uncommanded rudder trim

[teeb57]

im running windows vista fs2004. i have all buttons & axis programed using fs. today my rudder trim decided to grow a mind of its own. when i start fs everything loads fine except the right rudder trim. i get a full right rudder command & i cant correct with any amount of left rudder trim. i tried flying like this and now know the trim is actualy in its indicated full right rudder position. this is occuring in all aircraft, pmdg & 2004 aircraft, regardless of wether fsuipc is applied to that specific aircraft or not. i had this problem before but was easily corrected once i disabled the joystick in fs. thanks in advance for any suggestions. also, I have a saitek yoke as well. maybe thats where i need to start looking. steve

Sounds like there's some assignment not working as you would wish for in FS.

If you have FSUIPC installed, you could use the Logging facilities to see what is happening. enable Button, Event and Axis logging. It will show all those types of commands getting to FS, easy to understand in the LOG file as the commands (controls) are named.

thank you pete. i have fsupic installed & checked off buttons, axis & event on the loggs page. after running fs, i went to the ini file but dont realy understand what im looking for in terms of button or axis commands. ive seen all the commands in the log files & tried to read what it is that im supposed to be looking for but im afraid i dont understand any of this yet.

I don't know why you are looking in the INI file. Who mentioned that?

ive seen all the commands in the log files & tried to read what it is that im supposed to be looking for but im afraid i dont understand any of this yet.

Try searching fro the English words "Rudder" or "Trim"! It is the rudder trim you said was going awry, wasn't it? So why not look to see if such events are actually occurring as a first step?

Paste the log here if you still do not understand, or English is not your language, and I'll have a look. But if it is not today, I'll not get to it now till May 9th as I'm away for the week.

Best list all the add-ons you are running in FS too -- I've never heard of a runaway rudder trim problerm as virtually nothing uses the rudder trim in FS at all.

yes, rudder trim is the problem. but where do i look to find what the trim is doing?

Search the LOG for the actual words Rudder and/or Trim, as I said.

I'm afraid I won't be able to help now till after May 9th as I'm off in a few hours and not back till then.

i hope you enjoy! thanks for that quick response

[teeb57]

ok, i give up. the unfortunate aspect of this is that i now have to confess that I’m a dumb **s. i still don’t know what or where I’m supposed to be looking.

exactly WHERE do i look to search for the words rudder or trim?

I’m not sure what is meant by quote "Best list all the add-ons you are running in FS too -- I've never heard of a runaway rudder trim problerm as virtually nothing uses the rudder trim in FS at all."

i don’t have a clue of all this computer mumbo jumbo let alone what’s using rudder trim. that’s sure not your mistake pete, its mine. all i know is that i cant fly or practice emergencies or engine outs with no rudder trim. i sure cant use a rudder with uncommanded full deflection. All I do with fs 2004 is practice hand flying or emergencies until I’m recalled back to the airlines. fsuipc has been a great tool so far. thanks for any help. steve

Start FS and then open the FSUIPC dialogue window. There is a tab called LOGGING. You can create a LOG file which you can then look through to see if there is a mention of rudder or trim. This might give a clue what your problem is. If in doubt have a look in the FSUIPC user guide under Logging.

How do you know it the rudder "trim" that is the culprit here, and not for example just a badly calibrated (or broken) joystick? Can you see the rudder trim indicator in the cockpit ?

[teeb57]

thanks pschlute. yes i can see the rudder trim on all aircraft. when i open fs, the rudder trim is in the nuetral position. the moment i move any axis or push any button, the rudder will then move to full right deflection, i can watch as the rudder indicator goes thru this. when all this started i did a complete calibration of the joystick & everything checked out fine, so i dont think the joystick is the problem, but i dont know for certain.

ive read & reread the users guide more times than i care to count trying to figure out how to apply the logging. your input is a big help. thanks for your time & suggestions.

[pschlute]

As you say that this does NOT happen if you select DISABLE JOYSTICK in FS then it is clearly an assignment issue. One of the jotstick axes or buttons is commanding rudder trim. Check in FS assignments for the keyboard commands for rudder trim. It may be that you have programmed the same commands for another function on your joystick software.

My advice would be you delete the rudder trim assignments in FS and see if that fixes the issue.

[teeb57]

i deleted this rudder trim assignment sometime back but still had the same problem. you gave me an idea i hadnt thought of before. i went back into assignments & deleted ALL assignments in fs. that took care of the problem. all is right with the world again! thanks for taking the time helping me out. that was getting to be a tad frustrating

[Skittles]

Sometimes FS will reassign default buttons and axis. If you find it doing so read THIS

[teeb57]

thats interesting. i suspect ill be learning a lot about all this for a long time to come. i have to say, what i thought was impressive was the control console and rado racks!! i was waiting to find a circuit breaker panel in there some where. very nice!!

Are you talking about my GoFlight setup?

[teeb57]

you betcha! i had never heard of goflight until i saw your post. great stuff

In the LOG file, the file we were talking about. If you take bits completely out of context you are bound to confuse yourself! Please read the whole message not part of it!

I’m not sure what is meant by quote "Best list all the add-ons you are running in FS too -- I've never heard of a runaway rudder trim problerm as virtually nothing uses the rudder trim in FS at all."

I don't understand. Which English words aren't you actually clear on? There's no mumbo-jumbo there. "List" means "make a list" -- i.e. itemise, like a shopping list (you ever been shopping?). "Add-ons" are thing (programs, aircraft, scenery, etc) you've ADDED ON to FS, ones you are running at the time you get the problem. After all, if your controls are okay and your settings are okay it must be something else you've added to the system which is doing it!

pete, i saw earlier where you said the "log" file. i 1st looked for the log file in the module folder then looked every where i possibly could in fs9.... no joy on any log file any where on this computer.

no need to respond to this message pete. it will take me some time to get caught up with the rest of the computerized world. my shopping list looks nor sounds anything like this. maybe i should get my 6 year old to explain it to me. no ones fault but mine. it has worked great now for the better part of a week, so no complaints from me. good day to you

If there is no FSUIPC.LOG file then you have never ever run FSUIPC, so all these questions are moot.

I suspect you are seeing the log file but have Explorer set to hide the filenames from you. Go into its folder options and uncheck the option to hide known file types from you!

it will take me some time to get caught up with the rest of the computerized world. my shopping list looks nor sounds anything like this.

Anything like what? There is NOTHING in my question which requires ANY knowledge of computers whatsoever. You have a computer. YOU added Flight Simulator -- so FS is ONE of the things you added to it! You added FSUIPC, so that's another. Maybe you added Scenery, or Aircraft? Surely a list of WHAT you added is not such a tall task? If you really don't remember what you've done at all I can only suggest you start again from scratch: even to the extent of reformatting your disks, reinstalling Windows and FS and so on, making a careful note (yes, a list) of everything you added to your computer! At some time, if not now, you will really need to know what you have as against what you don't have!
