Same here Daube. After closing the Sim and then restarting, all seemed fine. Pretty odd!
I notice that the plane seems to have an end flight state save, like the A2A Cessnas. So if I end mid flight with full throttle, then when
I load the plane again, it loads on the ground with the engine at full throttle. So like the A2A's, when I end, I make sure the throttles
are pulled back for the next flight start up.
Also, the plane uses an .xml file install. But I noticed that the SimObjects folder is packed a bit differently from other such folders in
.xml documents I've seen. Usually there is an Airplanes folder inside the SimObjects folder, and then the plane folder(s) inside the
Airplane folder. Here, there is no Airplane folder, just the plane folder and other payload folders inside the SimObject folder.
I don't know if that makes any difference, but after reading here, I decided to be pre-emptive: I created an Airplane folder inside
the SimObjects folder, moved the plane and payload folders into it, edited the .xml add-on document accordingly, and everything
works fine.
I don't know if that's any help.
