All decent =C2-airfoils have laminar flow at the front part, from the nos e to the thickest part of the wing.The nose of the airfoil is the most sens itive part and any disturbance there results in turbulent flow.Ask glider p ilots. They will tell you that bugs smashed on the front of the wing can si gnificantly reduce =C2-performance of the glider.Supposedly even a color strip painted along the nose of the wing is no good.

From: Alfred Rosa Many certified planes have tape or de-ice boots on their leading edges. I never heard of losing speed being a concern.

Actually loss of speed is one of the big issues with de-ice boots and there have been many studies of this. Most modern jets use heat on the leading edge instead of boots for this reason along with others. Real life laminar flow does commonly happen. Even in the slip stream of the prop. The whole idea of a laminar flow airfoil is to extend the amount of laminar flow farther than a conventional airfoil. Even a conventional airfoil has some laminar flow and to 25% cord or more is typical. But for many KIS owner/builders the speed is not the end goal and this should not be large. For others speed is more of the goal. To each their own and that is why we all end up with different aircraft even when we started with the same kit.
