RE: 12 6-10 prop. What pitch is it?
Oh, maybe I should have mentioned that I worked at a place that actually made wood propellers while in college studing for my engineering degree. The owner of the business had been making model airplane propellers since 1949 commercially, and knew all the principles in the industry. When these propellers came out, he called the guy, and they talked about it, so he really did know the reason. Since they served different market segments, they didn't directly compete.
