I am having the same problem suddenly. im only using an X52 no pedals, did all kinds of training missions, no problem. then suddenly when I was on the target practice map, the skhval starts slewing right. I can stop it temp by mashing buttons.. but it will keep doing it.
tried flying with no joystick plugged in. fully out of computer, still does it.
tried unplugging my keyboard. still does it.
jumped into freeflight, ground mode, skhval on..... still does it. so weird man. tomorrow ill try some training missions again and maybe set my deadzones to large, even though I had my stick unplugged.
