Bill H.  Re: drag increase with stall strips and associated decrease in cruise speed:  Theoretically if the strips are placed at the stagnation point there should be very little drag and therefore very little cruise penalty (forgive me if you already knew that).  I did not do an exhaustive investigation, but did NOT see any significant difference in cruise at 75% power with and without the strips.

Re: some other comments:  Of course properly installed strips do not change the stall, they change the stall warning.  I used the strips to find the region of the stall safely, then I removed the strips to investigate the actual stall characteristics.  If I decide to replace the strips it will be to induce an aero stall warning a few knots prior to the stall, to augment the aural warning provided by Chelton.  Now if I wanted to change the stall behavior, well that is a different matter--that would take a lot more testing and experimenting.
