In this scenario, and experienced multiple times in-game, when you're missing 1/2 of your elevator in the B-24, the flight model seems to be incorrect. Please see the accompanying video.
This only occurs with the B-24 is missing 1/2 of its elevator.
Notes:
Don't pay too much attention to the commentary. It's made for reference purposes at the time and in no way tries to infer "absolute knowledge" of IL2, its flight model, etc.
It's merely... circumstantial. It was recorded to go along with the track (also attached).
Adding power to a B-24 in 4.13.3m with elevator damage brings the nose down, not up. Decreasing power brings the nose up, not down.
This is "counter intuitive" and is so much so that I had to make this post and video to have it looked at by DT.
