FSX – Northrop P-61B Black Panel Update. This is an update to the Peter Mercy CFS2 Northrop P61B Black Widow panel. All of the included gauges are FSX compatible, just allow all of them to run when prompted. Installation has been simplified, just copy the Effects and Modules folders into your main FSX folder, and replace the panel and aircraft.cfg in your Northrop P-61B Black Widow folder with these new files. As was the case before you have a 2D panel and a non-functional VC panel. This panel requires the NORTHROP_P-61_BLACK_WIDOW.ZIP. By Michael E. Roberts.
