Remember the Prince prop has more to it than just wood. Lonnie Prince says it's no problem to adjust the pitch up. If I remember right (from 12 years ago), he told me he would rather add pitch than take pitch out of a prop. I didn't ask about the process, but I would assume they fill some on the blades before wrapping it with CF again. With a wood prop, it's difficult to add pitch by cutting away wood and it's generally not acceptable to try to add wood to a wooden prop. As you say, that is indeed problematic. Even removing pitch by cutting back the airfoil, you end up with a different airfoil from what would have been originally planned for that length and pitch. So there's a bit of guess work involved when reducing pitch and the efficiency of the prop is typically not as good as if the prop maker had planned the prop to be that length and pitch from the start. -Jeff Scott Arkansas Ozarks _______________________________________________ Search the KRnet Archives at https://www.mail-archive.com/[email protected]/.
