The pitch trim when performing a cold start still does not function.
Here is my latest post about the issue:
"I just went back into both 2.5.0 and 2.5.1 Beta and the pitch trim does not function on either one of them from a cold start.
Amazingly enough, when DCS 2.5.1 was first installed, the pitch trim worked as it should from a cold start. When the trim initially functioned, it was by no means slow like some have reported but moved along just fine. However, after changing video driver settings/game video settings, the trim no longer functions."
