Excellent question, Herbert, and one I've wondered about, too.
My wheel goes about 3 turns from stop to stop. That's 3 X 360° = 1080°. My rudder moves about 30° each way or 60° stop to stop. That's an 18:1 mechanical advantage, which is why Herb has to push so hard on the rudder to spin the wheel and move the rudder. (to say nothing of wheel diameter, rudder center of effort and friction)  
Granted the linear drive has a lever arm at the quadrant giving some mechanical advantage, but it seems it still must take much more force than the rotary drive.
Interesting discussion.
Cheers, Craig





This is not a question how the Autopilot works but how the Amel Steering works

thx, herbert
