This is one of the easiest to hand fly FS airplanes I've encountered. However the ground handling is abysmal. Most noticeable being on landing rollout. I literally can't keep it on a 150 foot wide runway. 

 

Anyone else having this problem? Is there a parameter in the aircraft config file that can be edited to fix this? I tried reducing rudder sensitivity, since the rudder and nosewheel are interconnected, or should be anyway. This didn't do any good.

Check the P3D SDK, aircraft.cfg files.

 

I use Saitek pedals, took me a while to set up sensitivity and null zones.

also reduced the P factor in settings (for props)

Solved it. I was landing with the yaw damper on. It seems this model is more realistic in that regard, than other FS aircraft. I never thought the YD did much in FS, but I guess Carenado has incorporated it into the flight model.
