===Gossamer Condor===
Control reversal also affected the [[Gossamer Condor]], the [[Kremer prizes|Kremer Prize]]-winning human-powered airplane. When a [[wing warping]] mechanism was tried as a solution to a long-running turning problem, the effect was to turn the airplane in the opposite direction to that expected by conventional airplane knowledge. When the Condor was rigged "conventionally", the inside wing slowed down so much that it settled to the ground. By employing "backwards" wired wing-warping, the inside wingtip [[angle of attack]] was increased so that the added drag slowed that wing while the added lift allowed the airfoil to stay aloft at a slower speed. The tilted canard could then complete the turn.<ref>{{Cite web |url=http://www.humanpoweredflying.propdesigner.co.uk/html/the_gossamers.html |title=The Gossamers (Archived copy) |access-date=December 19, 2021|archive-url=https://web.archive.org/web/20150419063651/http://www.humanpoweredflying.propdesigner.co.uk/html/the_gossamers.html |archive-date=April
