A little confused here... at the bottom of the downstroke the wings  
are just coming to the end of a chiefly horizontal segment in their  
stroke cycle, the south pole of their circular stroke, if you will...  
unless the wingstroke only operates chiefly in the horizontal plane.  
Maybe this is the key >> do you envision a manus stance much wider  
than the pedal stance?
