Besides having Super RC powers, Dave Powers of RCPOWERS.com has a great interview of Dick Kline. Dave has spent a lot of time trying the KF airfoil on different platforms, most of them originally unstable without the KF. Dave has come up with some interesting results and as always, Dave’s videos are entertaining and informative.
If you are looking for a discussion and some plans, then head over to RCGroups for the Kline Fogleman Airfoiled Flying Wing thread. Perhaps one of the best reads on the KF is by Rich Thompson of Tennessee, or Leadfeather as he is known. Besides a great thread, Rich has put together a PDF of his research and findings: KF Airfoil Comparison by Rich Thompson.
The stability of the KF Airfoil has led a lot of pilots to use it as a platofrm for aerial photography, such as Aerophilia down in Melbourne, Australia. Using Tony’s BluBaby with a KFm2 airfoil the platform is very steady. With the KFm2 airfoil the platform is very steady and the video is clear.
