Question for the group. Is there a way to calculate the pitch on a prop based upon the max RPM and length of the prop? Reason being is I want a climb prop for my Champ. The prop that came with the project is a 50 pitch on an O235/115hp and it seems like that should be more of a cruise prop. Any ideas?

They are really very helpful.

If you have a 7ECA with a 0-235-C1, I hope you have a Mc Cauley, If
you do, contact them.
