K, finally got to see it
Have to commend you on the nice shot/kill on the zeke. Being a 'good shot' is only a tiny part of why that was so successful, its the setup which leads up to it and forces the bandit out in front of your gunsight, and Bat has this down nicely. Course, it helps when the bandit is made from petrol soaked rice paper
Like Dano said, nice lag roll and throttle and flap control to force the overshoots. Overshoots are deadly, and for the really good players its their bread and butter, so n00bs watch you overshoots! Either do it with so much speed it dont matter as much, or be prepared to slow up in a hurry or end up fodder.
Bat, the lag roll that dano points out, you end up very slow, and as you pop a notch of flap, you VERY quickly roll to the left at 43 secs into the film. Looks like a small accelerated stall which produced the very quick roll
The hellcat dont roll like that at those speeds unless a wing is stalled. If so, nice just-in-time control to correct it (of course often those who can master the extremes of their flight envelopes have a decisive advantage too). Hard to tell as the film viewer doesnt show rudder or aileron deflections only flap movements.
