Not sure why the only guys that responded to your thread are in the same squad of the guy you insulted in another thread, but hey, we can all have off days.
First off, turn on the Track IR object relative mode (it may be called something different) otherwise gunnery is a real pain to get accomplished. I also have a Track IR as well, make SURE you get the Vector enhancement, well worth the money.
I'd be willing to help you out as well, I don't know a whole lot, but maybe I can help either in the TA or the DA.
As I said before, I'm 90% aim and 10% acm, but I'm willing to help.
