Carl Goldberg Classics is still offering the Super Chipmunk. I built one about two years ago. Still very good quality. The glue joints on your dad's plane may have gotten brittle over time especially if it was assembled with Ambroid, which was a pretty popular glue back then. I put a Saito 100 in mine and it flies GREAT.
I just dug it out of the upstars of the the barn and cleaned it up. It cleaned up pretty well. But I would never try and fly it. It's just a neato wall hanger at this point. I'm going hang it up in my basement hobbie shop I'm putting together since I'm getting back into the hobbie. And I want to build a new one...
