I agree with Hydro Junkie. Several years ago I used to have 5 or 6 students I was helping during the summer, last year I had 1. And he was a guy that used to fly and just needed practice to get back into it. Kids these days get some little RTF foam plane or quad-copter and buzz around in their back yard. When they break it or just get bored they move on to the next new toy. Nobody wants to make a commitment to build and learn to fly. I have no idea about how to change that though.
