One another thing which comes to my mind when thinking about "gamechanger" cheap FPV drones -> I think this is the first weapon in the history of warfare where lion-share of development was done via voluntary collaborative effort (aka Open-source software development).

Because those drone are not "developed" by Ukrainian companies, American companies, or even Chinese companies.

Of course for example UA companies/orgs do a lot of work but it's a bit like saying your local car performance tuner (who tunes engine ECU maps, adjusts suspension, etc.) "develops" racing cars.

Game changer innovations which enable the concept -> very maneuverable, rugged, reasonable reliable and ultra-cheap way to precisely deliver payload over considerable distance are following:

* FC Firmware -> what started as a toy project experimenting with first affordable gyro/acc board from nintendo game controllers (Wii console) morphed into cutting-edge firmware for racing drones (Betaflight), where big community of contributors is striving to achieve maximum performance for drone racing, basically translating every stick input from controller to solid, exact response of the flying craft.

This piece of puzzle is a key to enabling Multi-rotor control, whether remote or autonomous (AI guided), without working FC firmware, it wouldn't be possible to control multi-copter at all, even in manual mode.

* ESC Control firmware -> piece of code which generates control impulses for brushless electric motors. Those motors are almost comically primitive pieces, essentially couple of coils, magnets and 2 bearings... No valves, no linkages, no delicate parts at all. Without ESC firmware energizing the coils in exactly the right moment, it's a dead-weight not capable of doing anything, you can't just "connect it to power source", you absolutely need ESC running dedicated firmware.

Top ESC firmwares like bluejay or AM32 are again open-source collaborative efforts.

* RC Control link -> this used to be proprietary piece of hw/sw controlled by RC model companies (Futaba, Spektrum...), but amazing piece of open-source software called ExpressLRS changed all that.

Now we have a open-source radio-link which you can customize to operate on almost any frequency you want to, it's much longer ranged, cheaper and more efficient then closed-source proprietary offerings before it.

By the way each of those projects started before dedicated hardware was available (like I wrote, first practical community FC for multirotors used board from the Wii gaming console) and only after their success created community demand and market, (mostly Chinese) companies stepped in and started producing more dedicated hardware (cheaper, smaller, better performing...).

Almost none of the people working on those technologies are doing it for military purposes and they are quite hostile to any feature requests linked to military use (most of those are stupid btw, like demanding inertial navigation capabilities from firmware running on $40 control board...) and I can't blame them to be honest.

Not only that. This emphasis on 'real soldiers' is entirely obsolete. As an army you need gamer boys and girls for your drone teams. The anti diversity mentality is harmful. By the way, this investment in the F-35, was it really necessary? And what if buyers start to pull out of the program because they consider the US as not reliable and trustworthy anymore? The US defence system is in deep trouble.
