Has anyone attempted to build a wind tunnel to measure drag coefficient of models?


This seems like a really good winter building project...
...assuming one knows what the hell they're doing!

How might one go about building one? What kind of airspeed would you need to get a meaningful reading?

Thanks for any thoughts!
