Hello. I got those two cfg files for the 757 freighter GSX configuration but i dont know where to place them. Help :) Im using p3dv4.

Got to C:\Users\AppData\Roaming\virtuali\Airplanes|create a folder of whatever 757-200/300 Freighter....................drop that GSX.cfg there.

Really surprised you do not know where to place them as they come with a full set of instructions.
