The B17 is without a doubt the most gamey plane in the set.
It's a deathstar (tm) and some people use it for extensively to ackstarr.
I distinctively recall a sortie where I easily blew down 2x262 and a TA152 that simultaneously attacked me at around 30k in MA. That's about as far from reality as it gets - I never even practised the gunning positions.
My hands were literally shaking at the sight of so many perk points, knowing they wouldn't down me unless they got a very lucky long shot with the 30mm. The lazer .50's smoked the others both engines, cut the tail of the other 262 and blew the 152 in pieces before they could land a ping on me.
