    Default How to figure speed w/ pitch and rpm's

    Is there a basic way to figure approx top speed if you have the pitch and rpm's. I thought that I used to have a website,,something like Piranaha props,,that would calculate approx top speed. I realize there is some slip involved..But approx would do fine.

    mrtool2u, email me...I'll give you the system I use.
    I'd post it but it differs with prop type and would be confusing.
