Is it true that all Bravo 4 blades are actually 1 inch less pitch than labeled? Or is that just when you buy a new labbed prop?

For example, I have a 27 mach 4 blade, and would it take a 28 bravo to match that??

Thanks

Git er done

Yes, when you pitch read them, they are a inch low. However, the cup heights are high and need to also be taken into concideration. I usually use .7" less than the stamped pitch for calculations. It will very some if we actually have the prop here to read.

The 28 B1 will run less rpm than the Mach by around 100 rpm.

That's great info about the mach..I think I should try a 29 or 30 bravo then.
