Late Update on my experience with the T.16000M FCS that replaced the T.Flight HOTAS X series which died on me like flies :
- it as well dies with the exact same failure symptoms (Stick twist going erratic, ghost inputs, then non-recoverable decalibration issues) as the T. Flight HOTAS X
I can only assume Thrustmaster used the same cheap and unreliable faulty wiring for the stick twist in both HOTAS Systems.
So this far, no single Thrustmaster HOTAS has exceeded a lifetime of 4 months (and that's with alot of accepted degradation already) with me and the failures were basically all identical.
( surprisingly, it made no difference if they were used like raw eggs [Exploration] or heavy duty [intensive Combat] )
I'm seriously running out of ideas now and I definitely miss the durability of the old Joysticks of the 8 / 16-bit era

= I'm all open for suggestions at this point
