Also consider that the plane was deemed capable of divebombing with such high empty weight. Many of them were equipped with StuVi divebomb sights. However, I have not made such pull up yet that could have broken its wings off but it does not tolerate much damage when this happens.
I'd say that the max permissible loading figure for 410 may be right which makes it perfectly capable of divebombing, but the "hitpoints" against damage in wingsections do not correlate with the good loading figures and I assume that due to game mechanics these are two separate values.
Compare it with e.g. Ju88 which is also a dive bombing capable "stuka" aircraft. Ju88 is quite resilient to wing damage.
