DJI seems to be the one company that requires sideloading the Android app. DJI makes great products, but there's really few companies who I would trust less to give unvetted access to my phone. I know the Android app sandboxing should help a lot, but there's enough unknowns & potentially lurking security holes that I really wouldn't want to trust them. They also are 100% the most likely company on the planet to self-…

Pretty sure this comes with it's own standalone DJI remote (which is really just running android underneath). No need to sideload or connect to your phone in any way.

I'll probably keep my Mini 2 until someone has the semi-legal cojones to put a 4G transceiver in a drone. Now that would be some great fun.

Why? The range is like 9 miles so it is hard to get the device out of range of the radio on the battery charge.

Not on consumer DJI drones, especially if you live in an area with a lot of trees. I get about a mile on average.

Ukrainians need this for their counteroffencive. They name Mavic 2 as their favourite drone.

is the primary use of drones in the Ukraine war for recon? I know they're also using them to drop grenades and fly into targets. I'm sure every military in the world is watching drone use very carefully. An FPV flying RPG warhead in a dense urban environment sounds like an absolute nightmare to defend against.

Pretty sure competent militaries have much better jamming systems than what we're (not) seeing in Ukraine.

Earlier quoted context omitted.

It does a similar sort of thing - asymmetric offset propellors shunt the frequency of what gets emitted way down. It still emits a similar amount of energy, but the direction of emission changes, and with the lower frequency, there's a lower perceived sound. Toroidal props actually have less sound coming off them, and at a lower frequency. I've got some ideas about how you'd potentially then have a greater spread of…

>I can get really boring on applications of acoustic design I found that fascinating. TIL about the car tire noise. I think you've got the right kind of audience here.

Agree, GP there is an an audience for your pontificating, if you ever feel like it.

Simple: don't use your phone. They make remotes that have screens built in.

No way I give them access. I even have them connect to a locked down SSID in my house LAN.

When will these compact drones become less noisy? I know there are new propeller designs being researched to be much less like a swarm of bees is flying around near you, but don't know how far off they are to retail commercialization. It just makes it hard to stomach flying a drone in a pristine environment knowing you are disturbing all human and non-human animals nearby.

Are they really that noisy? I fly 10" drones and once they are about 30 ft away you can't really hear them. 3" and 5" drones are silent at 30ft on a calm day.

Does anyone have an authoritative source on what data DJI captures and relays to China?. I want to buy a drone but concerned about privacy.

There have been some audits including the full network capture with Wireshark https://www.precisionhawk.com/hubfs/Retest_DJI%20Cybersecuri... https://www.auvsi.org/sites/default/files/DHS%20report.pdf This is from the DOI, see from page 40 https://web.archive.org/web/20190916135227/https://www.doi.g... >We did not detect any leakage of data to DJI servers with any of the apps. However, all three apps make a Domain Na…

Note that the CCP can command a device to phone home in the future. So "We did not detect any leakage of data to DJI servers" just means that the device is currently not sending data home.

>Freedom enables choice. One could argue that also for the freedom to choose a curated platform. Android exists and prospers, I have a choice.

What happens when Android starts clamping down, as they have? Android ever more ratchets shit down, and more and more essential apps like Termux simply can't make it through the Google gauntlet. What happens if Android stops allowing sideloading? I hear this defense a lot from the anti-sideloaders, that it's fine that this platform have no freedom, because there's another popular platform with some freedom. Even with…

It hasn’t yet, but if they do there are already alternatives in the Android world. That might the chance that Microsoft, Amazon, Epic, or any other company might take to launch a phone that allows sideloading.

You don't need a phone to activate a new DJI drone?

Every device manufacturer tends to fib a bit on battery life vs. real world, however, 45 mins of flight time is impressive. Even if its 30-35 mins fully maxed out that can give you a lot of time to creat content and explore

Tangentially: I wonder if a really long-flying quad copter can be made using a regular ICE + generator as a source of electricity. Carbohydrates are still more energy-dense.

It has been done, you can buy Chinese made very light 2 stroke engines packaged with a generator. Used for large hexes and octocopters. Incredibly noisy and the lightweight design of the engine means it has a very short time in hours operating before rebuild.

These are a known thing from like three or four different vendors in the community of people who build medium to large sized ardupilot/arducopter based things.
