Hope this happens everywhere...



No you don't, dumb****. What happened to the eagle (if that's what it was). Those
propellers will easily take off a finger, let alone cut up an eagle, or hawk or any
other bird, very badly. You'll note the drone is still transmitting, which means the
owner can easily retrieve and repair it.

No one knows what happened to the bird. I hope it made it.

And I hope you learned something.

Myth busters tested drones. All but the biggest were pretty much
harmless. Some of the big commercial ones with carbon fiber blades can
leave a mark ;-)

I've seen the damage a plastic airplane propeller going at a much slower rpm can do
to a leather covered ottoman corner. Ate right through it to the stuffing. My wife
was very unhappy. I'm thinking your 'myth busters' test is bull****. Although small
and plastic, those props are going several thousand rpm, and they're very sharp.

Here's a view of some of the damage caused with the airplane/drone that caused the
problem, in some cases. It's in French, but you get the idea. Imagine if those cuts
were in an eagle's neck? Or a foot joint?

Dunno. They were using a few different small hobby drones hitting a
ballistic gel dummy and watching it on a high speed camera.

This really comes down to this being a very light propeller driven by
a pretty weak motor. You can't compare that to the old 2 stroke model
airplanes.



Based on what I've read (and heard), the lithium/ion batteries used in
these hobbyist quads are more dangerous than the spinning propellers.

I imagine it is just a matter of time until these things outgrow the
batteries and they put a fuel cell or an IC engine in them to increase
range. Then you will have some serious danger.



I've seen pictures of a lithium/ion battery in a carrying case that
"let go" during a recharge. Caught fire and damn near burned up the
owner's SUV that it was in.


A lot of folks store them in metal ammo cans or something like this:
