Hi, today I tried to import 2 aircraft (Carenado B58 and Alabeo Saratoga) in FSiPanel.
When I did it as described in the tutorial video I had the problem that my heading bug wasn't matching the compass and the course shown in the GTN 750.
What I did to solve it was...
I didn't do the HDG test, just ticked it to be controlled bei FSiPanel.
When I started a scenario I did NOT use move aircraft but slew aircraft instead, that did the job, at least for me.
Maybe this is helpful for other users!
