Hi everyone.   
First, my setup is as follows: 
Blackshark controlled with Axis inputs of:   
Freetrack 2.2 
Mouse 
Saitek X45 
Logitech Driving Force Pro (Using the gas/brake as rudder pedals) 
The trimmer works as it is supposed to when the pedals are disconnected, and I'm using the throttle's built in rudder. As soon as I plug my Logitech wheel in, the trimmer responds when you hold T, but as soon as I release it it does NOT lock the controls in (using the red control input view to verify).   
The pedals themselves do a fine job, and worked perfectly for me in lomac as well.   
Any ideas? I tried disabling force feedback in the options menu, but that did not help.
