies like Google. Which again is a totally different ballpark.
