If you are using a dedicated throttle, you probably followed the kluge set up of binding “Throttle Forward” to your HOTAS throttle and then inverting it through the controls menu. the problem here is that, not only does it not work very well, but you now have lost the ability to bind something to ’strafe‘ forward. We need a dedicated bind in the flight movement sub menu for just Throttle Abs. And Throttle Rel. This existed from 0.x through 3.4.x, until now.
