Dick,

I'm interested in dynamic scaling, some of which is obvious, but most is not. For instance power is to the ratio of scale to the 3.5 power. And scaling time (scale ratio) to the half power. I've seen some NASA documents on the subject, pictures of spin tunnels and the like. I like the analog puzzle of aerodynamics in the digital world. I hope to design an single place homebuilt after I finish my RV-4, but would like to build a half scale model to test first.
