Default Re: Prop Pitch & Diameter

Going to the "great deal" props with 2" less pitch, but 3/8" greater diameter should be similar to same diameter, but only 1" less pitch. You should gain an extra 100-200 max rpms, roughly speaking. But then blade shape, rake and progression all play a role as well. Try it and see.
