After i pull up from the dive, some of the time a skilled pilot will stop his dive and keep climbing back into another roll over the top, all the while i have already banked left or right,(he will now be entering that roll over) and i am now proceeding away, and down "getting speed" as he now notices i am 2.0+ out he will start to come back, by then i am already in a diving turn still keeping speed, buck the nose up... target, and fire.
Again, a skilled pilot will see this coming, he too will nose up and return to a climb, hopefully you can track him or get a gun solution, if you can, take the shot.
I fly the A20G, and it works very well for me.
That is all.
