I downloaded all of Bill Lyon's aircraft so I could put all of his scenery into one folder to share between my 4 installs and came across one of his planes that I did not have....the Quad City Challenger ultra light. How have I not been enjoying this fun little plane? It is a blast to fly. Sure, it's not fast. And sure, it isn't something you'd want to fly during bad weather....but man...flying it through the Canadian Rockies, down below the peaks of the mountains.....it is a great plane to do some scenery eyeballing in. I haven't flown it with my TrackIR system fired up yet....but I am going to.
