Even if they are 10x more quiet, then if there are 10 of these drones flying around we're back at square one.

Both fortunately and unfortunately that's not how sound works. If the drones are far enough away from each other that you don't get interference between them soundwise it doesn't matter if there are more of them. But if they do then two quiet ones may re-inforce to the point that they sound much worse than a single larger one.

Are you saying that sound conduction doesn't behave linearly?

For the infrastructure, for legit strategic reasons (without even considering they are abusing it, you generally don't want to rely on foreign infrastructure on your territory). For the smartphones, that's pure commercial war. Huawei was a big competitor.

Huawei was on a trajectory to become the biggest smartphone vendor in the world, when they were kneecapped in 2019, mostly by blocking their access to Google services (which cratered their sales outside of China).

They're cloud based, aren't they? So regardless of what they're doing with the data, it's true that they're (figuratively) beaming it back, although parent is admittedly implying more. I accept that chinese authorities generally have access to anything they want to in the country, so I would buy that they have access to drone data.

So just like the US ?

US vendors slept on 5G, and Huawei prepared end-to-end gear, from backend systems through antennas to handsets. This resulted in Huawei getting a lot more deployment in 5G, and triggered less than open retaliation. The handsets themselves were minor issue compared to possibility of China eating US' lunch on 5G.

I've had the original Mini since it came out. Other than damaging a prop from it hitting a blade of grass on landing it is in perfect shape. Yes, they are so fragile I landed very smoothly in the grass and soft grass is enough to damage the props! I don't fly it as much as I used to. These new ones are certainly an engineering marvel with how much they have added and still kept it under 249g. The big one to me though…

I think it's a good thing the props are fragile as the motor would be damaged if the props hit an object without absorbing the force of impact.

haha, check out freestyle fpv. you won't believe what the motors can survive.

nope. the US doesn't have the same military-civilian fusion that China has, given the latter is an authoritarian one party state.

You do not need to transmit the video first. But coordinate or interested person. Even a sport watch can be a security threat as demo by some exercise army personnel. They just know who and when and where these places are. For the transfer part it is much harder as said and easier to detect in peace time. But then what happen in war or proxy-war time. You have to know how many senior Russians are killed by using a ph…

> Even a sport watch can be a security threat as demo by some exercise army personnel. In the early days of the Afghan (or was it Iraq?) war, people used Strava to figure out the locations of American bases. They'd see a bunch of smart watches suddenly wake up in the morning and start exercising at the same time, a dead giveaway.

I believe the incident you’re referring to happened in 2018 [1].

Also happened across a few American bases across Syria, Yemen, Niger, Afghanistan, Djibouti and more. Some British and Russian bases were highlighted too.

I have DJI drone. It's very easy to fly, however there are all sorts of restrictions that exist in the software which are not in sync with local laws (which may be more liberal than what the software thinks), so your only option is to use sketchy means to actually use the drone.
