So I spun the hub on my SS viper 3 blade which would operate about 5400 rpm @ wot. It is thirteen seven/eight x seventeen. To get me by I bought the closest match accessible at the time, an aluminum hustler 3 blade thirteen one/4 x seventeen. Its only hitting all over 5100 now wot. I believe I can even now exchange it. The motor is a a hundred and fifteen etec, which I believe the wot variety is a thing between 5400-5600. Seeking for information on which way to go, shifting diameter or pitch, to get back in variety and better accommodate for the flex of the aluminum.
