Re: Prop size for 4-107

JonB:
I don't know about "square" sail plans. I'm not sure I would go along with that theory.
But for props diameter is the more important number so it figures you should give up pitch for more diameter. You size or diameter first then pick the pitch.

The way I size a prop is a method I have used very succesfully for many years. I pick up he phone and I dial:425-355-3669

This is the phone number for Max-Prop. I ask for Fred or Fredrique. They both know props well. Then I do exactly what they tell me. It never fails.
