OK Gang, we have beat both sailboat sails and surface finish to death and the
posts are coming slowly. How thin does a trailing edge need to be? I know,
what cord, what speed, what airfoil? Lets say a 10 inch cord, at cruise, and
make it an SD 7036. Would it change if were a HLG with 5 or 6 inch cord? Does
the amount of camber change the needs of the trailing edge? Aerodynamic
engineers, and would be aero gurus, all can reply. Later, Rich
