I REMEMBER!!!!! It was the thrust bearings in the tail! What would happen was when spooled up and the thrust bearings got a certain amount of load on them they would lock up then when spooled down the load was less and they would work fine. My fix was to upgrade to angular bearings and metal grips with the new hub designed for angular bearings. Im 99.99999% sure this is what is going on! Took me a while cause everything worked fine on the bench but wouldnt when spooled up.

All Replies Are Good And Make Sense.
#1 You Guy's Are Great, Thanks For The Replies !!!
I Am Heading To The Garage Now And I Am Taking All The Above Apart.
I'm Also Gonna Check The Runout On The Clutch.
I will Go Thru Everything Mentioned And Replace Anything That Feels Lumpy Or Stiff.
Doing It One Thing At A time Will Let Me Know The Exact Problem When I Fix Or Replace The Item in Question, But I'm Past That Point, I want To Do It Once And Fly The Piss Out Of This Thing !!!!! The Engine Should Be Pretty Loose By Now, Got Almost A Gallon Thru It Spinnin Around On The Ground Tryin To Figure It Out. Whats A Few More Bucks And A Couple Of Hours In The Man Cave !
Thanks Again Guys, I'll Keep Ya Posted On What I Find...
