Hey John

Welcome to the thread. Thanks for the compliments. You are correct in your observations - design is a compromise and when one is working toward a sport flying type of model but using a scale outline and trying to work in as many scale features as possible - well, irregularities always pop up.

To control wing twist a D tube wing section and some trailing edge sheeting would have been the solution, but (and there's always a but) the decision was to preserve the flavor of the original Eindecker and sheeting would have spoiled the look so the deviations from scale begins.
Where does it stop? I guess where ever the designer or builder choses to stop.

It is definitely an entertaining excursion - the trip down the road of design. Designing for one's self and a "one of" model just about anything is acceptable. But when designing with the long range goal of kit production many factors need to be considered - time and money being the most important to production........and ease of building and flying being the most important to the consumer.

A good friend and I are in the beginning stages of a half scale Eindecker EIII project and much of what you mentioned will probably be incorporated into that design/build.

I have run on far too long........thanks for stopping in and I hope you stay with us.

Cheers,
