I experience the following problem:
During taxiing or take offs the plane suddenly moves to the left or the right. When I watch the taxiing in chase-view it seems that the rudder sometimes moves to a side without an explainable reason. When I allow X-plane to control the plane exactly the same happens.... a lot of squealing tires and the plane stops moving continuously or ends up in the grass. It makes no difference whether the joystick is connected or not. Al planes exhibet the same problem.
I'm using X-plane 10, v 10.42 64 bit
