I use an X52, and didn't play during 3.10 when they changed the flight model. In 3.9, after loading the x52 profile the throttle worked exactly as I expected. With 3.11, I can't control it, and it's hard to describe the behavior. Sometimes, as I increase throttle, it works for a second, and then immediately sets the thrust back down to 0 until I slightly move the throttle again. At other times, it's put me at full thrust no matter how I adjust the throttle and the only way to stop the ship is to reduce the speed limiter to 0. If I touch the throttle again, I'm back at full thrust with the speed limiter back where it was originally. I've tried deleting my user folder. I've reset the axis in the control profile to make sure the forward/back on throttle is set to the correct axis. I've used gamepad tester to verify that the throttle is working correctly. It ranges from -1 to 0 to 1. I would like my throttle to behave where fully back is 0 thrust like it did previously. I've made sure that this isn't an issue where it wants me to be at the center (0) position for zero thrust. It's just funky. Has anyone else run into a problem like this? Any ideas of what else I could try?
