This is not a complaint but it seems all the planes have a heavy exhaust trail. Like the all
running very rich mixture? Any way to get rid if that? I figure its probably left over jet exhaust code from Strike Fighters so probably cant make it disappear..

Yes. I can send out a VeryCleanExhaust that leaves only the slightest trace. It's what I use. I don't want to put it in every DATA.INI, though. Some people like it that way. I imagine you can find the line easy enough.
