Sometimes .50 caliber blows wing and stuff off with wing hits under 3 hits.. sometimes you can plug 15 .50 calibers in same spot and you dont see anything happening (of course with 109 that engine always starts leaking oil, even if hits were tail hits)
I think AH models weakness on the wing when it is being hit alot...
Sometimes just feels that wingtip rips off alot easier after few hits.
Once I flew P-47 with alot head on hits by 109 (ops, that 109 survived, forgot I had elevator gone after dive bombing + acks, fought for the fun of it), he managed to get my fuel tank leaking and then I flew to head on spitfire too.. I got him down and he holed me some more and got my rudder.
After all that and amazement that I was alive, and had flown for couple minutes, I pulled finally 3-4G and *whammo* both wings off.
