I had a balsa nose cone version Cherokee D. I might still have the nose cone from that kit. The original "short" Cherokee-D didn't include any nose weight and flew well. So I doubt the switch to an 18" long tube had anything to do with stability. In my opinion it had more to do with streamlining production.
