APC Props
#3
I'm by no means an expert on the subject but it seems the most common prop is the 8.8x9.25... If it's really hot and humid or your engine isn't a real hoarse, then the 8.8x8.75 works well... That's what seems to be the most common that you see on here anyway.

The 8.8x9.25 seems to be the fastest, however, most people can't ease off the sticks enough to get the best speed out of it. The 9.25 also is a tricky prop to get a good needle setting for many people. Take some time to practice with it, and a good engine will really haul with this prop. The 8.8x8.75 seems to be the best overall prop for the average racer. Easy to needle, good acceleration, and pretty good top speed.
