Bumping as well to help him find as well.
This is what I mean about turns that cost little E. You don't have to go into a full G turn all the time. Depending on the speeds, positioning, and closure rate of the two planes, you can pull a low G shallow turn to get your flightpath perpendicular to their. Of course, some situations call for high G turns such as if you don't see them until the last moment, so situational awareness (like in every other aspect of aerial combat) is VERY important. The sooner you see them coming, the sooner you can maneuver against them. The sooner you can maneuver against them, the more E you can save.
As trainers call it "pointing your wingtip at the your enemy" is a VERY useful thing to do to create high closure rates, sharp angles, overshoots, or avoiding head on shots.
