Quote: "Old Timer of the Month: Outdoor Tractor, by Jerry Ritz.
Text by Bill Northrop. Our Old Timer for November '87 was drawn up from Frank Zak's 1937 Model Aeronautics Yearbook by Frank Blair, of Warne, North Carolina, who also built the model in the photo [more pics 005]. Designated the '1936 Outdoor Tractor' it was one of numerous designs by the late Jerry Ritz (Gerald Ritzenthaler), and possibly one of the first, to feature his 'Ritz Wing,' as it became known.
The Ritz Wing was a single-surface, sheet balsa wing from which a large amount of the interior surface was re-oved, leaving a wide but thin eading edge, trailing edge, root, and tip. Thin, indoor-like, constant depth, undercambered ribs were then notched into the sheet surface. The planform was usually a beautiful single or double elliptical shape. The Ritz wing was later used by other modelers, probably the best known example being Scotty Murray's beautiful Answer (oz3).
Jerry was also the first to produce machine cut gas model props, offering unfinished ones for 15 cents, and finished for 25 cents. They were included with most Comet gas model kits.
In 1959, Jerry won the individual World Championships for A/Z Nordic, in Belgium, bringing the team up to fifth place.
We're not sure of the date, but not too many years ago, Jerry lost his life when a structural failure occurred while he was flying an ultralight of his own design."

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
