You can't take control, but if you "shoot" it with an antidrone gun you can block the controller signal and also have the option to block the GPS, and it will simply hover and try to land as the battery drains out.
You can also release the GPS blocking to allow it to start the RTH so it will fly to the takeoff location while you maintain the 2.4/5.8Ghz jamming, and then block the GPS again to make it land, that's the only way to “control it”.
GPS spoofing is also a thing, but police just use the jammers.
If you have the
M3 hacked, you can set it to escape antidrone guns. It won't hover in place when the signal is lost, it'll rise to a predetermined altitude where you'll have more chances to regain control, as antidrone guns need to be around 5 times closer than the controller to have any effect.
On the other hand, that's what happens when you have the drone registered, they check the number on the database and then go to your home, and if you are naive enough, you'll confess in the act without even a trial or a proper defense.
Hobbyist don't tend to realize that we are just considered terrorist/chinese spies and think that by complying with the rules and bureaucracy and not paying attention to what rules are actually infringing, they'll be safe; while it's the total opposite.
You need to comply with the basic paperwork, but be completely aware of what you are infringing or not at every moment, and have some failsafes in case s**t happens; else, prepare your ****.
If he hadn't registered the drone, he'd just lost an
M3 and a battery, now he'll have to pay the fine for doing absolutely nothing but flying a drone.
