Terrific, from the time Professor Lippisch was addressed "Hei, Alex" :-)
The aerodynamical torsion, expressed in the evolution of the rib shapes from mid to wing tip, is a remarkable job with all calculated and drawn by hand!
I have full respect for this, I remember doing work for this in the 80s in some early worksheet application, and then putting in all the calculated rib coordinate points into the CAD thingie by hand, one by one! Now try doing the same calculations by hand.
On the other hand, everyone had to do that, Spitfires to Messerschmitts, Boeings to Nakajimas, that was how it had to be done :-)

* 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.
