From 2020, how do you say copy in Chinese? It shouldn't be too hard for them to make, if they show up in Ukraine with Russia firing them, there would be trouble. These might look like the real thing, but inside they could be just made from common RC plane parts and might be easy to knock out with electronic systems. I'm sure we would love to have a close look at one, under the right circumstances! Not a head on view as the last thing ya see...
They so make those DJI drones, so they can build quality and do electronics very well the chips that run these things are the same ones used in Arduino small computers ARM STM32 microcontrollers or something more powerful, like that used in a Raspberry Pie.
