anyone else find these? i was looking at some 20b's and came across them.
apparently the 6 rotor is made for an airplane and i think the 12 rotor is just for fun

here's the thread

The Hurley 6 rotor never ran..... the 12-rotor was just a mock-up

 

aaw that's sad... would have been nice to hear it..
as for the 12, i know its just put together for looks, still funny to see

 

What is the largest operational rotary?
