The older "speed" guys at the field pointed me to this prop since i had the tuned pipe on.... Said that it needed to get up on the pipe and turn RPM if i wanted to go fast. The plane is deffinatly fast! Im sure its 120mph at least goin off other planes that have been clocked at our field with a radar gun. I had a guy that flys Jets at our field fly my plane and he guessed it goin around 120-130mph. But that was just a guess and no radar gun was used. But i figure hes not too far off since he flys 200 mph jets a few times a week, and he would be more used to the speed. Im new to the tuned pipes and props in general. I havent been flying all that long. Although i fly good enough to be a AMA club instructor "which i am" I'm still new to the props and all that. I can just fly em LOL. Thats all i know.[ Its funny because ill be teaching somone to fly and theyll ask what some other persons plane is or something about it, and i cant answer there question about that stuff alot of the times[] I bet that makes em a lil nervous to be on the buddy box with me haha. But after i save there plane about 20 times in 1 flight they prolly feel better about flying with me.[8D]

Im a little hesitant to go jump to a 15inch prop. I dont want it to be too much prop, and not have enough RPM to get up on the tuned pipe. But ill see if anyone has a 15x8 or a 14x8 at the field this week that i can try out! And ill deffinatly let ya know how it works out. Guess its all a learning experience. And thats for the info!
