Bat:
Look, no disrespect, but his needs to be put in perspective.
Every time you post a film, it is based on not only as Anax pointed out, usually a lack of gunnery and throttle control on the opponent's part, but an almost supernatural ability at gunnery on your part.
It ain't gonna happen for most people most of the time. Not the overshoot part, practically every furball involves using an overshoot to defend yourself at one point or the other, but turning that overshoot into a kill against a plane that has energy on you a large percentage of the time-ain't happening for most people most of the time. I say this as someone who has conservatively spent 5-6 hours a week practicing gunnery ALONE for the last two years. So kudos to you on your mastery of a incredibly difficult stunt, but advising the average AH pilot to fly a K-4 beneath the crowd and shoot whatever runs in and overshoots him is a bit like advising the average schmuck in a self-defense course to walk into a biker bar, start trouble, and take down his attackers with head-kicks.
