The FAA has been issuing alot of COA’s or certificates of autorization to fly uav’s there is an ok article on the topic at http://www.cuaf.net/Media/FAA/UASS.html it covers a little about the coa

We've got a whole site on DIY Drones (at http://diydrones.com, of course), including on the FAA regs (many of the above comments are confused).

Basically, for non-commercial/recreational use you need to stay below 400ft, line of sight, pilot in control (meaning you can take over at any time), away from populated areas. For commercial use you need a COA. The FAA is working on some future rules that will establish a special category under 4lbs, but I doubt that the rules above will change much.

There was a DIY UAV segment on Wired Science a few weeks ago that was pretty cool

RC airplanes are ok because they are controlled by a pilot from the ground. But the moment you build a flying vehicle capable of guiding itself to a fixed location (i.e. guidance system, autopilot etc), it becomes illegal (or if not outright illegal, something that the feds are going to want to look further into anyway). Doesn’t matter if its got a rocket engine, jet engine, propeller, rotor blades, warp drive or whatever, its the fact that it can fly without someone on the ground controlling it that the feds care about.

There was a guy in New Zealand a few years ago who built an autonomous jet powered vehicle (the “DIY Cruise Missile”) and got shut down (some of the evidence suggests that the NZ government was pushed by the USA to shut down the project)

This was done a while back in Canada. Apparently they had a scare when it flew directly over an airport by accident, but nothing came of it.

That can't be right, because people fly R/C model airplanes all the time.

In the Paparazzi Wiki, they controlled 3 planes and not 2. 1 in France, 1 in Germany and 1 in Turkey.

The future European rules, for smalls UAVs are very simple, keep it under 400ft, have less than 150kg, max speed of 70kts, range 500m. Important, no flying in populated territory, unless with special authorization.
US rules shouldn’t be very different.

>homeland security might get suspicious

It was while building my weather balloon, I had the idea of making a Glider that would fly it's way back home. I was told that the balloon was fine because it had no control (it came down on a parachute,) but as soon as you have any some sort of directional control the Feds want to know about it. That's what I was told, don't know if it's true or not.

This kind of thing actually gets into a bit of a gray area. The FAA has an advisory circular giving guidelines for operating model aircraft that recommend not exceeding 400 feet of altitude or flying within 3 miles of an airport. (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/0/1ACFC3F689769A56862569E70077C9CC?OpenDocument&Highlight=91)
Generally if you stay within these rules they're not going to care. HOWEVER, the FAA has notified manufacturers of small UAVs that these rules don't apply if they're being used for commercial purposes. If you're building your own UAV as a hobby, you're probably OK following the model aircraft rules.

Almost_there, I believe you are talking about a “guided missile”, not a UAV. And yes, those are illegal to make, and yes mike, the faa will give a hoot then.

the faa doesn’t give a hoot about what you build as long as it is under a certain size or if it is going to be carrying passengers. homeland security might get suspicious if you buy the model airplane stuff and explosive materials and bomb making stuff though…

>why would the nsa/fbi/ care about a personal uav?

Because with the right sensors it "COULD" be programmed to crash head-on in to a full sized aircraft (carrying some small amount of explosive.) Not that any sane person would do that, but they don't know who you are and they don't trust anybody.

@2: why would the nsa/fbi/any other 3 lettered government organization care about a personal uav?

I know the FAA doesn’t particularly like uav’s in controlled airspace, but that is a whole other can of worms.

I wanted to build an Autonomous Model Airplane about 10 to 12 years ago, but someone talked me out of it saying the NSA/FBI would be all over me. It would have been cutting edge then.
