I hace two MSFFB2. And It is happening the same bug with both.

Windows 10 pro 64bits.

 

When stick is perfectly center, and you unhand the stick, throttle automatic goes to 50%. It goes to correct slider position when you hold the stick again or uncentered stick.

 

Quick fix: I have to put a scotch tape in the hand sensor, so there are Forces all the time and never happen this engine behavior.

 

It doesnt happen before with 2.5 and windows 7.

 

 

Other thing.... No forces at prepar3d v3!!  what!!  :(
