I am getting close to pulling the trigger on a Catto prop for an older RV6 I am building. I have a freshly overhauled 150hp O320 on there with the 4" spacer.
Would you go with a 2 or 3 blade prop? It sounds like the performance is the same but the 3 blade is smoother? Would that be a correct assumption?
Are there any RV6'ers with a 320/Catto combination that could weigh in?
Catto was recommending a 70"x69 pitch for the two blade setup.
Any guidance would be appreciated.
