They wouldn't want to use a firearm for that. Might get guns banned...

I hope not, i'm pretty involved in the high power rocketry hobby and the materials/electronics and knowledge exist in the hobby to make something like a guided surface-to-surface rocket with a range in 10s of miles but no one does because it would instantly ruin the hobby for everyone. A friend of mine in heavy into r/c planes and is an embedded engineer so he has a bunch of autopilot stuff going on. I'm sure he can scale as high as he wants (he's also a private pilot) and fly a heavy payload to a point on a map autonomously. Again, no one does it because it would ruin the hobby for everyone.

Lots of people want to do this but the place for it is like a DARPA challenge not in the general hobby. If the authorities got wind of it then down come the regulations and no more hobby.

Yes, as a long-time fixed-wing RC hobbyist, it's generally the newbie idiots who do stupid things that threaten the entire hobby. Despite all the new rules (which I don't even bother to keep up with anymore), I still fly my planes like I always have. And just like always, I don't bother anyone and no one bothers me.

The problem for drones is easily weaponizable models exist off the shelf for people with malicious intentions and no interest in preserving the hobby. To weaponized a rocket requires more intellectual investment.

Hey at least if the drones are turned into weapons there's a chance the Supreme Court might overturn the bans.
