So my S1SS project has an IO-360 with a hollow crank and flange with lightening holes. That rules out a metal prop, which I'm okay with. What I'm curious about is whether I should buy a two blade of three blade prop. I've been told the load on the crank and flange is more evenly distributed on the three blade and it's much smoother, but I've also been told they produce a significant amount of drag. So much to the point of not being worth buying. I was sold on the three blade Catto, but recently discovered MT makes a 2 blade for the Pitts as well. Thanks for any insight guys.
