Back to you guys, I ran a couple of test as soon as I got back from work. here are my results so far : - I move the throttle of my HOTAS back to 0, no results - I unplugged my HOTAS, no results - I remapped control keys of the rover part, no results - I built a quick new rover with other parts, no results - I installed "stock bug fix" from our pal Claw (I though it was installed, my mistake), no results. BTW I narrowed down the problem a lot. everything seems to work perfectly when I want to go forward or steer any direction. Brakes seem to be working, even if quite weak. but once I hit the "drive backwar" key, it goes crazy:) Actually the rover goes full throttle instantly and keeps going as if nothing else mattered. I can still steer it but no matter what I do it keeps going "pedal to the metal". any ideas guys?
