You need to look at how the release mechanism worked in the real plane.
If it couldn't release after a certain angle then is shouldn't release in here.
actually, one could take that a bit further and say if the aircraft didnt perform that role in the real deal then why allow it in AH? I'll be the first in line to say that Lancasters did NOT do laps around a single, or two, or three gv's in order to get a perfect angle on them for a dive bomb. I dont even have to look that up. Lancs may have done low level bombing raids at 1000ft and lower, but dive bombing gv's, or cv's, etc was not in the SOP. They were far too valuable to expose them in that manner AND there were far more effective aircraft for that role (direct support) than the Lanc.
Lancasters performed level bombing, while using the bomb sight, and the pilot didnt even have control of the aircraft.
