I got the GF-Mcp-Pro at the GoFlight booth during the FlightSim conference in Las Vegas. The representative at the both sweared that "it works with Prepar3D V.4 without a glitch" upon return home I installed the software and...to my surprise and disgust it didn't work. Customer support just informed that I NEED TO BUY ANOTHER EXPENSIVE PIECE OF SOFTWARE TO GET IT TO WORK IN PREPAR3D. Totally unethical and misleading sales statement.
