Goes for regular aircraft as well. Next time you're flying passenger in a Boeing or Airbus, get a seat by the wing. Note the position of the wingtips on the ground, then compare to where they are when you are airborne at cruise speed.

Flexing spreads the stresses through the entire structure, whereas a stiff aerofoil would take the entire stress of the entire aerofoil to a single point - with catastrophic effects.

Flexing wings/blades is LIFE!

According to the German dude if it WASN'T for the flexing blades the vibrations would tear the helicopter apart. Now that would be even scarier.
