The throttles worked perfect until a week ago, when I slide the first throttle handel ( 4 engine config ) up, just a little, the throttle jumpes to about 70% in the game. The other levers work still perfect. Then I tried MSFS 2020, it workes perfect. Checked the calibration in Windows = perfect. So it is not the hardware. Has somebody any idea how to correct this ( Boeing 747-400 ) .
