I always look at these and think I want one but also can't think of what i'd actually use it for. I just picture it sitting in a closet next to my GoPro and Oculus after about 3 days of messing around. Anyone own one? What do you use it for?

I bought a Mini 2 about two years ago while arguing with my insurance about storm damage and roof repairs. Close up, high quality, multi-angle stills and video made it a lot harder for them to argue that their inspectors had done a good job. Their inspectors had, in fact, done a shit job, but it was my word against theirs until I had video proof of my claims. Paid for itself many times over.

Perhaps but I fly my Mini 2 regularly, and people have a hard time finding it in the sky even when I point it out to them at 100ft. At 200ft it might as well not exist. They are so small and light, they just don't put out the dBs like bigger drones.

Being able to spot a small white object in the sky and hearing it are very different things. I put drone operators on the same level as those who hike with speakers blaring. No one is being hurt, no laws being broken. Just inconsiderate considering a large part of the experience for most in nature is the serenity.

>Being able to spot a small white object in the sky and hearing it are very different things.

They are but not the way you suggest, you stop hearing it long before you stop seeing it. :)

Streaming 1080p/60fps up to 20km wirelessly is mind boggling to me. What kind of tech is used to make that happen? seems like it'd require a lot of power.

DJI OcuSync is based on LTE: https://www.suasnews.com/2022/05/the-dji-p1-and-s1-fpv-chips... is an example of more information. This is a major advantage DJI and other Chinese drone makers have over US based ones. Technically acquiring an SDR/DSP implemented LTE baseband is not a major difficulty. Getting Qualcomm to let you is quite a challenge. Looking at FCC listings and product pages you can tell that DJI are als…

Is it using LTE bands? Or just LTE technology on non-licensed bands?

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'd like to find a good competitor too, and not just because of the geofencing. DJI has been identified as a national security threat by the US DOD, essentially because there's no way to be sure that every second of GPS-tagged video shot by a DJI drone isn't going into a giant server farm owned by the Chinese intelligence service. https://www.defense.gov/News/Releases/Release/Article/270608...

Also a national security threat because they're game changing weapons and they make the most and best of them.

Beware that DJI's software to control these craft is super sketchy to install and use. It doesn't exist in the Google Play Store, to avoid inspection.

I thought that was because the company was sanctioned by the US, and therefore google can't work with them?

Do you have a recommendation of a drone with similar features that doesn't require jailbreaking?

I've heard good things about Skydio.

They have discontinued their consumer products sadly: https://www.skydio.com/blog/skydio-to-sunset-consumer-drone-...

DJI is fully compliant with China's policy of civil-military fusion. Anyone flying anywhere sensitive should not use them. They're beaming back home whatever they want, and China is using both tech and data to give an asymmetric advantage to allies like Russia in the Ukraine war.

>They're beaming back home whatever they want

This claim is always thrown out like a life preserver without ever anything to back it up. Do you have anything to support this claim?

But yet it exists on the Apple App store where I am sure Apple has inspected it. I guess the Android version could be a lot different, but why?

I'm not sure if you're joking. Apple's business depends on them bending the rules for China.

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.

Recently a Russian commander got killed because he shared his daily running route on Strava which was seen by the killer.

How do Ukrainian operators avoid exposing their own positions? Do they install custom firmware on their drone?
