Your statement yet again proves what a great place the internet is for disinformation. SPAD has never not worked with MSFS. I fly with it every single day. It also happens to be well supported and continually updated.
So, since you could not figure out how to use SPAD you call it “rubbish”. Once one learns how to use this tool and how powerful it is, there is no going back plain and simple. I am sure those that use AAO, Mobiflight, and FSUIPC feel the same way. However, all of these tools require a time investment from the user to learn how to utilize them.
