Last night, I tried something new when I encountered this and think I may have found something. I wish I would have recorded it but in the heat of combat, I got caught up in the moment. I was flying a pony on the tail of a Corsair when it happened (no it wasn't Dogg). I had more E but it wasn't huge. While pulling lead and shooting at him (he's buried in my dash at the moment), I noticed him appearing, going vertical out of the front left quarter of my cockpit (we were turning right). As soon as I saw that, I leveled my wings, pulled up and barrel rolled opposite his. I exaggerated the vertical in my roll (but not too much cause I did not want to create too much separation) and soon saw him come out of his roll. He then tried to point his plane directly at me. Now I'm above him looking out my right rear quarter panel at him. I can see hes trying hard to pull up into me, there's about 1.5K of distance between us.
At this point, I could have aborted the downward side of my roll and pulled up for a possible rope; go level and extend, dive and extend. Instead, I chose to go on the offensive and try to hang on as much E as possible. I pulled back slightly on the throttle, dropped a notch of flaps, put myself in lag pursuit and kicked right rudder. My pony whipped around like a top and was diving toward him with him coming up at me. I got my nose around faster than he did, went into lead pursuit and pulled off a snap shot.. Boom!
So what did I get out of this? There is a fine line between playing it cool and preserving E and then flying aggressively and cautiously expending E. In this situation, staying aggressive allowed me to burn off alot of his E and keeping the pressure on him.
Let me know if this tactic works for you.
