I really do need to get my hands on that book.
My library dosent have it does anyone know where to get it?
It's on the Net here [link]http://www.edj.net/2stroke/jennings/[/link]
I know im using an 18-8 but i just cant see that making that much difference.
You bet it makes a difference in prop speed, a BIG difference. See post #195. jester241 said he's using and 18x6W prop. It sure looks like it's an APC prop! If it is then his motor would turn about 7000 rpm on an APC 18x8W prop.
