Default 3 bladed Fan Boy

Supposedly the three-blade is a bit lighter (didn't expect that) and has a slight performance improvement in some areas, owing, I guess, to the higher aspect ratio of the individual blades. Speaking to the Van's crew, I get the feeling that they think the performance is a toss up. I've decided to stick with two blades.

I came away with some opinions after seeing it at OSH, but fist let me say that I was a big fan boy when I first head about the idea that 3 bladed prop might be a great option. Now I have seen the finish product in person and I'm not as impressed, Here are my observations.

Pros. Is the coolness factor. Thats it, that's the only thing.

Cons;
Going to pay another 2,000 or so more on top of the engine kit for a little less noise and 40 FPM increase in performance.

So for this 3 bladed Fan Boy, I will have to pass, for now.
