I thought a place to discuss the Kline-Fogleman modified airfoil, would be right at home here on the FT forum.
I have not been into planes very long, but already my RC addiction has given me an itch I just had to scratch.
While looking into how to scratch build an airplane, I discovered the KFm airfoils, and how they work.
I like how easily an efficient airfoil can be produced by simply folding, or building up, and stepping down the thickness to a prescribed amount. This makes model building so simple even a Monkey could Fly!
I did some modifications to the foil I made (see scratch link above), and I'm not sure how it will effect the lift properties, but I can't ever leave well enough alone, and had to put my "touch" in there.
So what are some of your experiences with KFm airfoils? What have you found to work well, or not so well for you. I would like to learn a lot more about them, as well as provide some good info for others just getting into, or actively building scratch planes.
