I chopped my trailing so I wouldn't have as big a mass balance weight on my ailerons. They can be big and ugly James c Ferris <[email protected]> wrote: I believe you can increase the thickness to about one percent of the chord without adversily changing the performance. When we were developing the supercritical airfoil for transonic performance gaines we increased the trailing edge to about .075 chord without reducing the performance, this was mostly for structural reasons.
