I have a 74 x 88 Catto two blade on my RV-4, with a 13BREW & 2.85 redrive. I haven't flow it yet, but I think it will be a good prop. Catto makes good props.

Subject: [FlyRotary] Prop Selection
I am now Prop shopping for my RV-9 13B with the 2.85 RD1-C and am leaning towards a Craig Catto prop. Craig has recommended a 3 bladed prop 70" X 88". He says that a 2 bladed 76"X 88" prop would have to be 7 inches wide at the root and 3.5 inches wide at the tip, the three bladed prop would have a thiner look to it. Three bladed prop looks good sitting on the ramp, but nobody sees the prop when it is spinning. Ground clearance might be a problem with the 76" prop. Not sure, I have not taken a measurement on this as yet.
What other venders would the group recommend? I would like to hear some opinions.
