There are a lot of people doing UAVs in the RC hobby in booth planes and Helis. Nothing that can currently be built with Hobby quality and scale components comes anywhere near the point of being a National Security problem , where do you get your information?

I saw a pic of a British military UAV coaxial heli, it was a small full sized heli. To get 30 min and a electronic payload and long range that’s about what it takes.

I have also seen several videos of 450 trexs being flown from a 2.4 ghz wirless video camera. They are very hard to fly that way and don’t have much range. I also ran across an add at Hobby- Lobby.com for a camera / goggle combo. They are working on several modules for the setup including HUD style video overlays for flight data.
