Does anyone have any experience with these Piranha props? They have an aluminum hub with replaceable composite blades. Seems like a good idea on the outside. Good price, easy on the drive line if you hit that big rock or stump and cheap to replace the blades if you destroy one. You can also replace one blade if you damage only one blade ect. They claim the blades are identical in weight so balance is maintained. Their website has a clips from a dozen or so good articles from major magazines that gave them good reviews. I also like the idea of being able to experiment with different pitch angles cheaper than buying an entire prop. Opinions for a 25 HP Honda application?
