What part of the spray type drones is the FCC and the US Govt actually concerned with? I would assume it's the receiver/xmitter sytem of the drone that actually communicates with the remote controller?

If so, I wonder if anyone is exploring "gutting" the drones in question and replacing those comm devices with "approved" devices made somewhere other than in China?

Finally, consider Ukraine's use of the common DJI drones that are sold commercially in the U.S. UA is using them in a war against Russia, and successfully. It seems if China really could or does use transmitted info from drones they would certainly apply it to their friends in Russia and make the UA use of them worthless. But, that doesn't seem to be the case.

I have always suspected we're worrying about nothing.
