Hi.
The 109 default convergence good enough. People overrated the importance of the low-distance convergence. The truth is, the current gun accuracy is so bad, the convergence doesn't really matters. When you shot from close distance, you probably kill the enemy with ANY convergence settings. But you can't shot it down from far, if the convergence is short. It's a fact, often noticed when we fight 1v1.
Improve the gunnery skill? I tell my favorite method: play offline, switch off the head shake, slow down the game, turn off the cockpit, and try to hit the targets with the shortest burst. The good thing with this method, you actually have to targeting, not just sprinkle a long burst, and wait for the enemy, to flying through it (and the slow motion is coool
, you see the flying bullets, the impacts, etc.). If you can shot it down every angle and distance, switch back the features one after the other. You will see, the shaking apply mostly the head, and not the plane (common error, if the pilot try compensate the head shake. Not only hopeless, but the plane much less shaking, than the head). Switch back the cockpit, the dashboard hide the view, but you will remember the lead, which have to pull to hit the target. Set the time back to normal, and you can follow the enemy with much accurate maneuvers (in the slow game, you should flying rather with calculated maneuvers, not with instinct. I like very mouch the slow practicing, very effective, and fun
There are many theoretical materials on the internet, one of the best is the Horrido Schiessfibel. You can download TX-Gunslinger's english translate form
www.mission4today.com/ You can learn the ammo types, the distance measuring with Revi, shooting angles, etc.
(We talked about a possibly new folders in the forum, it would be great, if the admins would make a separated folder for the combat tactics, flying regulations, theoretical materials. This topic is a best example...)
