It's way too heavy empty. The 30mm weighs a little too few, and the 20mm a lot too many pounds. A 4x20mm loadout 190A8 should be the same weight as a 190D, but it's a lot heavier.
It's sort of like the info they had was for a sturmbock which was much more heavily armored, but as anybody can testify that's flown the A8 in-game against bombers it loses oil and wing guns on your first ping, so the armor isn't actually modeled.
So, yep. We got the wrong weights and our A8 is hurting for it. It would be nice to either get the up-armored version or to get the normal version, but we have the worst combo of the two. All the weight, none of the benefits.
