Are you turning the YAW DAMPER SWITCH ON (overhead panel)?

Hi Markoz;

I checked at home and the situation is this:

with yaw damper ON - in flight, small movement of the rudder. To you have an idea, in level flight, if I apply FULL rudder left or right, you almost can't see the nose going left/right. The rudder ball moves a tiny to left or right. On ground, the rudder moves left/right quickly.

with yaw damper OFF - in flight, large deflection of the rudder (similar to NGX, for example). On ground, the rudder is steady.

Maybe this is how the 737-100-200 is. And I'm thinking wrong.

I made this video to you see, at ground, what I'm finding. When the yaw damper is on, at external view, I'm applying full rudder left and right.

Markoz,

I'm having more rudder movement with YD off, not on. Even with it on, my deflection is further than yours??

Take a look at this video, please:

This is what happen in flight. I'm thinking to do a reinstall. Or what I'm seeing here is normal?

I'm sure it's doing exactly as its meant to do within the limitations of FSX. The reason it would give better deflection on the ground is so you can taxi using rudder peddles.

Cristiano, the idea of the Yaw damper is to reduce the amount of Yaw (left to right movement of the nose/tail) on the aircraft. It stops the plane from behaving like a dog wagging its tail and therefore making everyone inside pretty sick. In FSX, the yaw damper works by limiting the amount of rudder movement rather than applying an opposite rudder input to yaw on the real aircraft.

In short, yes the 737 is doing exactly what it should. Very small yaw movements with the YD on and the full range of rudder movements with the YD off.

Markoz, I wonder if the difference in movement could be caused by different rudder calibrations between your and Cristiano's sims?

Cheers, Nathan

Nathan and Markoz;

first of all, thank you for your clarifications.

I have a Logitech Momo Racing Wheel, and I use its pedals for rudder pedal. Yes, it could be the difference.

About the rudder deflection with/without Yaw Damper, if it is right, this topic is closed for me.

I only asked about this because I had "the feeling" to have more rudder deflection with 1.0 version (but like I said, maybe I'm wrong) and if I compare it with CS 727 and another company NGX (I know, 727 is another airplane, and another company is another developer) I have more rudder with them.

I did not think something was wrong with the 737, but with my setup.

Once again, thank you guys.

Mickey, just a quick question, do you use rudder peddles? What is your "Null Zone" setting if you do use them? If the aircraft is receiving "spike" information from one of the peripherals, then the Yaw damper will try and respond by putting in an opposite rudder movement. This could result in the fluttering some people are seeing.

Cheers

Nathan

Just to add information here, I tested with almost 50% of "null zone" in my rudder pedals, and the fluttering remained.

And I'm flying with Yaw Damper off, because if I start a curve with it on, man, the curve becomes with a huge radius.
