Good morning Pete, I have added a BU0836X to my setup, using P3D V3, windows 10 and FSUIPC V4.955c. I setup my default Mooney Bravo with BCN, Landing LIghts, Taxi Lights, Nav, Strobe, etc., in the "on" position. When I close P3D and start it, the Mooney loads every time with those switches "off". I don't change the switch positions, load that same aircraft by going to Scenario and when it loads, the switches come up in the position I originally saved them as? This happens with any aircraft I use as a "default" aircraft. Is there something I'm doing wrong with the the BU0836X? I plug in a Desktop Aviator switch panel and I don't have this problem.
