Reading through the many insightful posts, particularly on fuel mileage, rpm's, and efficiency...i saw many comments referring to 20, 21, 22 pitched props. This makes me question if 19's are appropriate. I expect they are original, and would think that 19s would give higher rpm than higher pitched props, but my rpms at WOT seem to be 3000/3100 max.
Just looking for insights and clarifications. Thanks in advance.
