Well, with XML modding there's MaxHeadingAngleAdjustmentRate and MaxVelocityAngleAdjustmentRate, the first one changes it's turning speed, the second changes the speed of it's direction of travel, so basically if the Heading is greater than the Velocity, the missile would drift, if Velocity is greater than Heading, the missile would "drag itself", if you put high number on both of these the missile would be very maneuverable, for example, say giving it 570 would make the missile comparable to the R-73E missile, while giving it 10-20 would make it comparable to the R-40TD or the AiM-54, to make it maneuverable give both a high number.

Well there's a thing called maxHeadingAngleAdjustmentRate and I don't know if I should put it to a high number or not
