Terry,
Great comparison - and risking serious thread creep, I couldn't help but notice this sentence from the article: "The reason we do not see dimples on other shapes, like wings, is that these particular forms of boundary layer trips only work well on a blunt body like a sphere or a cylinder."
Thinking of the front end of a 150, maybe it should have dimples...
I bought my Cardinal with some very noticeable hail damage; well over 100 dings of various sizes. In the time I owned it and flew it a little over 1000 hours, most all of the dings simply went away. When I sold it, I disclosed the hail damage. The buyer asked me to show the dings to me; it took some looking to find the few that were left.
Warmest regards,
Rick
