Having only begun this addiction 2 months ago, my wife of 36 years blatantly pointed out that she thinks I have a problem. It has often been pointed out to me that a less expensive hobby would have been more practical such as, uh, gambling or perhaps the ponies at the track. But she sure loves the quiet when I go to the field for a good day. I may well have a problem, I now have 7 planes, only 3 will fly at the moment, 1 is yet to be assembled, and don't even know what make & model 3 of em are! 

But, I still like crashing RC planes better than any job I ever had!
