Hey Mike, Mark here. I know the last three photos (one with the US flag)in that post are from the RC3 (Radio Control Club of Chicago) pattern meet at Kickapoo Woods in Harvey, Illinois (and I'mcertain they are you). I'm gonna guess circa 1972-74. I was 17 and was just staring in 74. In fact, I have a large jacket patch from the RC3 club that I keep highly preserved on my dresser. Not sure if you'll see this old post but I had to comment on those pictures. If you recall a young one-armed guy flying single stick, that was (still is) me, and I still have the old Pro-Lin Comp 6 that a good friend gave me way back then. This is too good!
