Actually I tried it both ways. There were no directions that came with my wing. To me it looked the best like this.
As a pilot I can tell you there are NO forward swept wing's on any production aircraft. There have only been a few forward swept wing aircraft ever produced. The advantage is that a forward swept wing reduces the "Critical Mach" speed. And since I will mostly be driving at just under Mach 1 this doesn't seem to be an issue. Lol
PS: The front suspension & engine are now mounted in the back, backwards? So now it all matches.
