Hello,
I noticed that the missile (almost) doesn't maneuver until the propulsion phase is done. Which does not happen if you shoot at close range (about 5NM and less). Making many missiles missing their target, especially at medium ranges.
Here is a short track that show the 2 situations: First 530 fired at ~8NM and miss the target, the second at 4NM doesn't miss (because it maneuver after the 2sec delay after launch). The target is an ace Mig29, without chaff. He's turning 90° on the left when the first 530 is shot.
