Be sure to do the comparisons at the same weight for a valid comparison. When you achieve a stall increase that is in the 1-3 kt above the no strip speed, then try strips that are about 6-7 inches in length at the same location. The position becomes progressively more critical as the stall speed gets closer to the no strip stall. This work will improve your controllability without imposing a significantly higher stall speed. Depending on your wing contour problem 6 inches should be more than enough to improve the stall and buffet. Keep accurate records of your configuration and test. Jack Webb
