[TowerTalk] Correct downward pressure on Rotor?

[Kenneth Mathews]

Hello All,
I have a question about the amount of downward pressure that a rotor 
should have on it. I have heard before that you do want some pressure 
on the bigger rotors? Is this true? 
I have a tailtwister 2 and at present it has no pressure on it, the weight 
is at the bearing plate. It has jammed once and I know the bearing 
worked well at installation. Could this have jammed due to no pressure 
on the rotor?. It has 12 feet above the plate and 8 feet below the plate.
All ideas are welcome. Thank you all in advance. The many ideas 
shared here on this reflector has helped me many times over.
