Sunday Beaver Update 14 Hello all, As you probably know I spent the last week on the S-TEC 50 autopilot and it was driving me nuts at the beginning, because my custom code was fighting with the stadard XP behaviour. However, I reached a state where the S-TEC can be operated almost as the real one. I guess most people won't notice it and won't miss anything. I am quite happy with it now. All availabel modes are working like STB, ALT, HDG, NAV, APR and REV. You can also manually roll the aircraft to a selected heading by using a rotary knob. I haven't done any AP constant fine tuning yet. This will be part of the flight model testing and tuning. I am getting closer to the development state where I could show a video for demonstration purposes. You all have a nice day!
