Make sure you have your device set to max sensitivity if you are a tilt flyer. I aim just a hair above and left or right of center for sniping. If you aren't scoring hits, maneuver and retry. It is always better to be high in a dive than climbing up for combat. Reduce speed for half a second in a turn to make it tighter. Be sure to thumb the screen around to see what your enemy is doing. Flying in a spiral will get you killed in turn fighting. You might google some aerial combat moves like a "split s" and practice them. Never ignore a bad guy on your 6 or flank. See you in game, Sarge!
