Yes i have been working on that aspect, but it's not yet been added to the published version. Currently working on a transform based "simulation" wich is used for distant units instead of physics based all the time wich is resource consuming. Both the AI as the physics. And regarding to combat air manouvers for now you can just set another aircraft as target for the autopilot and se max banking angle to 90 or more and it will do a more agresive flight. If you are using uSim Automated Weapon System (AI turrets) you can mount them as fixed weapons and have the turret fire between certain angle, and it will fire when the target aircraft is more or less in front. To make the AI more lethal you can add some rotatin range to the weapon (even thou it looks as fixed) and it will calculate some lead to actually hit something. But nothing like loops, evasive actions or anything of that sort.
