Dumb AI

I have the Combat Jet Trainer mod for CFS2 featuring the L-39. I have modded one of the L-39's so that it shows up as an AI aircraft so I can go L-39 against L-39. The problem is that when the AI is flying an L-39, it's completely lame. It just flies straight and eventually flies into the ground. If I happen to be in it's path it will take a shot at me but it won't try to pursue at all. What do I need to do to make it try to chase and fight?
