Every now and then I hear from people that all "bush pilots" use 2-blade props because they pull better for STOL and floatplane operations. I'm not sure I really believe this. How could a modern 3-blade prop, correctly sized to the engine, and pitched properly not "pull" as well as a 2-blade? I think it is agreed by most people that the newer 3-blade props are more efficient, quieter and have less vibration than 2-blades. I would like to hear some engineering facts on this subject, rather than hearsay.
