We spent several hours in analysis of the stall characteristics, with and without stall strips, and large and small strips. We also calibrated the Jim Frantz AOA instrument. To summerize, 1. Stall strips do not reduce stall speeds. 2. Stall strips cause buffet 5-10 knots above stall speeds 3. While operating in this 5-10 knot regime, the airplane is docile and ailerons control normally. 4. The effect of this strip on cruise performance is negligible. Large (1/4") or small(1/8") All airplanes are different to some degree. If your airplane stalls normally, predictably, strips may be an annoyance. If your airplane always drops a wing, and tends to tighten up in a spiral, strips would be needed and helpful.
