and would love to hear some aerodynamicists weigh in. My first roadblock to acceptance is in trying to imagine that an object capable of disrupting such a small % of span-wise flow on one wing could change stall characteristics so drastically. I can't make myself picture it. Guess I'll wait for the yarn tuft video
Secondly, I can't grasp how an asymmetrical change that raised overall stall speed by almost 25% didn't produce a violent spin entry as stall was approached. The modified wing would had to have let go long before the other. Scott describes not wanting to explore the stall, even armed with a large rudder, and I understand the reluctance (!) but this would be a situation of Russian proportions: "In Go-Pro motherland, stall explores you!"
My brain's refusal to believe what is posted is no one's problem but my own. No flames. But I just can't comprehend how this happened as described - and would love a sound explanation of the mystery. Have skin in the game since I've taped a Contour to my wing and empennage many a time with no untoward effects and want to keep doing so without hurting myself.
