I believe that anytime you get a young person involved in activities that have a positive influence it will help them grow as a person and hopefully steer them away from negative influences. There's a lot worse and more expensive things a kid could be doing than building and flying RC planes. If you know a kid who is interested in flying but maybe mom (dad is probably not around) can't afford it then take up a collection at the field and buy him/her a trainer (or get one donated) and teach them. If it saves that one kid from drugs and crime/prison and maybe turns into a lifelong passion as it has with so many of us here then it will be the best time and money you ever spent.
