RE: real scale flight
Thanks again Dick for your excellent information! Good to know about the original airplane as it should always be the yardstick for scale modeling.
Funny poor chap, this errant raven, but those bird-model stories are also moving and heart-touching for me. Maybe one has to see such a model to realize why. [link=http://www.das-nurfluegelteam.de/fred_ludwig/storch.html]Here[/link]'s a stork model that looks and flies very realistic, too. Once it was thermalling together with four real storks (they came along) for nearly 10 minutes and nobody could tell them apart.
