To expand just a little on the use of rudders in shooting....I've found two different but overlapping ways they become very valuable.
1. When reaching for an "out of plane" shot that you can't quite reach, you can use rudders to "yaw" the nose (and the guns) in a direction different from the direction of flight. Think of a drive by shot, with your car being the direction of flight (going straight) and the nose being the gun arm yawing to the side --
2. Once you have a good idea of exactly where to aim, you can concentrate your rounds right on that spot even when you're slicing past the target. (A non- tracking shot, or snapshot) Without rudder input, these shots are often like a strafing run, with bullets stitching a line along the target. Once your mind's eye sees the exact place you need to hit for perfect lead, instead of hosing the whole length of the aircraft you can throw in just a tweak of rudder to concentrate more bullets on the spot. Get this down, and targets blow up lots more (and you get lots fewer assists)!
