Pah. A racing quad or hex can hit 50mph, no bother. And a Tek Sumo built up for FPV will outperform that thing, and be more satisfying, and safer, too. The problem with the commercialisation of ‘drones’ isn’t that ISIS get hold of them, it’s that rich brats who don’t give a shit get hold of one, and end up killing or seriously injuring someone with it. Without the time and love investing in building, debugging, and learning to fly these potentially dangerous things, they are just a high velocity but disposable play thing, that happens to bloody hurt if it hits someone. People have been making model aeroplanes and helicopters of similar and greater mass (and in the case of the helis, CONSIDERABLY more potential lethality) for years, with very few issues. Now that the great unwashed have gotten their mitts on them, the days of model aviation as we know it are numbered, I reckon. Sad.
