X-Plane 11, Taxi problem.

Question

I have a really irritating problem, whenever I'm going to taxi with every plane, even if I dont touch my controls, the plane starts going to the left, a sharp left.. Anyone else has this problem? I've already reinstalled it twice, no solution... I hope some one can help me!

Hi, are your axis correctly assigned and calibrated? are you sure there is no assignation conflict in axis? Have you checked your rudder and trim deflection values via the "output settings"? Have you visually checked the position of the rudder and the front wheel? Have you set some wind? This is a very surprising problem.

---

I've checked everything even with no wind... The front wheel is standing straight forward, and when I give more power the plane goes forward for a few seconds, and then suddenly it goes left, front wheel  just stays straight..

---

Does it happen with jet aircraft or only with propeller aicraft? Can you counter this effet with the rudder, and is your correction more and more efficient when gathering speed? Can you be more precise about "every plane"?

---

It happends with every aircraft, prop or jet.. I can counter the effect with my rudder, but when I let go of it the aircraft immediatly turns to the left. Strangely enough, after landing it will be straight, but after my speed is low enough to go taxiing, it happends again....

---

And have you checked the rudder trim value ramains at around zero? Are you sure that your throttle axis is not assigned to the rudder trim by mistake, ot something like that? Tell me if you need more help to display the trim values.. I can soon check on my computer.

---

I have the rudder axis and throttle axis both on seperate things... Where can you display the trim values?

---

First picture : the result.

You will read the values on the top left corner.

Second picture : it shows what box you need to check in the Output data tab of the settings window. The search box will help you find the relevant line. You can enter "TRIM".

Make sure you tick the column called "show in cockpit" or something like that.

The rudder trim value should be close to zero.

You can also display other data related to rudder (search for rudder), like deflection, joystick or flight control and see how these values vary. It might help you find the source of your problem.

you don'ty seem to be the only one.. this looks like a similar problem.

I would also try to delete the preference files as described here :

(make sure you have the latest X-plane release also, just in case)

My trim ruddr value is always almost 0.0000, but my ruddr surf value (dont know what that is) starts at 0.0050 and when the plane accelerates it goes up... 

---

surf = surface, means how much is it move off center by the sim. (By trim for example or the turbulence) Edit: This may be my misconception.

your commanded inputs are from yoke1

---

"your commanded inputs are from yoke1" What do you mean?

 

And I've had the weather all clear, no wind, no 737 takeing off in front of me and causing turbulence... So the Sim itself is re adjusting the rudder... For nothing... ?

---

In my setup, joysticks inputs are from yoke1. But I can't reproduce your problem. My rudder inputs are 0.0000 when centered. Can you save a short replay and share it?

Answer 1

Ty an external view that allows to view at the rudder. I prefer to look from behind and above while taxiing. Watch for unusual rudder movements.

Comments

The rudder and frontwheel dont move at all... Only if I use my joystick to move them.

Could you say what hardware (joystick), operative system, add-ons active, plugins?

Thrustmaster T-Flight sitck x, no addons or plugins, operative system you mean windows or somethings? Windows 10...
