WA smart one would just go home if the uplink was jammed.



That's if the jamming doesn't cause it to crash first. Based on the
videos I've seen of those things, they react very quickly to control
inputs, or lack of.

As Wayne mentioned I suspect that if the RC craze continues and more
incidents of "spying" in a neighbor's back yard occur some restrictions
will be legislated on their use. It's one thing for Google to be
taking static satellite photos augmented with aircraft/helicopter images
to generate maps of the entire world. But a "hobbyist" purposely
targeting someone's backyard or house from 200 feet and video recording
the "visit" is another thing altogether, plus the annoyance of having it
and it's noise hovering in your yard. Given the lack of federal (FAA)
regulations and state regulations many towns have already enacted
ordinances governing their use. It's common sense.

It might be illegal to down one by shooting it but who's going to prove
you jammed it?



It just depends on how smart the drone is. If it has a processor and a
GPS on board, it will default to going home if it loses the up link.

These things are really pretty quiet. If you didn't look up, you might
not even know it was up there unless it was very low.

Many of them have GPS on board.

Those things are more powerful than you think. They mount some pretty heavy cameras to them on
gimbal mounts. Even that little one of mine is powerful enough to carry a camera.

This one uses those expensive homemade floats (plastic water bottles), and seems to do quite well.

Sharp steel rotor blades would damage the other aircraft, but would also be damaged by the impact.
Plus, if one came flying off while powering up, you could lose your head! The design of the blades
on my 'copter allow for strikes against walls, ceilings, furniture, etc, without damage to either.

Pointing a laser at an aircraft is specifically illegal. The law is
written broadly enough that it probably applies to a drone

you arrested is within 1000 feet of a school. You can get suspended

The annoying kiddie copter will have to be flying damned low to be shot

I got one of these for the Sig. Don't think it would do much damage to an RC quadcopter though.
