voight-schneider animation edit

Hi, your voight-schneider animation seems to me to be an incorrect interpretation of the way the system functions. Your diagram suggests it functions as some kind of paddlewheel rather than on an airfoil principle. The contradiction between your diagram and those further down the article in which it is used on the english wikipedia is readily apparent. There is more detailed discussion on the german wikipedia about the problem with your animation. Cheers - A Hill. (user 1812ahill on en.wikipedia)
