Pietenpol Sportster. Rubber scale model.
Quote: "Our old friend Scotty Mayors offers you plans and instruction to build one of the finest performing flying scale jobs ever presented.
WAY BACK when the Department of Commerce decided to clamp down on lightplanes, and vetoed the idea of the safe $700 airplane, Mr. Pietenpol came through with a sport-plane which was proved safe, practical, economical, and which, exclusive of labor, could be built for $500! But like the rest of all sweet dreams about planes for the average man on the street, it just went up in smoke. The requirements of the D. of C. were such that Mr. Pietenpol's sportster could not obtain anything but an experimental license. Nevertheless, Pietenpols with but changes in minor details started to crop up all over the country. They were powered with a Ford Model A conversion.
A two place ship, it weighed 625 pounds without pilot and passenger. It had a takeoff speed of 40 mph, a landing speed of 35 and top speed around 75 mph. Not so bad for a plane that could be built in a back-yard. And it makes an ideal ship for the model builder who wishes a slow-flying, easily constructed, very stable craft.
The model is designed 15/16in to the foot. Changes from the prototype included lengthening the landing gear and moving the front wing strut a bit to the rear, as the wing is placed slightly behind the center of gravity. The engine is made simply and was taken directly from the original plans as was the rest of the model. Standard size wood is used. Construction is simple, results are gratifying; so let's go..."
Did we get something wrong with this plan? That happens sometimes. Help us make a correction

* 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.
