(Post updated 10/6/09 with new graphic from Dick Kline. Now includes 9 KFm Airfoil Variations. See below)
I just wanted to post a new graphic that Dick Kline was so kind to share with me. As many of you are probably already aware, Dick Kline the inventor of the KF Airfoil is always tuned into how we in the RC community are using his cool invention. Mr. Kline also enjoys creating computer graphics of many things. Well recently Dick Kline sent me his revised graphic that depicts the well known variations of the KF Airfoil as well as some new versions that people are experimenting with. Dick wrote me a few brief emails below with the attached graphic. I wanted to post it here and share it with the rest of the RC Community and all that may be interested.
Here’s the Emails:
I wanted you to have a copy of the visual I came up with showing all the different variations of the KFm Airfoil Family. They have multiplied like rabbits.
Well, two more additions have arrived. One is an under-camber with the step on the top. So, that goes next to the under-camber with the step on the bottom. I’m told that they both work extremely well.
So, here’s the KFm Family of nine airfoils…
(Here’s the graphic made by Dick Kline, many thanks to him for providing it!) (updated 10/4/09)

Later I will try and get some written descriptions of each Airfoil and what benefits each provides. So please stay tuned, we want to keep this blog going as a good resource for KF Airfoil information.
If anyone would like to contribute their findings on the KF airfoil please feel free to email us at email@example.com. We are hoping to help Dick Kline spread the word of his cool invention and share the collective knowledge we all have.
Happy Flying to all,
