less fuel makes your plane more agile because its less heavy, nothing to do with ammo.

Now that is a revelation. I've been flying about a year and half and have read about everything I could, but this never seems to have been mentioned anywhere. I thought that less fuel simply allowed for a heavier bomb/ammo load and only affected the flying time. And since most missions I fly are of the short and furious off-line dogfights that end with me getting shot down anyway, having a more agile plane can be a plus point.

This is a very useful tidbit of basic info for which I am very grateful.
