The just released Sky Dolly v0.14 focuses on improved 3rd-party aircraft support.
While not every aircraft system works as expected - specifically spoiler handle position and certain aircraft lights, due to aircraft-specific simulation logic that seems to „ignore“ (not implement) certain „events“ - most other systems should have improved, including flaps.
I have tested with a rather small „test hangar“:
- Fenix A320
- PMDG 737-800
- Asobo A320neo (the „reference aircraft“)
- And a bit with INI A310
But all improvements are applicable to all aircraft (no aircraft type-specific code in Sky Dolly) and hence other (3rd-party) aircraft should now work better, too.
