DM - Spitfire wings made of concrete?

[spiderschwein]

After playing on the repka dog fight server several times I have some doubts regarding the DM.

Is it only me who feels the DM of the Spit is a bit off compared to the Hurri and the 109?
The Spit seems to be able to absorb much more damage than any other fighter plane in the game at least at the wings.
For example, I was never able to cut the wing of a Spit (and I shot a lot of them...), while the wings of a 109 or Hurri seem to fall off quite regularly when treated with the Minengeschoss.. though I could remove the tail of a spit a couple of times.
The effect of missing elevators or holes in the wings seems also a bit under modeled on all planes (compared to the old Il-2)...
