I am fairly certain the problem I am having has to do with contact points but not sure.
The problem is that most of the default aircraft in FSX will tilt from side to side when corning.
The CRJ is probably the worst one wheel comes completely off the ground.
When turning left the right wheel comes off the ground and vice versa when turning right.
What is the cause of this if not the contact points.
And if the problem is the contact points which ones do I edit.
contact points for the CRJ is below.
//0 Class
//1 Longitudinal Position (feet)
//2 Lateral Position (feet)
//3 Vertical Position (feet)
//4 Impact Damage Threshold (Feet Per Minute)
//5 Brake Map (0=None, 1=Left, 2=Right)
//6 Wheel Radius (feet)
//7 Steer Angle (degrees)
//8 Static Compression (feet) (0 if rigid)
//9 Max/Static Compression Ratio
//10 Damping Ratio (0=Undamped, 1=Critically Damped)
//11 Extension Time (seconds)
//12 Retraction Time (seconds)
//13 Sound Type

Need to ask one question. How fast is you taxi speed ? as this doe's have an impact on inertia.

Yes, usually when you tilt from side to side on the ground you are going too fast. Unless you have changed them, there shouldn't be anything wrong with contact points on default planes.

I would probably have to agree with the first two comments made.
A good rule of thumb max 25 mph taxiways, and slow down for the turns. Save your flying for the air :)

Information on the points can be found here http://msdn.microsoft.com/en-us/library/cc526949.aspx

In the first row the class of the point is defined. 1 are wheels. The first three points are wheels .0 is the nose wheel, .1 and .2 are the main landing gear wheels. They are each 6.76 ft to the left or right of the middle. You could try to increase this distance and do a testdrive. There's a reload aircraft function available in the controls. I don't know if its assigned by default. After editing the aircraft.cfg you can easily reload your aircraft to continue testing. Of course you could also try to alter the damping. Changing the wheels lateral position should not have any visible side effect than the one you want.

I am not sure of my taxi speed but I do not think it is over 10 mph but I could be wrong.
I will look in to it when I can and let you know.
Another curious question is are the contact points the same in FS9 aircraft of the same type
example CRJ FSX CRJ FS9 ?

I can't compare FS9 and FSX cause I only have FSX since a few years and before I never worked on points with FS9.

Thanks for the answers I will check it out if I have to i will put a auto taxi system into every aircraft I have I can easily steal it from another aircraft I have.
Since I have FSPANEL STUDIO adding a gauge is as easy as falling off a log.
