Alright, how do I figure the FOC on my shafts?  I have just measured and they are 31" over all, and the balance point is 13"in the front, and 18" in the rear.  Can someone tell me what my FOC is, and how you figured it?

Thanks,

Mike

I used the search option on here and found that thread, but my computer won't allow me to open it.  That is why I'm asking for assistance

8 percent FOC. 31 divided by 2 = 15.5 - 13 (balance point) = 2.5 divided by 31 = 8 percent. Pretty sure I'm right..

8.06451% to be exact doing it longhand or plugging it into the computer.  
 
And i used....
(18 divided by 31) then minus 0.5 then multiply by 100.

THIS  is the foc calculator link - save it to your pc, then open it with any spreadsheet app.

Thanks for the help guys.  I was just curios where mine were. I figure as long as they are flying good, why mess with it.  After reading alot of posts from guys with huge FOC #'s, and others with smaller ones, I just wanted to see where I fit in.  I guess I have no need to over compensate for anything.
