Diameter of propeller Question?
What effect has using different diameters of propeller on your RIB?
I figured that a 21" Pitched 14.750" dia prop would be harder to drive that a 13.75 dia prop of the same pitch? What would happen to slip etc? Would it be better to go for a 19" stainless prop to gain the nessesary 500RPM needed for my installation?
Just having a think out loud for the moment as there are other factors to consider, like checking throttle position, making sure engines working correctly etc...
