I have the X-55 as well and so far so good. The only struggle I'm having is that the Ka-50 Sim will not allow me to map axis commands to my stick. Throttle column map the collective and Throttle to the two levers as axis but the stick column is just grayed out in the axis commands and it's only in the Ka-50. Axis commands in A10, UH-1h etc are all functioning properly. Any thoughts?
