Elevator trim

[Shane]

The have the X52 HOTAS and set the X rotation to control the Elevator trim (within the FSX axis settings). I have ticked “disconnect Elevator Trim when AP is enabled” in the MISC tab, however it makes no difference and the rotation wheel still effects the trim, often in a crazy fashion!

Any advice please.

 

Thanks

Hi,

I guess you use a standard AC and not a add-on like A2A / PMDG / ... ? If not it might not work because mostly add-on AC use their own internal logic and gauges to control stuff like that.

As well as what Thomas says, is the axis calibrated in FSUIPC?  I'm not sure now without testing, but I don't think FSUIPC can disconnect it unless it can intercept it, and it will only do that if you calibrate it in FSUIPC.

If it seems "crazy" it is either because your X axis is not well calibrated, or possibly more likely because FSX is using the trim too.

Wow thanks for such a quick reply. I am using a 3rd party AC so that may be an issue. I have not Calibrated the X52 in USUIPC, so that could be it. I will try that. I have not removed the keyboard assginment in FSX "NUM 1 and 7" do you think that may be messing it up?

 

Thanks

Keyboard assignments do nothing unless you use them.

Test on a default aircraft first, always.

Thank you for all the help.

OK, calibrated the rotation X in USUIPC (Great product BTW, best thing I bought:)) Now it works when the autpilot is on the rotation x doesn't have any effect, trouble when the AP is off the rotation X is SO sensitive that it is unuseable!

Hi,

in that case you have three options.

1/ you change the trim effectiveness in its aircraft.cfg (located in the folder of the used aircraft), most effective, where you change the line elevator_trim_effectiveness = 1.0 to a lower value i.e. elevator_trim_effectiveness = 0.75 or less

2/ you can use slope in FSUIPC calibration that will reduce the amount send in low range but still the full range at each end

3/ you can manually increase the full range in FSUIPC4.ini file, normally the value would be i.e. 16383 and -16383 and you change those values to i.e. 22000 and -22000
