Kicking the rudder is, imho, a great way to kill speed in dog fight. I have a Thrustmaster with a twist rudder, and I have it scaled so that the first 40% of the application of twist only builds up to 10% of actual rudder movement, then from 41%-100%, it travels the remaining 90%. So if I'm diving in on someone and I want to control speed, I'll drop throttle and initially make my move to a point past his line of travel, then use rudder to line me up the rest of the way in. So I can crank rudder with a big twist, then line myself up with finer range at the lower end. It also kills speed, which in a dive that you're trying to control, is very helpful.
