Rudder interfers with elevator inputs

CH Products rudder/ Logitech attack3 joystick. Installed FSUIPC 3.75. A few days later - lost elevator control on all a/c. After unplugging the rudder input cable the elevator began working normally. Any one know how to isolate the rudder/elevator/aileron signals so they don't interact with each other. Right now I send to FS as normal axis/ FSUIPC OPTIONS and Settings. Never had this problem before.

Hi Bertkuiper,

It's undoubtedly an assignment problem. FS used to recognize the pedals and make the correct assignments, but a couple of posts I've seen lately indicate that it's no longer doing that, but perhaps only for only the early versions of the pedals.

The toe brakes are probably the culprit. They're the X and Y inputs and, assuming FS is not recognizing them by name, will get the default generic aileron and elevator assignments. The rudder action will end up on the throttle.

FS will allow different controllers to control the same axes, taking input from whichever controller moved last. Usually what happens is that you set the ailerons with the yoke, FS responds, then the toe brake bounces by a count and FS responds to it. The toe brake is set to minimum when released, so you would get up aileron, left elevator, and about 50% throttle depending on which axis bounced.

Go into the FS Control Assignment dialog, find the pedals, and check the toe brake and throttle assignments, assign them correctly. The toe brakes will also need to have the "Reversed" box checked. Also, be sure to set the Slew assignments, you can be in for a wild ride if you don't.

Finally, it's a good idea to check the FS Sensitivity and Null Zone dialog. Sensitivity should be fully left, Null Zone fully right, for all three axes.

Give it a try and see if it helps. Good luck!

Best Regards,

Thanks for the interest and help. All settings are in place and correct. Application of right brake gives up elevator. All other control inputs correct and smooth. I even removed the right brake assignment to see what would happen. Guess what the elevator still goes up. Have a nice day.

Of course, because it's the elevator you need to de-assign from that axis, not the right brake!

There is nothing in any of FS or FSUIPC or anywhere else which "converts" brake input to elevator. you have another assignment somewhere.
