Kline-Fogleman (KFm) Airfoils
« on: November 09, 2013, 07:05:34 PM »
PlainFreak brought up the Kline-Fogleman (KFm) Airfoils in his 'DT Foam Board is my Friend thread'.
They are quite effective and easy to build with electric/foam models. Here are two links if anyone is interested in this technology. They work very well for 1/2A's and the wing design can be used for glow powered models.
For the most part I have used the KFm2 (modified with 30% cord step), and the KFm4 ( step 30-50%)http://www.rcgroups.com/forums/showthread.php?t=1296458

Thanks for the link! I was aware of the KF airfoil when it was new and followed it superficially for a while, but I hadn't realized how much use was being made of it or of subsequent developents. I was able to read some of the initial posts and then started skimming, finally looking every 10 pp. into the final few of the 400 pp. There's a lot of interesting input there! 'wish I had the time to read the entire forum thread.
