That doesn't seem too low to me. It will wind up considerably in flight.
 
Catto Propeller ?

Dan,

Is this the two blade "New Gen." with stainless leading edge?

If so, I'm watching with interest since this is the weapon of choice for my similarly equipped RV-4.

Did you request a cruise prop from Craig ?

Please keep the information flowing.
 
I get 2150 static with my 66x78 three blade with an IO-360. I get 2750 at 190kts.

I think you're good.
 
Catto

That Catto prop builds speed very fast once you get going. Your static rpm is right where it is supposed to be.
