"That's right, your GOD given rights trump the safety of thousands of people.
In 1988 an 8 year old girl was exercising her right to fly a kite at a local park in Palo Alto. It was in the landing path of the airport. It was also a 12 foot kite with…"

""A lithium-titanate battery is a modified lithium-ion battery that uses lithium-titanate nanocrystals on the surface of its anode instead of carbon. This gives the anode a surface area of about 100 square meters per gram, compared with 3 square…"
"Hmm . . . The micro turbine in a hummingbird. Don't ya think the sound might give it away? :)"
It's a Nano Hummingbird!Nano HummingbirdLos Angles Times StoryAerovironment has been working on this since 2006. Under a $4 million contract from Darpa they have a hummingbird drone that weighs 19 grams, flies 11 mph, can hover, fly forwards,…
"Electronic retailers have the same problem. They sell established, finished, tested consumer goods. TV's, computers, phones, you name it. And they still get returns from people that just didn't read the manual. That's not to say there aren't…"
"I would guess that most of the people that bought an RC have no idea what the rules are. Most take them to a park and have a nice day at low speed and altitude.

"Cool toy.
The closer everything is to the center of mass the easier it is to turn. You are trying to pivot a lot of mass with the ducted fans alone. I would move the boards, the ESC's and the battery to the center.
You are pushing a huge amount…"

Well, sort of. The only thing I see in the code turns on OUT7 when the motors are armed.
//#define IsAM // Do we have motormount LED's. AM = Atraction Mode
if (motorArmed == 1) { #ifdef IsAM …"

"Less than ten years ago this flight makes you realize how far we have come. Now you can buy the electronics here ready to fly. If you feel like flying across the Atlantic, you might want to read this first.

"Having a law and enforcing it are two different things. CB radios ALL were required to have a license and pay a fee in the 1970's. Nobody did. Ham radio requires a license. Not enforced.

"I think you can interpret the frame material "Fused Deposition Modeling" as "Unobtainium"."
"The mass and center of gravity of the system do not change and that is the largest factor in the PID settings. If you were burning off fuel and the fuel tank was not near the center of gravity you could change PID settings.

""If you're on a tight deadline, this not the project for you! It's in development and probably will not be in full feature release for a month or more. It's in beta now."
