My pedals sometime careen. When I calibrated them the X axis is not zeroing out when the pedals are centered. See attachmentAny ideas?Barry

Hi,The x axis is for the left brake pedal and the y axis is for the right brake pedal. The y axis is for the rudder and should be centered on 128. Try recalibrating and see what happens.Ed

On my system, X and Y are the brake axes, and Z is the actual rudder axis.My X reads 16, Y=0, and Z=82 immediately after calibration, and with my feet off the pedals. The Z value doesn't really make sense; it should be around 128 which is mid-point for the axis (they all range from 0 to 255).Note that if I use CH Control Manager and put the pedals into mapped mode - i.e. as a "CM Device" rather than as a Direct device - the axis numbers are spot on (0, 0, 128). But both modes work OK in FS2004 for me (although I always use mapped mode, since I wanted to change the behavior of some things on my Pro Throttle).I don't know why your pedals are "careening", but you might consider using CHCtrlMgr to put the pedals into mapped mode, and see if you still get that effect. NOTE however that if do this, and you have other CH Products USB devices, they'll be converted into CM Devices as well and this may effect your controller (axis/button) assignments in FS2004. This is because the Mapped devices take on new USB ID numbers, and FS2004 thinks that they're different devices than the Direct ones.Good luck,Dave Blevins
