My directional gyro uses 2 stepper motors (HDG_Vacuum and AP_HDG_Cmd) and 2 encoders (DG_HDG_Sync and AP_HDG_Set). They all work individualy, but I cannot work out how to get the dial and the heading bug to rotate together. When the direction changes the bug stays still.

In new version (9.53):

- Added new SimVim function used  as "HDG_AP_Bug" parameter for a stepper-driven heading bug. It calculates the correct bug position relative to the heading card, taking in account if the heading gyro used in the aircraft is vacuum or electric.
