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.

Wrong. Do some research on these 'weak' little motors.

Well, I suppose all the cuts in the article I cited could have been fake. I know this
was caused by a plastic propeller on an electric motor.

Yes, they were using small drones, with small motors and very flimsy propellers. Not
all drones are small, not all have very small motors, and not all have very flimsy
propellers. The flimsy propellers will not stand up to a decent breeze.

As to a comparison between gas and electric:


"With the changes in rc electric motor technology it is possible to fly ANY size
model using rc plane electric motors. The biggest leap in making this possible has
been two fold. First we have model airplane electric engines that are powerful
enough, not to mention much more efficient, that they rival or even surpass
gas/slimers/smokers/nitro hogs, or whatever else you may call rc airplane gas
engines."

"Example: Hangar 9 Arrow with a .40 size gas engine would require an electric rc
motor equivalent to an AXI 2826/12 External Rotor Brushless. "
[from: http://www.rcmb.org/Electric_Info/glow_elec_bonus4.pdf]

What is an AXI 2826?12 External Rotor Brushless?

http://www.hobbyexpress.com/brushless_axi2826.htm

Note the specs: Motor Diameter 1 3/8"

And I'm sure you'll recall the .40 gasser was a decent sized engine with a propeller
that could do some serious damage.

Yup, you're probably right that the drone might not be as bad as a load of buckshot.
Might not cut through all those feathers. But then again, it just might catch the
bird in the neck, in an eye, or on a wing tip.

In any case, wishing more eagles would attack drones is, IMHO, pretty friggin'
stupid.

OK you win, they are flying death machines but I think I would keep it
to myself if you like flying them ;-)

We're flying machines that could hurt a bird (or a human for that matter)!
