i don't get this - control-line planes were very popular in the 1960s and were not particularly dangerous. I built and flew a couple of diesel engined ones myself - not very well, it has to be said. the main danger was not getting your fingers out of the way of the prop when you flicked it to start it. the advent of cheaper radio-control systems kind of saw them off. one of my flatmates in the 70s built a beautiful r/c slope-soaring glider.
