Changing prop pitch?

[jamin]

i told you already see that info you not getting let me try to explain again about your prop specs. that (cob) means center of balance meaning measuring the pitch from the ttwo pitch equations you need one is from the diameter 45.67mm or 1.8" and the other you don't have but have the total pitch final answer witch isn't the same but you can finsh the equation by basic math 2.81/1.8=1.56 the other side of the pitch dude get it.

make some sense now

What do you have to do to change pitch from stock?
I understand there is some math but how is it physically changed?

[britscoot]

are the blades twisted slightly?

[jamin]

of course the blades are twisted otherwise they wouldn't work at all

[jamin]

and you have to file and balance and sharpen the props once you get them

[jamin]

or you can pay to have someone do it for you

[jamin]

offshoreelectrics does it all the time

[jamin]

they will even help you pick the right prop if you need that kinda help

[britscoot]

ok it seems you dont understand my question.
your making it sound like i have to write some numbers on a paper towel and rub the prop with it and that will pitch up the prop.
i know how to cup a prop and S&B.

Hope this helps.
