Barry Schiff had this to say in his recent AOPA story of flying a 1956 182:
"The rapid climb rate caught me off guard. The 1956 model is so much lighter than subsequent models, has the same horsepower (230), and easily outperforms them. The owner’s manual—there were no pilot’s operating handbooks in 1956—claims a climb rate of 220 fpm at 20,000 feet at the maximum-allowable gross weight of 2,550 pounds, outstanding numbers for an airplane without a turbocharger."
Ya, I remembered reading this article last year or something so I went back through my AOPA stack and re-read the article. I think I am pretty much convinced on the '56 and now just need to find the exact one I want. There are a couple out there ranging from $36k up to $75k...I want and need to be down around the lower end. The one I am considering has a low time rebuild and is in pretty good shape at least from the pics I have seen. Hopefully it will look as good in person.
