You guys are right about being lucky that your sons are interested in what your doing. I've always had a passion for anything that takes to the air large, small, living and man made. My son could care less. I've got AFPD and if I had this when I was a kid I would have worn the sticks out on it. He used it once. I bought him an Aerobird commander once and we flew it together twice. I'm hoping someday he'll come around. At least we have common sports intrests

God Bless All!
