I expect this is just the beginning, and we'd better get in all the fun we can now because heavy restrictions are coming.
I say this because of the P4 and drones with similar capabilities. It's now easy for anyone to fly well enough to be instantly dangerous.
I remember when I was starting out on RC helicopters... The hours of work just to be able to hover in place scared 99.99% of interested people away. By the time you could actually fly one anywhere, you were good enough to not fly into buildings. You had an immersive awareness of the helicopter -- its hard to explain, but when this "clicks" all the orientation issues go away (like when its pointed any direction but away).
No need to develop these senses to fly a P4. A kid can do it out of the box, and what's worse, fly FPV out of LOS, where there are people, poorly aware of what's NOT in their field of view.
Hell, I've been having a blast (and been amazed) with my Parrot Mambo that arrived a few days ago; has Visual Positioning, ultrasonic and barometric altitude sensing, a six-axis IMU. **** thing hovers in place pretty well in gusty wind -- I was shocked! It does get pushed around a bit more than the P4, but still does a pretty good job of staying in 12" or so sphere of where you release the sticks in gusty conditions. The stability system is more than adequate to make it easy to fly like the P4 -- that is, no skills needed. Only saving grace is no FPV through a camera, nor GPS to make something like RTH work. So it's strictly LOS.
Still, for a hundred bucks, anyone can have a small missile that can blind someone.
I absolutely love this hobby, am looking at ways to make it a business. However, I don't see how this all doesn't got to s h it pretty quick. Sorry for the depressing forecast. I hope I'm wrong, but would bet I'm right.
