So yay for the ngx, great plane, but when i got to altitude lastnight i noticed my contrail was black, flat and had square shaped graphics trailling behind. Turns out the smoke from failures, landing, and contrail are all like this, i've included some pictures for clarification. I am using rex which could be the culperet but i'm certain rex and the ngx are compatible, they'd have to be right? Has anyone experienced this? ---------------------------------------------------------------------------------------------------------------------------------------- Michael HeadWin 7, i7 @ 2.66 Ghz, 4Gb DDR3, ATI RADEON 4250
