About this Plan

1955 Nordic Winner. Nordic glider champion.

Quote: "The marvelously efficient tow-liner twice won for Germany. 1955 Nordic Winner, by Rudolph Lindner.

This winning A/2 for '55 is a development of my 1954 championship Nordic model, Spinne -in English, Spider. Even though Spider combined stability and low sinking speed, the 1955 champ shows further improvement of both characteristics. The fuselage and tail assembly are completely changed on the new model, while the wings are of the same type as on the 1954 plane. Here are the reasons for these changes.

In order to improve flight stability and, consequently, efficiency, especially during thermal flights, it was necessary to reach a lower momentum of inertia. This was accomplished by lowering the weight of the tailplane carrier. The change of this section included a new profile as well as a new frame, resulting in slower sinking speed. Numerous flights for the purpose of measuring the testing differences between both models have demonstrated the correctness of this theory.

The 1955 champion attained the very low sinking speed of only 11-1/2 in per second and still showing good flying stability. Now, since this model is meant for advanced model builders, discussion is limited to only the most necessary instructions. The plan shows everything necessary, including materials and measurements. To avoid later difficulty, it would be best to select Materials carefully.

It is up to you to pick your starting point; however, experience seems to prove that starting on the wings is best. In order to cut the balsa ribs to the exact shape, it is necessary first to cut ribs W.3 to W.10 out of 1/16 in plywood. Since balsa slips off the plywood too easily, drive two pins into the plywood until 1/16 in of them penetrates the surface of the plywood templates..."

Notes

* 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.

Scaling

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.
