Hi Dieter: Yes, FSXpilot does work in P3dV4.1. It is not as handy as the Fassbender AP, but, it does work. It will fly the helicopter at a given heading, speed, vor, or gps track. It has a hover mode. It does take some getting accustomed to as far as how to use it.
Anyway, it does work. By the way, the gentleman who wrote the program is very helpful.
Regards,
Danny
