Hold one or the other controller upside down. :-)



Or reverse that controller. Many have a switch for that.

My neighbor Henc is always bugging me to buy a little drone but I am
still not sure what I would do with it. It looks like something I
would play with a few times and then put it away. It might be
interesting to explore the mangroves that you can't walk into but if
the drone went down, you would have to I suppose.


I have an indoor copter. IR link. Grandkids like it. Was about $10.

We had one around here a while and the kids got tired of it pretty

I think it may have died after a dunk in the pool tho. Nobody said
they wanted a new one.

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?

http://chrismeme11.over-blog.com/article-36258812.html

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.


Many are the lighter Lithium Polymer now which is supposed to be safer.

Supposed to be but lithium is lithium and it reacts violently to water
vapor ... just the humidity in the air can set it off. The safety
factor is in the packaging it's contained in. If it is compromised, you
have a problem.

I visited a lithium battery manufacturing plant once. The assembly was
done in a clean room where the humidity was maintained at 5 percent or
less. As we were putting on our "monkey" suits in the lock before
entering the guy I was with warned me about how hard it would be to
breath when we entered the clean room. He wasn't kidding. When we
entered I gasped for air at first. 5 percent humidity is extremely
uncomfortable.

Interesting. The humidity in an airplane at altitude is also very low
and every seat has at least one lithium battery in their possession. I
wonder who, if anyone, regulates the packaging. Some lithium batteries
I have seen are in a very soft-sided package - almost like a ketchup
packet.

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



http://www.discovery.com/tv-shows/my...s-kill-people/

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.

http://i98.photobucket.com/albums/l2...1/P1010681.jpg

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.

Most likely. Setting up a transmitter is complex as hell.

All of my lithium polymer batteries are 'soft sided'. They can expand and contract,

when severely discharged. Luckily I was able to salvage it following a tip in a
forum.
