It seems while most planes, payware or freeware, will work on fsrecorder's "play as traffic". But there are few exceptions. The QW 757 or any Project Airbus plane, if you "play as traffic", then fs does crash to desktop. It searched online and many people are having this problem without any solution yet. Its not due to the complicated plane, since even the PMDG 747 or the Project Tupolev Tu-154 works very well at "play as traffic". And its some parameters when recording. I've tried disabling ALL parameters on the PA airbus and it still crashes to desktop.
I'd love to see that QW 757 or PA 319 played as traffic, i need help.
