I've got the Mavic 3, and while it's an awesome piece of Hardware all around, I am royally fucking pissed about DJI retracting on their promise to release an SDK for them, which stops me from using litchi with it.

Light drones are great, but how far away are we from quiet consumer drones? I'd love to not have every hike ruined by some wannabe videographer.

The mini is pretty damn quiet. At 50ft of altitude people don't hear it. AT 100ft of altitude people don't even see it. I've flown one hundreds of times and other than other drone owners no one has ever said a thing or noticed. The drone owners notice and come over to talk drones.

I have noticed that it really depends on the wind direction. If the wind blows from the drone towards the people, you could hear it at 50 meters. Plus, when there is a lot of wind it makes much more noise in its struggle to fight it. Otherwise, unless it is directly next to you, you can hardly hear anything.

My biggest crowd are children and pets. They always seem to be amused by the drone.

Makes enough sense to me but curious why specifically? Are they quieter or less dangerous below that size / weight?

> Are they quieter or less dangerous below that size / weight? F = m*v^2

>F = mv^2*

F is some number of joules equal to twice E_k?

Lots of people avoid confrontation

I got all excited thinking of the potential of keeping this at the bottom of someone's pack given it's low weight, until I remembered how much I despise people flying drones on top of my head whenever I'm out in the outdoors, looking for a peaceful place to connect with nature.

Yeah this. In the middle of bloody nowhere in Central Asia completely off any beaten track and there was wanker with a drone buzzing around.

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.

Transmitting long distances lives on a kind of spectrum. On the one end you have MOAR PWER and on the other end you have signals analysis and robust codecs (? I'm not sure "codec" is right. Maybe encoding? Can someone answer this?) that allow for lost information. The signals analysis will clean the incoming signal and the codec/encoding will allow for robust recreation of the captured data.

Most wireless transmission technology lives somewhere in-between the extremes of the above spectrum. Signals analysis is quite advanced and codecs/encodings are also quite advanced at this point.

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 have a friend that builds his own drones (and RC vehicles, like a really big, fast tank). He sneers at DJI, but keeps one to entertain the mensch (that's me). He also sneers at licensing, jailbreaking, geofencing, etc. I notice that there aren't any pictures that actually show people in close proximity to the drone. The "drone in hand" picture looks photoshopped, so I assume the drone is actually not-so-mini. I hav…

The others do not say a thing because they are polite probably :)

I got a proper bollocking when checking out some newly built houses with my drone, one of which I was thinking about buying. The lady thought I was trying to film her garden, probably warranted since I took off not far from her residential house. I've learned to stay further away from people while flying since, which the rules dictate anyway.

First off, those numbers are a huge asterisk for perfect atmospheric conditions.

In reality you will see about a 2km max in relatively clear conditions, and as few as half a km in even normal suburban/urban conditions.
