6 kW Scirocco by Solacity Inc. [RE-wrenches]

[Jeff Clearwater]

<x-flowed>

Hi Hugh,

Thanks for the correction on the web site.

So, is the fundamental choice from 2 to 3 blades a trade-off of 
efficiency versus vibration?  Or is there a way to have both - a 3 
bladed machine that is as efficient as 2 blades  - or  -   a 2 blade 
machine that doesn't have yaw chatter (if such a thing is possible - 
perhaps at a low enough rpm?)  I know I'm getting into theory here 
but just wondered if there are examples of successful 2 bladed 
machines that don't tear themselves apart eventually.

Thanks,

Jeff C.
