D.520 dive speed and G force tolerance

[cacha]

First I'd like to thank Daidalos Team for this awesome new patch.

I was trying the D. 520 and found that it is nearly impossible to break by pulling too many Gs. I tried diving from 10k meters and it only lost a wing at the very end of the dive, at 920km/h. Applying full elevator at over 800 km/h doens't kill it either. Is there something wrong with the flight model, or ir the plane really that strong?
