1929 Monoprep - Radio control scale model. Wingpan 72in, wing area 820 sq in, for 35 or 40 power.
Quote: "That simple stick-and-former scale models have great appeal is evidenced by the literally hundreds of thousands of such kits sold through the years by such firms as Comet, Guillow, and Sterling. These designs are usually compromises between exact scale and the need for simple construction and good flyability. These deviations from true scale are also often present in the smaller rubber and gas-powered scale works of the classic designers such as Stahl, Struhl, Struck, Lindberg, and Winter. 'Silhouette Scale' is an effort to carry that universal appeal into larger radio-controlled models. The Monoprep as presented in this article is not exact or museum scale, but rather a blend of simple and light construction with good flying characteristics. Its outlines and contours are immediately identifiable, particularly in flight, yet it can be constructed in only a fraction of the time required for more con-ventional scale designs. Additional appeal lies in its ease of construction for the less experienced builder, and in its forgiving flight behavior for the less experienced pilot. Although its structure at first glance appears flimsy, it is more than adequately strong to withstand the rigors of sport flying. We have deliberately narrowed the fuselage, lengthened the nose and tail moments slightly, and enlarged the stabilizer area. None of these compromises is readily discernible to the eye, yet they greatly enhance stability and handling... "

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.
