Subject: Re: Kolb quit revealed
I'm sure John would agree with me on this one.The supposed "Kolb Quit" is an approach stall (power off) while in ground effect. The power off stalling characteristic of a Kolb Mk III, properly built, i.e. with a center section and either good coverings on the upper rear pod or the engine bay frame covered, is for some buffeting and a gentle break. It is the ground effect part of the equation that makes the Quit so damaging to landing gear. I would be willing to bet a quarter that stalls in ground effect occur at 3 to 5 mph lower airspeed than they do out of ground effect. Since lift is calculated from the dynamic pressure equation (1/2 rho * Vsquared, where rho is the mass density of air and V is speed) That small reduction in air speed has a dramatic effect on the amount of lift the wing is producing and when it goes away, whammo ( I have the limp noodle aluminum landing gear legs to prove the whammo part :-} ). End of where John and I agree, I think.
Dennis, one more thing you might consider doing to further improve the slow flight characteristics of your Mk III is to seal the gap between the horizontal stabilizers and the boom tube. You will find two improvements if you do. 1) Rudder effectiveness is improved to the point that you can pick up a falling wing while near stall speed and 2) Because of 1) it is possible to hold the airplane in a wings level stall as long as you want while descending in a flat attitude at a vertical speed of 1200 to 1500 fpm down.
