I thought the same thing at the time he came out with this, as those tabs are typically called "aerodynamic balances". But he's the aerodynamicist, not me. Somebody needs to make this change to an already-flying KR2 and report back on the difference. Mark Langford, Harvest, AL ---------------------------- I did make those changes to a flying KR... 12 years ago in 2005, and reported back. <http://jeffsplanes.com> The feedback I got was a few remarks directed at my apparent lack of pilot skills and ignorance about aircraft design, and the implied need to make my KR handle like a truck. I flew 500 hrs with the old tail. Now 650 hrs with the new tail. The impression I got back from the KRNet folks was that I had insulted those that had built to plans by doing something different and was somehow calling all their babies ugly. I will say, the elevator does load up at speed to the point of being comparatively heavy. Gives it much more of an RV type feel at speed. That is a nice feature as it makes the handling at speed very smooth and keeps one from over-controlling at a speed that could cause some serious problems. The elevator is still quite light at low speeds, but has a lot more feel to it than the previous tail. -Jeff Scott Los Alamos, NM _______________________________________________ Search the KRnet Archives at https://www.mail-archive.com/krnet@list.krnet.org/.
