Bill has taken up the hobby of flying remote control helicopters. About ten years ago he flew RC airplanes with a local club. The attraction of the helis is that he can fly them just about anywhere. The smaller three fly indoors and the two big ones fly in the back yard or at a local park. At first the hobby can be frustrating since it is easy to crash and you spend a lot of time and $$$ repairing your mistakes. Eventually you get the hang of it and Bill enjoys flying circles, figure eights and just plain hovering around.
