Calibrating solely rudder centering

[dhlair1]

Help please. Just need to center my rudders with fsuipc. I select direct to fsuipc, chose "rudder", untick fsx use controls etc, and see all numbers changing and here's the problem. Twisting all the way right and left appear with different numbers when centered and need to calibrate to stay centered which never happens and always pulling to the left while aircraft moving or taking off. Appears I have to modify the numbers to achieve this but not sure how. Can someone give a hand just for this particular rudder issue? Rest of the axis are performing well with the fsx game settings. Thanks

First, you must NOT allow axes to be assigned in FSX and also in FSUIPC. If you are using FSUIPC for assignments, to buttons or axes, you need to disable each game controller in FSX.

If you then do decide to make use of FSUIPC's facilities, you will find a User Guide in the FSUIPC Documents subfolder in the FSX Modules folder. Look up Calibration. Follow the numbered steps and you can't go wrong.

Thanks Pete, I believe that is what I'm doing without results. While FSX is running I delete believe is the X axis for the rudder in ga.e controller and then untick "use game controller" in FSX and proceed to assign axis X (R) "send direct to FSUIPC" and chose and tick rudder, then to Joystick Calibration in FSUIPC in first page of 11 to calibrate the R for rudder. Then OK and still pulling left. What am I missing? Sorry, hope I explained clearly and appreciate your help. Steve

Its normal for prop aircraft to pull to the left during take-off - see this post an explanation:

You need to compensate with a bit of right rudder.

John, not a prop. It's the default 737. Steve

You evidently either aren't setting the centre zone properly when calibrating, so the output with a centred rudder is not zero as it should be, or you have rudder trim set off-centre.

The calibration screen shows not onlt the input but also the resulting output. Centre the rudder, the output should show zero. move therudder a little each side of centre. it should still show zero.

If that's okay, it'll be your rudder trim.
