Hi Rinker,
if you ever had a loose scotch tape on a blade or a plastik basket fiddling with a blade, you won´t ask the question.
Blades are not designed to cut trees - and if you´re realy unlucky, you missed a thick piece and what happens then, you can watch at the videothread at prrune.
Yes, they´ve done it in nam - but beeing under fire and having a Huey is something totaly different to doing it on purpose in peace-time.
I´ve seen the blades of a 205, which went through branches cause it was overloaded. The Bird made it, some windows broken - and scars on the blades. Lots of repair needed....
