I was hoping I could get some info on the OS .15 CV-A. I am getting ready to break this engine in. I am using the recommended break-in prop. I wanted to know what the rpm would be for this prop. I am putting this engine on an Ace Ultimate Biplane. Once I get this engine broken in, what prop would you recommend. I am not looking for speed, I am looking for torque. What would you guys recommend for a prop and the max RPM.

Thanks in advance
