Hi Mad Scientists,

I have a question concerning helicopters, more specifically, the length of 
the blades of a chopper.  If I wanted to make a helicopter, what would the 
ideal ratio of total length of helicopter blades (using only two blades), 
to the weight of the object it is lifting off.

Thank you for your time and cooperation put forth.
