I have FSX running on a Win 8 (64bit) Dell XPS 8500.  I have CH Yoke, Throttle Quad and Pro Pedals installed.  I first allowed FSX to detect the CH products.  All the equipment worked as advertized, EXCEPT for the first Throttle Quad lever.  Inputs from that lever jumped around to the point that whatever Sim AC lever assigned also jumped back and forth.  For instance, I usually assign the first two levers as prop controls on a DC-3.  The left prop control would not stay still if the lever was in full retard position.  I tried calibrating the levers thru FSX but the first lever continued jumping around when in full retard position.  I then tried to calibrate everything thru FSUIPC (licensed version).  The first lever would not settle down.  I moved the TQ to another USB port but got the same results.  I'm beginning to think that the first lever has a hardware problem when in fully closed position.

 

The equipment worked correctly on my old XP machine running FS9. 

 

Every other lever on the TQ, the Yoke and Pedals work correctly in FSX.  Anyone have any ideas?

 

Thanks,

If you are assigning axes and calibrating in FSUIPC, ensure that you delete all those assignments in FSX. They must be deleted, not just inactive.

Thanks for the insight.  I deleted all the FSX axes assignments and will you know if the problem goes away.
