Hi, Vapilot2004
Many thanks for this information.
It is a tremendous help you have provided here.
To my surprise, I found out yesterday that the MD80 rudder pedal movement becomes smaller the faster you fly and therefore you should use less force at "full" rudder. I found this on the web.
"
As the airplane speeds up, the rudder authority is limited, but the gearing
between the rudder and the rudder pedal does not change. Since rudder authority is
limited, rudder pedal travel is also limited; i.e., full rudder pedal deflection is not
required to get full available rudder deflection. Rudder pedal force is a function of
rudder pedal deflection, so less force will be required to achieve maximum available
rudder deflection as airspeed increases"

I always thought that the faster you was flying the more force was needed to move the flight controls and it is apparently opposite on this big mashines.
I have also read this, and this fits very well with the data you have written.
"
A pull force of approximately 16 pounds would have been required for lift-off"

I can understand that, the necessary force on the columns for lift-off may fluctuate some kg. depending on trim, aircraft weight and CG.
These are important data for me because I try to create a super realistic MD-80 simulator. And the time for building flight controls is near.

MD 80 is a fantastic airplane and is my favorite.
