Nose Wheel animation vs Rudder

Are you saying that when taxing, applying rudder to taxi, the rudder is moving (external view), but the nose wheel is not? What airplane, what flightsim program?
That's correct Mike and the airplane is a Cessna Citation XLS in FSX

Hi,
Look at the aircraft.cfg, contact point - steer angle (8th param). I suppose the animation for that is done in the model.
" //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

I've had that issue in FSX with the model. I did an FSX conversion with MCX for myself. It's coded properly for FS9 (c_wheel) in MCX with Tom Gibson's XML file, set it to c_wheel_fs9 and it will animate properly.
Thanks Brian,
No joy here. Gotta leave the PC for awhile, I'll have another go later.

The nose wheel animation would probably be an animation that is part of "c_gear" .....usually named it's "c_wheel".
If you open the model in MCX and look at the Animation Editor, I would try looking for "c_wheel".
If it is a custom animation, you can play the animations using the slider and check/uncheck each one on and off until you find out which one(s) apply. You can then go into the Heirarchy Editor to see all the pieces that are part of the assigned animation.

Success, sort of!
I was able to get the nose wheel to animate, however it turns too far left and right (90deg). so more work to be done to correct that if possible.
Ed, look at post #4 above and then check the value of column 8 (//7 because it starts at //0) in the contact points section of the aircraft.cfg file. It should be either 180 or a value like 35 to 45. 180 would mean the nose wheel was a free-castoring type while a value of 35-45 is the angle of steer either side of centre for a steerable nose-wheel.
Yea, I checked that Larry. It's set to 45.00. I think it has to do with the information in the hierarchy settings or the code I changed in MCX.

There are two "Model_Parts" sections to the nose wheel. The full assembly, and the assy that includes the piston, scissors, wheel and tire. It is that section that I applied the change to. The full assy is coded to "Rudder_Key" which kicks out the error seen above whenever I save the mdl file. There are only two options for that. . . ."Rudder_Key" which MCX says is incorrect or "Rudder_Percent_Key" which doesn't work. I changed that to c_gear, which works but allows the nose wheel to deflect 90 degrees left or right. So I'm sticking with this, at least the nose wheel will turn.

Make sure that the class number is correct in contact points, if it thinks its a skid it makes it solid....found that the other day....memory fade again!

20 is about right. I used to work for a charter operation that had two Excel's. Not much side to side on the real bird. Had to be careful when moving one with the tug
Thanks Brian, with this newfound skill I may go back and visit a few others that had the same/similar problem. . .see how much damage I can do to those, lol
