According to the owners manual, the fixed-pitch Cherokee 235 is a couple mph faster in cruise than with the constant-speed prop.what are the performance differences between the fixed-pitch Cherokee 235 and the c/s one? Naturally, it means longer takeoff roll and lower climb rates, but by how much? Is the f/p prop still much cheaper? I would assume it’s still considerably more expensive than a prop for the 180. And would the cruise speed still be same? Perhaps fuel burn is less due to lower rpms, but by how much?

But as expected, takeoff and climb are a little better with the constant-speed.
