I have installed all of my devices into the FSX and was able to troubleshoot everything to get it to work by reading different posts, except for the trim wheel.

I am able to use it normal during pitch up operation, but pitching down it jumps from the neutral position directly to up which causes the aircraft to dive down. I have checked all key assignments and I also set sensitivity to high and null zone to 0

 

Any Help There, Here is a video post

 

 

 

Well I am in P3D but probably will not matter

 

 

Make sure trim wheel is selected for both areas (calibration and axes)

 

Calibration - sensitivity - max and null zone is 0

 

Axes - elevator trim axis - keep spinning the wheel for it to take you should end up with x axis and dont click reverse option
