For nimble, also try the ju88 with 25% fuel too short of flights but 50% makes it just a bit heavy too... this is without bombs of course.
It has 2 of everything, just about, so by default, it has 'durability.'
Rear guns, most fighters line up riiight exactly behind it, where the ju88 can put some 'sting' - 3 mg's... no fighter can stay back there forever, so it gives the ju88 a chance if fighter is acting 'stupid' - maybe a better word, 'careless.'
Ju88's do turn, big wings, without bombs they are slightly light, someone want to post wing-loading and power-loading stuff? And the front mg again, has tons of amo, so can spray.
I once shot down an f4u after a few mins dogfight!

Difference between ju88 and he111 ???
The ju88 PILOT can fire his forward guns.
The he111 PILOT can not, he must first move to the station... BOO !!!
New wish, make all bombers able to fire their forward weapons with normal trigger!
Maybe have the 2ndary trigger connected to all the other guns to just fire straight out?
