Is it really a lot for an RC hobbyist? The only RC hobbyist I've personally met had a whole garage filled (as in no room for an actual car in said garage because even the middle had more tables of it to fit planes and tools that wouldn't go on the walls) with stuff like this. That's a sample size of one of course but I didn't get the impression from him talking about his stuff and about his RC plane buddies that he felt that he had an unusually large amount for someone really into that hobby.

And a lot of that can absolutely be used for intelligence work.

I mean, probably, but by the same token, so can binoculars, a smartphone with a camera, a camera with a telephoto lens, a radio, and a ton of other stuff that lots of people will have.

And if you're trying to spy, (a) you don't need a large number of drones

that's important if you're using them as disposable weapons

and (b) my guess is that most of those tiny, short-range ones would be of pretty limited value in most cases.

EDIT: I'd also add that my guess is that one thing that Ukraine is probably not terribly short of is abovehead intelligence. As Mike Kofman pointed out repeatedly, the military value of the intelligence that the US provided to Ukraine is probably greater than the weapons. They've got satellites and a bunch of other sensor platforms. And the US isn't the only one providing intelligence. And Ukraine can already fly drones

albeit perhaps more-expensive, longer-range ones

over Crimea out of unoccupied territory. That's not to say that there isn't still utility to drones

I mean, maybe flying one into a warehouse with an open door is safer than going in person. But by-and-large, my bet is that the most useful intelligence Ukraine gets from people behind the lines isn't aerial photography.

Not that much, and absolute majority of it really can't be used for intelligence work, fpv cameras are trash, as in you can't see anything fron afar and when you aren't far you can hear them very well. (yes digital cameras exist, but they aren't all that great and can't be compared to dji) Also almost everything showed is a hobbyist grade things, either too old, or almost useless for any real work.

You have a brain. Can be used for intelligence work, but nah you decided to fall for russsian propaganda.

And Ukraine has made it pretty difficult to tell the difference lately.

AFU using lightweight recreational aircraft as bombers

Still, fuck Russia.

Can hardly blame them for this considering we've outright killed Iraqis for carrying "bomb-making material" (scrap wiring and PCBs).
