If Fatty's not around, try this:
***Get really close. Like 50 yds.
***On some shots I use the zoom, but never even close to all the way zoomed in. With difficult 90 degree deflection shots on bombers, zoom usually doesn't help because it restricts the field of view too much.
***Don't use tracers on a fighter, except when practicing off-line.
***Sometimes the time to fire is when you can't see the enemy plane because it's hidden by the your plane's nose. This is especially true when you're very close and both turning hard.
***Make sure your rudder is centered when you fire. However, there are some shots, particulartly head-ons, in which stomping hard on the rudder as they go by will get you a kill.
***My convergences are set around 250 for most wing-mounted guns.
***When I think of anything else, I'll post it.
