Hi,
I am mapping the trim functions to the trim hat switch.  Ailerons work fine.  Elevator - when I push the hat switch the trim moves to the middle and stays there.  It does not matter if I press the hat switch once or hold it, the trim indicator moves tot he middle and just sits there.  No amount of pressing will make it move again.  If I select combat trim, the trim indicator will move to that setting however if I touch the manual trim button again it just moves back to the middle.  I am unable to manually trim the nose up or down.
Hat switch works fine if it is assigned to views and the left / right trims work fine.
Not using TM software.
Ideas please?  I am forced to use combat trim and I would like to be able to manually trim.
