Drones for local sounding...

Does anyone use a drone for local sounding ?
What kind of drone ? Where can I buy one ?
Maximum altitude achieved ?
Thanks in advance -

In the USA, the FAA has a voluntary standard for model aircraft that limits operation to 400 feet AGL.

The new legislation for UAVs picks up that 400 AGL limit as I recall.

That said, there are pirates flying quadcopters much higher (7000 meters?). Search Youtube for 'quadcopter altitude record'.

There is also guidance for flying "RC aircraft" as a hobbiest within 3 miles of an airport. It can be done with proper precautions.
Can you see the RC or quad copter from 6000 to 8000 ft away safely to operate it?

Actually the FAA has no specific height limit for model aircraft. The Academy of Model Aeronautics (governing and insuring body for model competitions) has a safety rule that limits altitude to 400 feet within 2 miles of an airport, but allows other altitudes elsewhere and also with permission of the airport operator. Many of the model sailplanes are operating at altitudes above 3000 AGL when participating in XC contests, they are required to have a specific observer looking for full-sized aircraft to avoid collision.

If a model is being flow outside of a contest, and not by a member of the AMA, then all bets are off!

That said, the FAA does advise in ac91-57:

"Do not fly model aircraft higher than 400 feet above the surface."

Using the argument that they are not aircraft and that they are therefore NOT under FAA jurisdiction, some UAV operators are asserting their rights to fly their aircraft in Class B airspace.

I did not see anything in the article related to Class B airspace.

Hmmm .... a drone in class B airspace? Wait until one of them gets sucked through an engine or leaves a long lasting impression in the nose of a jet. I am always shocked by what stupid things people do just because they can and because there are no rules saying you can't do it. The same bunch of guys then cries wolf for 'government over-reach' or 'over-regulation', if everything gets regulated. Common sense seems to have vanished!

Right, I posted that particular article because it seemed of marginally better quality than this more highly editorialized article that mentions Class B http://motherboard.vice.com/read/the...ies-is-a-crime

The Class B in question is the surface to 10000 AGL bottom layer of the upside down layer cake.

Here is another case that is trying to stretch existing regulations to cover UAVs. Of note is the 'You're not my boss, so don't tell me what to do.' rabble-rousing tone that reflects poorly on the UAV community.

http://www.forbes.com/sites/gregorym...on-their-side/

The UAV hobbyists communities are in general doing some really exciting things http://www.meetup.com/DC-Area-Drone-User-Group/

While I agree that common sense is definitely on the decline, common sense
would eliminate the upsidedown wedding cake and regulate only the arrival
and departure routes. What mad man actually believes that all of the
airspace in a Class B area is actually required for safe airline operation?

Stupidity is in the eye of the beholder and not necessarily fact. Tell the
airshow pilot that an inverted, low level ribbon cut is "stupid". I'm only
arguing for intelligent regulation of airspace in place of the standard 30
nm around a busy airport.

And, yes, I don't think it's wise to poke the bear by violating the rules of
"good sense".
