Assuming that they have not changed the design for the worst, it is an excellent choice. I got better climb and cruise with a prop pitched about 2 inches more than a McCauley prop. The difference was small about 4 mph but noticeable. I did all this work and then updated to a LYC 032 engine in the Swift with a controllable prop.
