FSX – MiG-31 Firefox Updated. The fictional Sowjet Mig-31 Firefox is based on the movie “Firefox” from the 1980s starring Clint Eastwood. This is a panel update of this futuristic looking aircraft, featuring both a new static VC (non-functional gauges) and a new 2d panel. All the gauges are now FSX/ Acceleration compatible. Automatic burner and smoke added. Thanks to Owen Smoot for the original model and to Bob Chicilo for his previous FSX update.
