SSM 5 blades verses 4 blades.

Question.....
Large pitch (35 and above) SSM props, what would be the rpm difference between a 4 blade and a 5 blade prop of the same pitch and diameter?

350 rpm min. less on the 5 blade and more stress on the drive / tranny !

General rule of thumb is 150-250 R's (200)
