It will be interesting to see how all of these different combinations work out! I hope Scott doesn't beat me into the air..... but then again it would be nice of him to fly the re-fitted beast over to Mid Valley so that I could check it out. 

I wonder how my 325 HP Chevy will work out swinging a 76" 3 blade constant speed. Max pitch 105" 

The crystal ball seems cloudy the farther you get from known combinations :) 

Keep on plugging Scott.. I'd love to hear it .

Al,

Its 66" Diameter,  106" of pitch

Set up for 225 knots at 2500 RPM

The blades are very wide, much wider than the CS prop on the T210 with 
the same engine.
