Desc: The wing holds two tanks on each side. Note the fence at the far left margin. He said the wing was original super-cub, but with an extra 4" of flap (?) I was thinking 'span' at the time, and later couldn't remember whether he'd said 4" or 4' -- both seemed pretty unlikely. Think now he must have meant he'd added 4" of chord to the flap.
