The only problems I have encountered with the CS B-52, in P3Dv3.4.22 are:

1. That when I exit P3Dv3, it modifies my Prepar3d.cfg file - Specifically, it removes the default flight line, so that when I restart P3Dv3, it says that my default flight file is corrupt, and it resets to the flight with the F-22 Raptor ready for takeoff at KVPS, instead of the C-172 @ YMML (in a cold-n-dark setting), that I had set it to. The file is not corrupt, and it loads fine if I select it, but I suspect that this is not the file it saying is corrupt, but I can't figure out which one is, if any. Reselecting the C-172 @ YMML, and setting it as the default flight, P3Dv3 returns to normal, as if nothing was wrong in the first place, and continues that way until the next time I use the CS B-52.

2. I can't use the terrain radar, or P3Dv3 will CTD, which is a pitty, because I love the terrain radar in the B-52.

Yess, exactly endl3ss  . I've explained in detail how to fix the problem with the corrupted files.

It is important to move the "</SimBase.Document>" entry AFTER EACH Save of the flight/exiting PD3, to the end of your *.fxml File.

So for example, if you have save your B-52 Flight under "B-52 USAF" two files will be generated:

B-52 USAF.fxml
B-52 USAF.wx

So you have to edit the "B-52 USAF.fxml" how stated above and all runs fine.
