Part of the problem with these devices is accessibility. It's been common for a long time for people doing RC to get involved in clubs, build their own aircraft, understand how the aircraft works (how it flies, its engine, its radio components).

Quadcopters seem totally 'plug and play'.

I'm involved (somewhat) in high-altitude balloon flights and we have a similar problem. People want to be able to buy a kit of everything they need to launch a balloon into the stratosphere. There's been a lot of resistance in the UKHAS because we want people to learn about the entire process (and that includes safety).
