I have just recieved a pair of Siatek Pro Flight Instruments and I will have to report they are not an easy install. The first thing I had to do was update to .NET Framework 2.0 which for me was a very long download(dial-up). The next thing was when FSX started up the prompt for my Go-Flight equipment was gone rendering all of my Go-Flight systems useless. With all of that said the new instruments still did not work with FSX. I will be setting of on a mission to repair FSX and reload the Go-Flight software.
