I've sold my X52 to upgrade but one feature I loved about it was the scrol wheel at the front of the throttle. When you leave mouse cursor hovering above HDG bug or other rotary selectors, it will disappear after while but you can still turn the bug with the scroll wheel on your X52.
btw, I'm preparing video to show you guys latest addition to my pit, including five rotary encoders. They are currently assigned to control AP and I have to say, It makes such great difference in VR that I decided to build whole radio stack too;)
This sounds great. Improvements coming from all directions. Thanks.
