Cameron, Thanks for the replies. I am aware of all the setup functions as you suggested and I tried many of them; however, I gues I didn't explain the throttle issue very well, so let me try again. I experienced two issues with the throttle; the first was the reversal function and the second was a performance problem. On the reversal; yes, by clicking on the REVERSE selection box, it will reverse the operation. My observation here is that in the setup screen, with the REVERSE un-cheked, the green slider bar follows the actual axis movement; that is, full back = no green slider bar = idle = minimum analog value. And, full forward = max green slider bar = max throttle = max analog value. The second issue is indepentent of the reversal issue. What happens is, if I move the axis to its extreme, either max or idle position, the throttle displayed in the cockpit will snap to the opposite position when the extremes are reached; That is, if I move the axis away from one of the extremes, and if I keep the axis away from the extremes, the cockpit throtle follows the axis movement, but, if I move the axis to full forward the cockpit follows to the full forward and then snaps back to idle. (Visa-versa when moving the axis to idle). Maybe this is a problem with my equipment, but it all works perfect with MSFS, the CH calibration software; and the X-Plane Setup Screen. I treid it with the aircrafts provided with the X-Plane package (C-172 and B-747).
