The question that may arise is the latency and the speed of response is affichage.La it'll all seems well synchronized and I have not yet found slowdowns (but I don ' uses one of these modules to do with several). Otherwise there is a possibility to use 2 PC connected in network and assign the management of these modules to a PC and the other to manage FSX: everything is explained in the documentation.
Finally, in searching the net there are additional instruments to download. I found engine instruments and EADI allows multiple instruments into one. Finally for the brave there is a SDK to create its own instruments.
So overall a great product that makes you want to have at least 3 to drive without a dashboard screen and believe in a beautiful plane!
Update: Still satisfied with the product, moreover I fell for two additional instruments ...
