Anyone with experience using qprop?

Greetings.

I've been looking at this program on and off for a year or so.

Dr. Drela included some example files for F1D props, specifically John Kagan's.

Silly me, I like to understand things. So I follow the documentation and after computing the polars for a 3% arc file (as generic as it gets for prop airfoils), I try comparing to the examples.

And as you might guess, nothing matches. Some things are close, however I cannot understand how he got the numbers in the example files using the polar at Re5000 as indicated.

Is there anyone on-line that I might work with offline a bit to understand this a bit better? I have to assume I am doing something wrong...

Regards.
