I flew around last night looking for B25's to kill, just so I could pay attention to how much damage they could take vs the F4U-1A.
The first one I came across was higher than me, but just slightly. I pulled a major no-no and approached from the dead six position, co-alt, with a slight speed "advantage". He shot back, but only hit me with a slight ping before he popped. He didn't even break up, he just popped. Bullets all appeared to hit his tailgunner, so I thought that was odd.
I continued to hunt B25's and found then extremely vulnerable. Tails get cut off, engines catch fire, wings break off. It was terrible. They appear especially weak if you hit them from above shooting the rear portion of the fuselage between the stabilizer and the wings.
How much damage did they soak up? Not much. I know that on one hop I landed 13 kills with no re-arms, and six of those were B25's. One of them did put a little hole near my wingtip. All told, I would say I wasted more ammo on that hop missing fighters than I did killing B25's.
The corsairs do hold a lot of ammo, but even so...
Maybe the B25 isn't the issue? Rubber bullets maybe? Something else?
