That's is one way of doing it. I don't have the patience for it though. If I come in with an advantage in a 1A I use the E to get in guns range in his rear hemisphere, then dump as much E as i need to stay there (which is easy for an F4U.) This results in either a quick kill or the con reversing and maybe killing me instead. Which at the least may be an interesting fight.
Probably not the best advice, but it is fun.
Yes, you are correct, when 1v1 and don't have to worry about other cons, I would do the same, but not to the point of losing the advantage. I would leave enough wiggle room and have a plan of egress if I don't get the kill. I have two rules for my style of flying if there are multiple enemies though;1) don't drop flaps ,anticipate enemies flight path and cross it. If you drop 2 notches, get the kill most likely you die shortly after) and 2)If I don't get the kill within 5 seconds of getting on an enemies six, I disengage as I have a habit of getting target fixation. Keep in mind, this is vs. multiple bandits.
Like you said though in a 1v1 the rules relax a little since I can keep my total situational awareness on my fight and not spend most of it looking backwards.
