Propeller Slip Calculator
> ( Pitch x RPM) / ( Gear Ratio x 1056 ) = Theo Speed
> ( Theo Speed - Actual Speed ) / Theo Speed = Slip
Use this calculator to figure out just about anything in regard to propeller, ratio, RPM and speed. You can change one parameter and recalculate the rest. Use the CalcT button to figure the theoretical speed from the actual speed and slip. Be sure to take a look at the Prop Slip page for an explanation of how to find your prop slip.
