Maybe one for the hardware forum, but I thought I'd try the main one first as it's only happening in MSFS. Probably been there from the start but only noticed it when i glanced at the throttle on screen recently.
My TCA Airbus throttle behaves fine except for one instance - when the two throttle levers are sitting at idle, in the cockpit, the left lever is somewhere between 0% and perhaps 7% (that it itself I need to work out a fix for), whilst the right lever will always be around 7-12% higher. At any other setting on the physical throttle, the sim throttles will be matched, i.e. both at 10%, 20% etc. Even in reverse thrust, they match, so it's only at idle there is a problem. I've even used the screwdriver bar used for calibration to link them so that they move together - still the same issue. It doesn't happen in FSX:SE - the throttles move together correctly.
The difference doesn't seem to affect my flying noticeably but perhaps I'm just compensating, but ground handling is probably slightly more twitchy than it needs to be, I'd imagine. And with the new floaty/STO characteristics some planes have now developed, I sometimes find my plane veering off course after rotating. Perhaps unconnected, I won't know until I can solve this issue.
I've only used the Thrustmaster calibration instructions (moving to different detents and pressing the appropriate buttons). Anything else I should try?
