Why bother losing 5 kts and $4200 ? Photoshop a 3 blade on your -12 if want to send a picture looking cool. Makes me want to switch over my 2 blade Sensenich to my Rans S21 to see if I can improve the performance.

I think it was more than looks and performance. With Van's incorporating basically an annual dynamic prop balance, dealing with that protractor, the different weights of those sensenich blades etc.

When you compare the 3-blade Sensinich pricing and all the parts and spinner from Vans it probably isn't that far apart. Of course the ELSA certification for builders ordering kits adds a wrinkle, so Vans really needs to offer this as an option imho.

Suppose you operate at higher elevations (Denver) and want more pitch? Seems like ground adjust would be answer as opposed to a "fixed" fixed pitch prop...

I finally got my Catto prop installed on my RV9A 0-320 160 HP Lycoming. Besides looking cool, it does everything Catto claims. I can only get 2500 RPM so far at 3 to 5,000 ft altitudes WOT. My static RPM is 2180, which is a bit low. With the Sensenich prop I could easily get 2600 RPM and static was 2250. So that's the only issue so far. The prop really works good as a brake when in the pattern, which is what I need for my grass strip that has rising terrain at both ends.
