Two bits of advice I'll throw out there:
First and foremost, try not to rely on an aircraft's flat, sustained turning ability. It will very rarely be the deciding factor against an even mediocre virtual stick. If you find yourself banked 90 degrees from the ground with the stick yanked back all the way, looking out of the top of your canopy, you've done something wrong.
Secondly, use your engine. The throttle has far more positions than "WEP on" and "WEP off." In a low and slow fight, your engine can allow you claw above an opponent with a lesser power to weight ratio. In a disadvantaged situation, slowing down can reverse your position from defensive to offensive in seconds.
Beyond that, you really need some hands-on time. Learning ACM is a long process; typically in years, and it cant be fully explained in text. Sure, you can describe maneuvers and write out 'how-to' guides but, at the end of the day, you really need seat time to be able to get the feel for successfully mixing the then best option for the ever changing situation.
It is as much an art as it is a science and of the hundreds of options available for an infinite number of tactical situations, you need to be able to think 5 seconds ahead and employ the maneuver best suited to A.) What has happened, B.) What is happening and C.) What will happen.
If you can choose the best options for all three points of the fight, you get a kill.
