Thanks meh1951 for the explanation. I did install the Thrustmaster software that came with it and allocate the Throttle to JOYSTICK L-AXIS Z. For trim I also allocated the same buttons as you are and the Sensitivity is controlled by JOYSTICK SLIDER X. I also use JOYSTICK L-AXIS X and JOYSTICK L-AXIS Y for ailerons and elevator respectively. As it works shall I leave them then like this?
