Just downloaded the EC-145 Rega V3. It is a great aircraft but I am having trouble with the autopilot. I set up for an ILS approach and believe that I have everything tuned correctly (the HSI bar is functional, the GS and LOC are on in green) but the helicopter does not automatically fly the course. It acts as though the autopilot is totally off. Any help would be greatly appreciated. Thanks for your time.
