It's not any more dangerous than any other plane, they all have hazards and are not to be considered harmless toys. It just didn't sell well enough to stay in production or something better came along as in the case of the radio system. Constant improvements. Has your friend/neighbor flown before? If not he needs to find a beginners type plane and master it before flying this one. This would be a much better third plane or possibly second depending on his aptitude.
