There was a problem in California fires last year..."If you Fly, We Cannot Says Firefighters".
Actually they can deliver things like small bombs and grenades pretty effectively. That's why the government wants to know and should know about everyone that has the larger capacity ones.
This is an awesome application of fixed-wing drones to deliver medical supplies in remote areas:quadcopters have shit payload capacity. and compared to a fixxed wing air craft crappy range as well.
If your going to do anything commercial there are new regs that must be followed.
I got a little one for Christmas. Got some spare batteries for it then wrecked it within about twenty minutes of having a stack of batteries charged and ready to rock. I came to the conclusion that the small ones suck if there is any wind to speak of where you are trying to fly them. Big ones are way better but also require FCC registration, FAA for really big ones I believe.
A bought a replacement copter so I have a working set again.. didn't have to buy the whole set, old radio works with new copter.. but haven't gone back out since testing out the new one to make sure it works. I'd love to have access to a big gymnasium or other large indoor venue to fly the little one I have. Outdoors they just get knocked around too much when the weather isn't ideal.
I suggest you clean off your screen before you watch this video, I found myself following a speck of dirt for about 15 seconds.I really need to get a DVR set up so I can record my video feed.
this my newest micro build and by far my fastest. I am also flying with only the gyro now, and no auto level.
