Hi. I’m having exactly the same problem. I am using a Thrustmaster Hotas Warthog and, when I move the throttle forward to open it up, the revs increase and then fall back. The more I open the throttle, the more the throttle seems to close. Raynen suggested checking to see if more than one axis is bound to the throttle in error. Is there a quick way to check for this ? also, has anyone else had the same issue and managed to solve it ? All help would be gratefully received. Many thanks, Ed
