I just bought the 727 myself last night...she is a real beauty.

IMO, the remaining bugs do not really detract from operating and enjoying this aircraft.  That said, I still tried to fix some of these little issues.

So far I have fixed the non functioning heading select switch in the vc.  All it took was some hex editing and now it works perfectly.  I'll post the fix in a separate thread eventually.  I also want to get CS's approval first.

I will see if I can fix any of the other bugs as well.  For the smoke issue, all you have to do is press "i" to get the black smoke.  I'll probably make an xml gauge that automatically triggers this.
