[NSRCA-discussion] Rudder pull-pull

[James Oddino]

The way I see it, the mechanical advantage is constant (assuming a  
wheel on the rudder) and is in fact no mechanical advantage as the  
radii must be equal to keep both cables tight at all rudder  
positions.  With an arm on the servo, the holding force increases as  
it moves away from neutral.  Picture the holding force if the arm  
moved 90 degrees.  You'd break something before you could move the  
servo position if you pulled on the cable.
